ABSTRACT:
An external rotor electric synchronous hysteresis motor. A stator provides a rotating electromagnetic field. The hysteresis ring is formed by a deep-drawn rotation symmetrical steel rotor pot having a jacket part for surrounding the stator coaxially and having a bottom part which is provided with a center hole. An end shield is cast into the bottom part of the rotor pot. A shaft is set into the end shield for supporting the rotary motion of the rotor pot.
The rotor pot can be deep-drawn from a steel plate into a molded pot blank, the molded pot blank can be machined to a finished rotor pot, the rotor pot can be heated to a temperature from 750.degree. C. to 900.degree. C. in an inert atmosphere and the jacket part of the rotor pot can be quenched by lowering the same into a cold oil bath under continuous rotation.
