  • Electric motor with functional monitoring of the motor bearings
    Patent number: 9876410
    Abstract: The present invention relates to an electric motor, comprising a stator and a rotor that can rotate relative to the stator and that is mounted in bearing arrangements, and also comprising a motor housing and a vibration sensor to pick up vibrations that occur in the electric motor and that are caused by malfunctions of the bearing arrangements. The configuration provided here is that of an external-rotor motor. The stator has a bearing support tube that is connected at one end to a ring-shaped stator flange. Bearing arrangements are arranged at a distance from each other in the bearing support tube in the direction of a center longitudinal axis of the bearing support tube, in which a shaft of the rotor is supported. The vibration sensor is attached to the stator flange.
