Disc Magnet Stepper Motors by Portescap-Image

Portescap disc magnet motors provide exceptional dynamic performance unparalleled by any other small diameter stepper in the market. The unique thin disc magnet enables finer step resolutions in a given envelope, significantly higher acceleration and greater top speed than conventional steppers.

These high speed stepper motors excel in applications that require the precision of a Stepper and the speed and acceleration of a Brushless DC motor. Closing the loop provides a competitive advantage against a servo solution.
