Electric motor as shaft drive arrangement, has through bore machined into housing centrally to motor rotation axis; shaft is inserted in hollow shaft mounted in bore and joined to rotor

摘要

The device has a housing (2) for a stator (3) and a rotor (4). A through bore is machined into the housing centrally with respect to the rotation axis of the motor. A hollow shaft (11) is mounted in the bore and joined to the rotor either directly or via intermediate elements. The hollow shaft and the shaft to be driven, which is inserted into it, interact by friction or shape-locking in the drive state.
