摘要：
An electric motor includes a stator, a rotor, a rotor shaft and a pump. The rotor is disposed within the stator and separated from the stator by an airgap. The airgap inadvertently accumulates a fluid. The rotor shaft is connected to the rotor. The pump is configured to move the fluid out of the airgap.
