Torque limited synchronous motors

Range of application:

For control and actuation of devices in machine construction and precision engineering where compact dimensions, high torque, constant speed, and mechanical overload protection are required.


Torque limited motors are synchronous motors with integrated hysteresis slip coupling. The motors are 100% stall-resistant. A slip coupling connects the rotor shaft with the output shaft. If the torque limit is exceeded, the output shaft will stop; however, the rotor shaft will continue rotating. The coupling operates contactless and therefore is not subject to wear and tear. The torque limit is preset and fixed.
