摘要： 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.

摘要： An electronic pump includes a second housing, a rotor part, a stator part and a circuit board. A pump chamber is separated by a partition into a wet chamber allowing a working medium to pass through and at least one dry chamber where there is no working medium passing through, and the rotor part is arranged in the wet chamber. The electronic pump further includes a shaft, a sunken portion is formed at a top portion of the partition, and the shaft and a bottom of the sunken portion are fixed by injection molding. A portion where the rotor part is in contact with the shaft is a cooperation portion of the rotor part, and the cooperation portion is arranged in a cavity of the sunken portion.
