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 electric pump (100) is provided, which includes a housing (20), a shaft (40), a rotor assembly (50)and a stop assembly (90). The shaft is fixed to the housing, the rotor assembly is rotatable about the shaft, and the rotor assembly is sleeved on the shaft. The stop assembly is configured to limit the position of the rotor assembly in the chamber. The stop assembly includes a first stop (1) and a second stop (2), the first stop is fixed with respect to a second portion (402) of the shaft, and the second stop is fixed with respect to a first portion (401) of the shaft. No relative movement occurs between the stop assembly and the shaft, which reduces the abrasion between the stop assembly and the shaft resulted from friction, and facilitates improving a service life of the stop assembly.
