The Premotec permanent magnet stepper and synchronous motors combine high energy magnets in a cost effective “claw pole” design to give low operating temperature and a superior torque to size ratio. For the steppers, torques from 10 to 75 mNm and speeds from 300 to 1000 rpm are available, with a step angle of 7.5 degrees. All our steppers are available with unipolar or bipolar drive electronics. Rated torques for the synchronous motors run from 4 up to 33 mNm with a speed of 250 and 500 rpm (based on 50 Hz).
