A high performance, sparkling clean servomotors suitable for hygiene or washdown applications

The Kollmorgen families of high torque density servomotors provide the widest range of features and options in the industry. These robust ranges allow users to select exactly the right motor for an application but without having to over specify and over pay.

The food industry regulations place numerous, often very stringent but necessary demands on system manufacturers and machine builders. However, depending on the application, the specific requirements for the motion components can range from simple to complex. It costs too much money to install an over specified motor especially in a washdown application. However it takes too much time and effort to modify a housing for a hygienic application. The Kollmorgen solution to overcome this expensive approach or indeed any other motor that doesn’t perform in the way that is required to, is to correct the initial product.

AKD WashdownConfronted with this powerful and diverse selection customers do not have to settle for just any motor. Engineers can select the exact motor for their application and get the job done properly, achieving optimal results. Whether the motor application is near a wet area or is required to be exposed to high-pressure washdown, the Kollmorgen families of servomotors provide a correct fit for a specific application.

HKM is the new range of stainless steel servomotors. They are built for drive tasks in packaging, food processing and pharmaceuticals. These sparkling clean motors, available in five sizes, are particularly suited for use in areas of the machine with direct product contact and where aseptic processes are carried out.

For example; drives with optional holding brakes for use in a delta picker robot. The launch of the size-2 HKM motor will mark as one of the world’s smallest stainless steel servomotors. With IP69K rated maximum environmental protection, the new range offers a torque density of less than 20 percent when compared with standard servomotors – avoiding the design limitations of other manufacturer’s stainless steel motors.

In fact, this minimal torque reduction (de-rating) is so good that a patent has been applied to protect the unique design solution.

A further highlight of the HMK series is its availability with the single-cable option for the Kollmorgen SFD digital resolver or hiperface feedback systems. At just 11mm diameter, the advantage is not only reduced cabling effort but also the need for only half of the normal cabling passing through your machine – plus it has only half as much stress on hygiene.

Importantly it is also good to know that EHEDG and FDA certify the new range.

AKD WashdownIn Summary the major features of the HMK motor are:

  • Single cable for both power and feedback, easier to clean
  • No other external hardware so smooth with easier to clean 316L stainless steel and highly corrosion resistant
  • Vented motor options (passive), reduces condensation so adds to the life
  • Full range of 19 motor sizes available – a best fit for machines
  • IP69K 1450 psi washdown sealing standard
  • Laser annealed name plate which does not harbour pathogens
  • No flat surfaces for puddling
  • Designed to EHEDG and 3A standards

Customers can also select from the robust line-up of the exclusive AKM™ washdown food grade models all with a proven track record for dependable, superior functionality and high-performance.

AKM Washdown series synchronous motors are a practical and cost-effective alternative to motors that employ high-grade stainless steel housings. With IP67 rated PTFE sealing, a special two-component epoxy coating and stainless steel output shafts these synchronous motors ensure complete resistance to corrosive chemicals including highly alkaline or acidic cleaning products. For use in food, beverage and packaging industries which are subject to strict hygienie regulations, a food-grade model is also available that additionally features food-safe lubrication and materials. With the same performance characteristics of the standard AKM permanent magnet motor range, this washdown synchronous motor is available in frame sizes 2 through 6, with several standard stack-lengths, also with a wide choice of winding, feedback and connection options.

The benefits of these industry-leading high performance motors are considerable. First there are certifications ranging from basic IP65 up to IP69K and FDA approval. Secondly there are thousands of model options as standard as well as severe washdown options. Then importantly, availability extends to all stainless options up to 300 and 17-4PH grade.
