Abstract

See full text

The present disclosure is directed to a cooling system for a system, such as an electric power assisted steering (EPAS) system and the components of such system, such as a motor. The cooling system includes a temperature sensor coupled to an electric motor of the EPAS system, one or more fluid reservoirs, and a fluid transfer device coupled to the motor and to the first fluid reservoirs. The fluid transfer device extends along a length of the motor. The cooling system further includes a pump coupled to the fluid reservoir and the fluid transfer device, a control unit coupled to the sensor and the pump. The control unit is configured to activate the pump in response to temperature detected by the sensor being greater than or equal to a first threshold motor temperature. The pump transfers the fluid in the fluid reservoirs to the fluid transfer device for absorbing the heat of the motor. The fluid transfer device is configured to contain the transferred fluid.
