Abstract

The invention provides a manufacturing method of a stator framework. The manufacturing method comprises the steps that 102, a bottom wall component is manufactured, and a side wall component of an integrally-formed structure is manufactured through an extrusion forming process; and 106, the bottom wall component is fixed to the first side of the side wall component, a first through hole of the bottom wall component and the interior of the inner ring wall of the side wall component form a shaft hole, P second through holes of the bottom wall component correspond to P sub-areas of the side wall component, and an annular wall is constructed in the corresponding sub-area of the hole wall of each second through hole. According to the manufacturing method of the stator framework, the welding steps are few, and the production efficiency of the stator framework can be effectively improved.

Description

technical field [0001] This article relates to motor equipment technology, especially a method for manufacturing a stator frame. Background technique [0002] As the power requirements of electric vehicles increase, the requirements for torque density and power density of new energy motors are also gradually increasing. The torque density of axial magnetic field motors is about 30% higher than that of traditional radial motors, and can output larger torque. [0003] Axial field motors are divided into: single rotor single stator structure, double stator single rotor Kaman structure, single stator double rotor Torus-NN structure, single stator double rotor Torus-NS structure, multi-disc structure. Among them, the single-stator double-rotor Torus-NS structure avoids the internal axial magnetic pull of the single-rotor single-stator structure, reduces bearing wear, and the stator of the single-stator double-rotor Torus-NS structure is located between the two rotors, and the ma...
