KressTM Technology
At the intersection of magnetics, power electronics, and networking

Kress Technology develops new technology at the intersection of magnetics, electronics, and networking.  We have built, analyzed, tested, and improved 28 prototype motor and drive systems to date, and we intend to keep pushing the capabilities of new materials and new software in the development of integrated, networked motor systems.

Field-replaceable stators 

Variable speed and torque over a wide range

Easily reconfigured for application-specific design 




Replaceable stator demonstration at Motor and Drive Show (click here for more pictures from the Show)

The magnetic and mechanical parts of the 10 horsepower prototype Motor and Drive System consist of two rotor disks and 12 individual stators housed in a cylindrical frame.  Each stator is laterally positioned between salient points on the rotor disk.  The stators are individually removeable and are field replaceable.

The Drive uses IGBT modules to switch the current to the right stator at the right time. Additionally, the Drive monitors sensors in the motor, including shaft speed and position, temperature, vibration, and flux density. New developments in power electronics support the voltage / current levels required for higher horsepower motors.

The Kress Motor and Drive System connects to factory automation systems or to a local laptop via a standard RJ-45 EtherNet connection or a RS-232 port.  Kress Technology is interested in working with factory automation systems providers to further develop the data exchange protocols for integration into wired or wireless networks.
