发明名称 Electric motor
摘要 An electric motor includes an armature shaft which is mounted in at least one floating bearing. The floating bearing comprises a bearing inner ring, which is positioned on the armature shaft, a bearing outer ring, which is received in a bearing seat, and a fluid pump for a vehicle fluid system having the electric motor. Lubricant disposed between the armature shaft and the bearing inner ring forms a hydrodynamic lubricant film and generates a constant relative movement between the armature shaft and the bearing inner ring.
