ELECTRIC MACHINE, IN PARTICULAR OF A PUMP UNIT

摘要

The invention relates to an electric machine (1), comprising a stator (11) and a rotor (10) in a machine housing (7), wherein said rotor is disposed on a motor shaft (4) supported on the B side in a bearing unit (14) which has a ball bearing arrangement (21, 22) and is disposed radially elastically and axially movably within the machine housing (7). The electric machine (1) is preferably coupled on the A side without bearings via a rigid shaft coupling (12) to a working machine (2), in particular to a hydraulic pump.
