Embodiment Construction

[0020] refer to Figure 1 to Figure 3 An electric pump 10 provided by an embodiment of the present invention includes a pump body 20 , an impeller 30 accommodated in the pump body 20 , and a motor 40 that drives the impeller 30 to rotate.

[0021] The pump body 20 includes an inlet 22 and an outlet 24 . In this embodiment, the inlet 22 is arranged along the axial direction of the impeller 30 , and the outlet 24 is arranged along the circumferential direction of the pump body 20 . As the motor 40 drives the impeller 30 to rotate, fluid will be pumped into the pump body inlet 22 and out of the outlet 24 .

[0022] The motor 40 includes a stator 50 and a rotor 60 . The stator 50 includes a housing 52, a stator yoke 54 fixed to the housing 52, a plurality of stator teeth 56 arranged at intervals along the circumferential direction of the stator yoke 54, and a coil 58 wound on the stator teeth 56 and fixed to the center of the housing 52. Axis 59. The housing 52 includes a suppo...

Abstract

The invention relates to an electric pump. The electric pump comprises a pump body, an impeller contained in the pump body and a motor for driving the impeller to rotate; the motor comprises a stator and a rotor, the rotor comprises a rotor yoke and a permanent magnet which are fixed to the impeller, and the stator comprises a stator yoke, a plurality of stator teeth arranged in the circumferential direction at intervals and a coil wound on the stator teeth; the stator yoke is provided with a containing groove corresponding to each stator tooth, clamping claws are arranged on the two sides of the tail end of the containing groove, and after each stator yoke is inserted into the corresponding containing groove of the stator yoke, the clamping claws on the two sides of the tail end of the containing groove deform towards the stator teeth so as to fix the stator teeth into the containing groove. The electric pump is short in axial size, simple in structure, convenient to assemble and low in machining cost.

Description

【Technical field】 [0001] The invention relates to an electric pump, in particular to an electric pump using a disc motor. 【Background technique】 [0002] Conventional electric dishwasher pumps usually use radial clearance DC motors or induction motors. However, this type of motor has long axial dimension, low efficiency and complex structure. [0003] The invention aims to provide an electric pump with short axial dimension, simple structure and convenient installation. 【Content of invention】 [0004] To this end, the electric pump provided by the present invention includes a pump body, an impeller accommodated in the pump body, a motor for driving the impeller to rotate, the motor includes a stator and a rotor, and the rotor includes a rotor yoke and a permanent magnet fixed to the impeller , the stator includes a stator yoke, a number of stator teeth arranged at intervals along the circumferential direction, and coils wound on the stator teeth. The stator yoke is provi...
