An electric pump includes a pump housing, a rotor assembly, a stator assembly, an isolation sleeve, a heat dissipation plate and an electric control board. The pump housing defines a pump inner chamber; the pump inner chamber is partitioned into a first cavity and a second cavity by the isolation sleeve; the rotor assembly is disposed in the first cavity; the stator assembly and the electric control board are disposed in the second cavity; the isolation sleeve comprises a bottom portion; at least a portion of the heat dissipation plate is disposed between the electric control board and the bottom portion; at least a portion of the bottom portion and at least a portion of the heat dissipation plate are in direct contact, or are filled with thermal silicone grease or thermal silica therebetween, or are provided with a thermal patch therebetween.

Electric pump

A stator assembly includes a stator core. The stator core includes a yoke and teeth. Each of the teeth includes a neck and a tip. The neck includes a first stacking portion, a second stacking portion, a first plane and a second plane. The first stacking portion and the second stacking portion are arranged opposite to each other, and the first plane and the second plane are arranged opposite to each other. The first stacking portion and the second stacking portion are formed by stacking silicone steel sheets of the neck, and the first plane and the second plane are outer surfaces of silicone steel sheets at two terminal ends of the neck in a stacking direction.

Stator assembly, electric pump having stator assembly, and method for manufacturing stator assembly

An electric pump is provided according to the application, which includes a housing, a shaft, an impeller, a rotor assembly, a stator assembly and an inner chamber. The shaft, the impeller and a rotor are arranged in the inner chamber. The housing includes a first housing, a partition and a second housing, and the partition divides the inner chamber into a wet chamber and at least one dry chamber. The partition includes a first side wall, a first bottom, a second side wall and a second bottom. The second side wall isolates the rotor assembly and the stator assembly. An outer peripheral surface of the second side wall is provided with reinforcing ribs, and the reinforcing ribs improve the strength of the second side wall.
