ELMOTOR FOER DRIFT AV ARBETSMASKINER I SYNNERHET RAFFINOERER.

摘要

An electric motor for driving processing machines with slide bearings is designed without shaft shoulders in the regions of the slide bearings in order to achieve high axial mobility of the rotor shaft. However, so that the motor can be operated in the uncoupled condition briefly without axial displacement of the rotor, a rotor holding device is provided. The latter is fastened to the shaft end of the rotor shaft of the motor and comprises an antifriction bearing with axial load-carrying capability, whereby the rotor is given the necessary axial guidance.
