Problems solved by technology

[0003] The stator assembly and the rotor assembly of the automotive electronic pump are completely isolated by the isolation sleeve, which avoids the liquid leakage problem of the traditional motor-type brushless DC water pump, but the coaxiality of the stator assembly and the rotor assembly isolated by the isolation sleeve is difficult to ensure. There is a loss of magnetic field energy when the electronic pump is running

Abstract

The invention provides an automobile electronic pump. The automobile electronic pump comprises a first shell body, a second shell body, a rotor assembly, a stator assembly and a circuit board. The electronic pump comprises a pump shaft which comprises a first section, a second section and a third section, wherein the first section is located in a circulation cavity, the second section is fixed to an isolation sleeve, and the third section is located in a containing cavity. The rotor assembly can rotate around the first section of the pump shaft, and the stator assembly is fixed to the third section, so that the rotating axis of the rotor assembly, the center line of the stator assembly and the central axis of the pump shaft are basically coincident; in this way, the coaxiality of the stator assembly and the rotor assembly can be ensured, and the magnetic field force is improved.

Description

【Technical field】 [0001] The invention relates to a centrifugal pump, in particular to a vehicle electronic pump. 【Background technique】 [0002] In recent decades, the automobile industry has developed rapidly. With the performance of automobiles, it is developing in the direction of safer, more reliable, more stable, fully automatic, intelligent, environmentally friendly and energy-saving. Automotive electronic pumps have gradually replaced traditional mechanical pumps and are widely used in automotive heat dissipation circulation systems. The automotive electronic pump has the advantages of no electromagnetic interference, high efficiency and environmental protection, and stepless speed regulation, which can well meet the requirements of the market. [0003] The stator assembly and the rotor assembly of the automotive electronic pump are completely isolated by the isolation sleeve, which avoids the liquid leakage problem of the traditional motor-type brushless DC water p...
