Abstract
An electrically driven pump includes a first housing and a second housing, and the first housing and the second housing are fixed to form an impeller chamber for receiving an impeller. The second housing and a rear housing are fixed to form a first receiving chamber for receiving a motor assembly; and the motor assembly includes a stator and a rotor, the rotor is arranged in an inner cavity enclosed by the stator, and the rotor drives the impeller to rotate. An electronic control unit is cooperated with the motor assembly, and the electronic control unit controls the operation of the motor assembly. The electrically driven pump includes a cooling passage for accommodating a working medium, and the working medium in the cooling passage may exchange heat with the electronic control unit, thereby facilitating improving the service life of the electrically driven pump.
