ABSTRACT:
An electric motor, for instance for a hydraulic elevator, is entirely immersed within a liquid such as oil, and is provided with a flywheel. A drawback of this kind of electric motor is that the flywheel, rotating in oil, brakes the rotation of the motor. In the present electric motor the flywheel is enclosed in a housing and an air pipe extends to the housing so that by action of centrifugal force air is drawn into the housing, and liquid in the housing escapes from the housing through a discharge aperture when the motor starts.
