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.

Abstract: An electric pump is provided, which includes a housing, a shaft, a rotor assembly and a stop assembly. 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 and a second stop, the first stop is fixed with respect to a second portion of the shaft, and the second stop is fixed with respect to a first portion 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.

Abstract: An electronic pump is provided, which includes a rotor assembly. The rotor assembly includes an impeller and a rotor which are separately injection-molded respectively. The material for injection-molding the rotor includes a magnetic material, and the material for injection-molding the impeller does not include a magnetic material. The impeller includes a first fitting portion, the rotor includes a second fitting portion, the impeller and the rotor are cooperated by the first fitting portion and the second fitting portion, and the impeller and the rotor are fixed with respect to each other by a fixing device. In this way, the impeller and the rotor may be made respectively by different materials, and an ordinary plastic material may be employed for the impeller, which may reduce the cost of manufacturing material of the rotor assembly.
Abstract translation: 提供了一种电子泵，其包括转子组件。 转子组件包括分别注塑的叶轮和转子。 用于注射成型转子的材料包括磁性材料，并且用于注射成型叶轮的材料不包括磁性材料。 叶轮包括第一装配部分，转子包括第二装配部分，叶轮和转子由第一装配部分和第二装配部分配合，叶轮和转子通过固定相互固定 设备。 以这种方式，叶轮和转子可以分别由不同的材料制成，并且可以使用普通的塑料材料用于叶轮，这可以降低转子组件的材料制造成本。
