Synchronous motors for your 24/7 operations

As leading providers of automated drive and control solutions, we only use the best products, sourced from the world’s leading manufacturers.

This means finding the products and suppliers which offer the highest quality, most energy efficient, reliable and cost-effective solutions for our customers.

For these reasons, we have been UK and Ireland suppliers and distributors of WEG low energy consumption motors for the past nine years, which enables us to provide our customers with the best WEG products.

This includes accessing the latest products and technologies developed by the German-based company.

This year, the WEG Group developed a new range of synchronous motors as part of a complete drive solution for demanding industrial uses and round-the-clock operations.

The new four-terminal permanent magnet range of motors have an output of 0.12 to 3kW, with speed feedback as standard, offer superior energy efficiency and can be tailored specially to the needs of individual customers.

High levels of energy efficiency are becoming increasingly crucial to any applications where there is a large demand on electric motors due to high speeds, large loads and the need for operations to be continuous.

The new WEG synchronous motor range can be used as both open loop and closed loop and exceeds efficiency class IE4 in all operating modes. Not only that, but energy efficiency levels of above 90% are recorded across a range of speeds.

Why choose synchronous motors

Synchronous motors are used increasingly in a variety of applications due to their special operating characteristics and the superior value they offer in terms of quality, proven reliability, low maintenance and long life in critical services.

They offer a number of benefits which makes them the preferred drive for a range of applications, including high efficiency, power factor correction, high torques and low starting currents, constant speed under varying loads and low operating and maintenance costs.

The new range exceeds required standards for small drives and benefits from superior speed accuracy and high dynamics due to a high overload capacity and low individual mass moment of inertia.

These special characteristics mean synchronous motors are often the best solution where operations have to be 24/7, such as pumps, compressors, chippers, shredders, fans and condensers. They are also highly adaptable to different and often harsh environments, such as mining, iron and steel, chemicals, energy transmission, cement, sanitation and paper.

Individual solutions for synchronous motors

Another advantage of the WEG synchronous motor range is that it uses a modular system which means it can easily be customised to individual customer requirements, including different add-ons and types of housing.

The synchronous range can be combined directly with the WG20 gear units manufactured by the WEG group, without the need for motor adapters, and using the CFW11 variable speed drives as the control units.

What to look for in a Distributor for WEG Antriebe Motors (Germany)

Certain high-tech industries call for precision and high-quality materials and products to ensure their production line is running effectively and efficiently. WEG Antriebe is a key player in producing 40 W to 1100 W motors for many high-tech industries, such as:

  • Plant/machine construction
  • Medical technology
  • Logistics
  • Industrial automation

WEG is a trusted name, a company that had humble beginnings. Originally founded for their production of starter motors for sewing machines, WEG slowly evolved into group drives and transmission belts until they specialised in drives with a 40 W to 1100 W power range.

However, due to the high-tech industries that rely on these motors, they need to ensure that they’re purchasing any replacement or first-time motors from a trusted distributor. How can you find a trusted distributor, though?

Look For a Company that Specialises in Your Field

Technical equipment should be greatly thought over before making a purchase. This is because, unlike buying a computer, technical equipment such as WEG Antriebe motors is the core of many drive solutions. For instance, by installing the incorrect drive in your car assembly line or robotics, this can cause havoc to your operating equipment and reduce productivity and efficiencies in the workplace.

If you do not have the knowledge yourself, then speaking to a company beforehand could save you a costly expense if anything were to go wrong. Plus, by working with companies like Alldrives & Controls, you’ll be networking with other companies until a solution is found; Alldrives & Controls welcome all challenges and have no qualms when reviewing your needs and requirements.

Working with professionals who have specialised in this field can help you find the right solution that is also cost-effective and right for your budget. Doing so can diminish any stress you may be feeling with regards to meeting a certain quota and not going over-budget.

Variety of Products & Authenticity

Look for a distributor who has a range of products so that you can see all that they have to offer. Although WEG produces motors between 40 W to 1100 W, there is only one UK distributor that deals with WEG Antriebe Germany and that is Alldrives & Controls.

What’s more, by purchasing products from a trusted distributor, the product you receive will be nothing less than authentic.

Ease of Contact

Alldrives & Controls allow you to network with companies within the drive and motion industry, so no matter what issue you’re having and what solution is needed, ( be it WEG Antriebe motors or linear actuators, etc) there is an unlimited pool of knowledge for you and your company to take advantage of. No challenge is too big or small, so if you need help with WEG Antriebe, Engel, Dayton or Nanotec, you can contact us over the phone or send us an email.

 Here at All Drives and Controls we work hard to select only the best manufacturers to completely meet the needs of our customers.  That’s why we are happy to recommend KB Electronics products due to their high quality, customisable AC and DC motor drives that are produced according to customer specifications.

Designing and building motor drives since 1937, American based KB Electronics know a thing or two about developing specialised inverters; this experience has now led them to develop a new Hybrid AC Drive range and DC / DC motor speed control that incorporate new features to cater for a wider range of application requirements.

The New KBAC Series AC Inverter Range

Boasting the same practical features as other KBAC series, the new KBAC 217 models are designed to operate from a 230 Vac line and up to 5HP; and the new KBAC-416 range will operate from a 260 Vac line up to 5HP from an AC line input.

Additional features of the new digital hybrid AC drives with analogue interface include a selectable jumper to switch frequency from 8kHz to 12kHz and GFCI (RCD); this provides the user with helpful options to suit a range of applications that require operation at constant torque or variable torque.

The KBAC S-models (suffix) contain an installed On / Off AC line switch that is equipped with a mechanical interlock to prevent the drive cover from being opened. The switch also boasts a safety lockout feature that can be used along with a padlock for complete safety against the drive being switched on while equipment is serviced.

To finalise this impressive hybrid AC drive is KB Electronics rugged die-cast hinged cover, the NEMA 4x / IP65. The watertight design is ideal for applications within sensitive environments as it can withstand harsh cleaning, wash downs and outdoor use.

The NEMA 4X enclosure provides further safety and prevention from electrical shock by preventing accidental contact with components inside and liquid tight electrical fittings for complete peace of mind.

Other options for the KBAC range include:

  • Forward-Stop-Reverse Switch
  • Signal Isolator with Auto/Manual Switch
  • Run-Stop-Jog Switch
  • Class “A” RFI/EMI CE Approved Line Filter

The Recently Released KBBW Open Frame

Always looking for new ways of working, KB Electronics has developed a battery powered DC / DC low voltage motor speed control model – otherwise known as the KBBW Series.

This low voltage speed control motor provides excellent dynamic response to load variations, making it ideal for applications such as solar pumps, portable pumps, carts, hoists, electric boats, chemical feeders and light duty conveyors.

The incorporated pulse-width-modulated (PWM) DC / DC motor speed controls produce an almost pure DC current, contributing to a longer brush life and considerably low noise production, with the pulse-by-pulse current providing short circuit protection and control damage prevention. Along with the Plug-In Horsepower Resister® (sold separately) the need for recalibration of the IR compensation and current limit settings is eliminated.

Additional well thought-out features of the KBBW 12 and 24 Volt DC Motors include:

  • Quick-connect terminals for connections
  • Adjustable trimpots for application tailoring
  • Undervoltage protection that shuts down the drive when the voltage falls below specifications to prevent damage to the motor.
  • An inhibit circuit that can be used to stop and start the drive electronically
  • A5-kΩ potentiometer, 0-to 5-Vdc analogue signal or a PWM microprocessor output signal to control motor speed.

Obtaining Your NEW KB Electronics AC / DC Motor Drives

KB Electronics dedication to manufacturing drives that meet a variety of customer needs is clearly evident within the new releases of the KBAC and KBBW series.

To benefit from the reduced energy consumption that these variable speed drives provide and to witness the enhanced safety and extended device life of the KB Electronics product line, contact All Drives and Controls for expert advice and your required order specification.

Ideally Suited Stepper Motors for UHV Applications

The ability to conduct precision research with experimental systems has advanced considerably since the introduction of vacuum technology.

Now with the use of ultra high vacuum (UHV) technology, extremely low pressure environments can be created to remove interference from gas scattering and enable surfaces to be atomically cleaned; allowing for preparation of studies in a completely contamination-free state.

However with such a demanding and sensitive environment it is vital that any mechanical equipment used be suitable enough to withstand extreme conditions, from plummeting pressures to temperatures ranging from -190°C to 200°C.

It’s true that not many mechanical components can claim to operate effectively under such extreme conditions, however the Ultra High Vacuum Stepper Motor is ideally suited for precision motor control inside UHV environments.

A Deeper Look into UHV Stepper Motor Design

UHV stepper motors such as manufactured by Arun Microelectronics Ltd, Nanotec® and supplied by All Drives and Controls are specifically designed for use in UHV environments such as cryogenics, space and nuclear industry.

The design of the UHV stepper motor allows it to endure hours of ‘baking’ in temperatures up to 200°C for the removal of water and trace gases for complete decontamination.

Then with the UHV stepper motor’s optimised construction and vacuum-compatible materials, it is able to operate in temperatures ranging from -196°C to +175°C, performing sensitive handling manipulations with precision without the use of motion feed through.

The minimal components of the UHV stepper motor and the absence of metal to metal sliding surfaces means that formation of any particles is minimised, this benefit, including its low out-gassing design characteristics make it a valuable device for ultra high vacuum environments.

Aside from its robust construction, the UHV stepper motor provides peace of mind with additional capabilities including:

  • An embedded thermocouple for temperature monitoring and control
  • Open construction with all internal spaces vented
  • Radiation-hardened versions
  • Custom shaft modified versions
  • A dedicated drive
  • Simplified connections
  • Torque ratings from 75 to 200 mNm
  • Suitable for use below 1×10-10mbar

With the ability to provide precision in-vacuum manipulation under intense UHV conditions, it’s no surprise that the UHV stepper motor was chosen for use on the Mars Rover.  

Designed to withstand intense heat and vibrations from launch to the ultra-cold, high-vacuum exposure on its interplanetary cruise to Mars, the use of a UHV stepper motor on the Mars Rover made an ideal solution for the robotic application that operates with such precision it can drop an aspirin tablet into a thimble.*

So it’s easy to see what makes the UHV stepper motor an ideal choice for ultra high vacuum environments.

With a range of sizing options and torque ratings available, All Drives and Controls is on hand to provide specialist advice on the most effective UHV stepper motor for your application; leaving you to focus on the more pressing matter of making scientific and technological advances.

Drive Efficiency with the Correct AC or DC Motor

Often hidden away, but still a major player in your motion control application, AC and DC drives are absolutely necessary for smooth speed-controlled operations.

However, selecting an appropriate variable speed control AC or DC motor involves more than just the need for simple process control; it involves consideration as to the most effective motor for your application and load demands as even the smallest change can significantly impact on efficiency and energy consumption.

If your application operates with various speeds for different processes, requires acceleration control or has altering rates of production or flow such as with conveyors, processing, HVAC, mixers, millers, elevators and hoists then your choice of variable speed AC / DC motor drives can make all the difference.

Selecting the appropriate drive (although only a small device in the overall mechanical function) can bring significant benefits including:

  • Increased efficiency due to smoother, trouble-free operations
  • Reduced energy consumption and costs from only using the right amount of power to match load demands
  • High precision for stopping and starting processes with smooth acceleration control to prevent mechanical shock, wear and tear.
  • Time saving motors that are simple to install and operate with no programming
  • Protection of your product from adjustable torque limits
  • The elimination of expensive components such as gearboxes

KB Electronic Motor Drives; the Right Choice for You?

The benefits variable speed control motors bring can easily be obtained when purchasing high quality, custom-designed AC / DC motor drives such as manufactured by industry leader KB Electronics and supplied by UK automation component specialist distributors, All Drives and Controls2.

However deciding which variable speed drive is right for your application from the range of hybrid AC drives and variable speed DC motor controls offered can be confusing.

For example, you may be aware that AC drives require less maintenance than DC drives, tend to cost less, are smaller and work better in high speed operations; on the other hand DC drives can be quieter, provide accelerating torques in excess of 400% and perform better with frequent acceleration and deceleration routines.

KB Electronics also produce a range of drive options including:

AC Drives: 3ph AC Induction motors from 1/8 through 5 horsepower or available in 15, 208/230, and 400/460 VAC – 50/60 Hz with 1ph and 3ph input.

DC Drives: from sub-fractional to 5 horsepower. They are also available in 115 and 208/230 VAC-50/60 Hz with 1Ø input.

Stepper Motor Sensorless Control; What You Need to Know

So you’re in need of a motor for precise positioning. What would be your preference?

Stepper motor or servomotor?

Many smart engineers like yourself will agree, that the answer lies resolutely in the application requirements.

For example, the compact stepper motor with its ability to run open-loop may be all that’s required for simple tasks, and certainly it makes a very affordable option.

However with high performance dynamic operations, the issues a stepper motor holds around resonance, excessive heat and step-loss often see it take a back seat to the pricier servomotors that utilise advanced control methods.

But things are starting to change.

The introduction of stepper motor sensorless control is already raising eyebrows in the OEM industry.

As it turns out, Nanotec® have found a way to replace expensive stepper motor encoders for virtual encoders within the controller. This means that our faithful friend the stepper motor, can now be operated just like a servomotor but without the high price tag.

Suddenly the query of stepper vs. servo gets interesting; but what does sensorless technology mean for us?

Less heat, no resonance, longer service

With stepper motors receiving a constant stream of full current, it’s no surprise that the resulting increase in high temperatures and vibrations decrease service life and eventually, effectiveness.

However now that the stepper motor can be controlled via the virtual encoder, they are able to receive the required current to perform actions, just like a servomotor. This ensures the stepper motor remains considerably cooler with almost no resonances.

This improved performance protects the motor and its bearings, increasing service life and naturally supplying the added benefit of energy efficiency. Better for the environment and for your bank balance.


Step-loss? What step-loss?

Another argument to avoid stepper motors is the issue of step-loss; missed actions caused by resonances and instability which of course go undetected with open-loop systems.

Nanotec® rectifies this with the closed-loop system that delivers a controlled current to the motor, so that resonances are removed and missed steps (up to its maximum torque) are a thing of the past.

The benefits of the closed-loop system now mean that the controller can recognise inconsistencies in the motor, adjustments can be made and alerts sounded.

And the mechanical issues?

Usually these can be minimised using precise mathematical models and calculating parameters, which let’s be honest, isn’t a quick and simple solution.

Thankfully the Nanotec® sensorless system operates with few parameters and even these can be set using an auto-setup routine that automatically determines all the required parameters. Now we’re talking.

All this additional motor control not only avoids instabilities and step-loss, but Nanotec® noticed that at high speeds, the sensorless control actually worked better than an encoder, even removing speed fluctuations of the motor at low resolutions.

As you can see, the argument for use of sensorless technology grows ever more compelling; yet it seems that’s not all.

Sensorless technology can benefit almost all stepper motor applications with its ability to be combined with open-loop control.  When necessary and at low speeds, the system is able to switch to open-loop mode; which still continues to work effectively considering resonance isn’t an issue where only a few steps are needed.

So it seems whether your application deals with speed, or positioning, this combined approach could work for you.

In the end, regardless of your motor preference, there is no denying that the main objective is for your system to run as smoothly and efficiently as possible. We believe Nanotec® have worked hard to provide this for their customers, with a responsive stepper motor that not only uses impressive sensorless technology, but doesn’t break the bank either.

Perhaps this calls for a change of opinion for future precise positioning motors? What are your thoughts?
