Motor blocking stator structure, motor stator and motor

Abstract

The invention discloses a motor blocking stator structure, a motor stator with the motor blocking stator structure and a motor. The motor blocking stator structure includes a plurality of mutually independent stator punching sheets which are stacked together, wherein the plurality of stator punching sheets are fixed together through coiling. In the motor blocking stator structure, the plurality ofstacked stator punching sheets are fixed together through coiling; no other fixed structures are arranged among the plurality of stator punching sheets; and the stacked stator punching sheets are fixed together only through winding of coiling; and the plurality of blocking stator structures are fastened and fixed through fastening rings to realize firm fixing of the overall motor stator. The motor blocking stator structure can effectively reduce the iron core loss of the stator core, can improve efficiency of the motor and can reduce temperature rise of the motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a block stator structure of a motor, a motor stator and a motor provided with the block stator structure. Background technique [0002] The traditional motor stator core generally adopts a monolithic or segmented splicing structure. Whether it is an integral or block splicing structure, most of the stator punchings are fixed together by welding, buckle riveting, buckle point riveting, etc. to meet the technical needs. For example, in the buckle riveting, the buckle riveting needs to be buckled at the outer diameter of the stator core, so that there is a large height difference between the inner and outer diameters of the stator punching; while welding (such as laser welding or argon arc welding), buckle point riveting The insulation of the silicon steel sheet is destroyed, which increases the iron consumption and temperature rise of the motor. In addition, welding will damage th...

For example, in the buckle riveting, the buckle riveting needs to be buckled at the outer diameter of the stator core, so that there is a large height difference between the inner and outer diameters of the stator punching; while welding (such as laser welding or argon arc welding), buckle point riveting Destroying the insulation of the silicon steel sheet increases the iron loss and temperature rise of the motor

In addition, welding will damage the insulation structure of the silicon steel sheet, and the iron loss of the stator core will increase, which will increase the temperature rise of the motor; the buckle point riveting will be sharply worn due to the stress concentration due to the small buckle point. Die life is greatly reduced
