Abstract:
An electrical machine with torque limitation which is only slightly larger structurally than an identical machine without torque limitation and is thus as compact as possible has a stator with windings and a rotor supported movably relative to the stator, recesses distributed over the circumference and extending axially are present on the rotor surface, and a driver, located coaxially relative to the rotor and extending axially, is located in the air gap between the rotor and the stator, and exciter magnets on the upper driver face toward the stator and driver magnets on the inner driver face toward the rotor are located in such a way that upon rotation of the driver, the rotor is likewise capable of being set into rotation as a result of the rotary field generated by the windings and by the driver magnets.
