Motor stator and winding method of motor stator

Abstract

The invention discloses a motor stator and a winding method for the motor stator, belonging to the technical field of electromechanical. The motor stator includes a silicon steel sheet, a motor stator insulating sheet installed on the front and rear surfaces of the silicon steel sheet, a motor stator winding insulating ring located on the motor stator insulating sheet, and copper wires wound on the motor stator winding insulating ring and the silicon steel sheet. The copper wire of the outer-wound motor stator of the present invention has a good heat dissipation effect; at the same time, the outer-wound motor stator does not form mushroom-shaped wire wraps at both ends, which can effectively reduce the axial length of the motor rotor and increase the rigidity of the motor rotor , greatly improving the mechanical properties of the motor rotor.

Description

Technical field: [0001] The invention relates to a motor stator and a winding method for the motor stator, belonging to the field of electromechanical technology. Background technique: [0002] In the existing centrifugal blower, the motor rotor and the motor stator are usually installed. The winding method of the copper wire in the existing motor stator is an inner winding type. The copper wire in the motor stator made by this method is concentrated in the silicon steel sheet and If the contact area with the air is small, the heat dissipation effect of the motor stator is not good. At the same time, the motor stator made by the inner winding method often forms a large mushroom-shaped wire package at both ends of the motor stator, which will make the motor rotor The axial length increases, which greatly reduces the mechanical properties of the motor rotor. [0003] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Invention co...
