Problems solved by technology

[0004] The purpose of the present invention is to provide a new block-type stator core, stator and motor, and solve the stator core winding difficulties existing in the prior art by splicing and connecting each of the circular-arc iron core blocks. The slot full rate is not high and the slot width is large at the same time.

Abstract

The invention relates to the technical field of motors, in particular to a block type stator core, a stator and a motor. The block type stator core provided by the invention comprises multiple arc iron core blocks which are connected end to end; two adjacent arc iron core blocks are connected by virtue of a sliding splicing mechanism; each arc iron core block comprises the outer ring arc slab, theinner ring arc slab and the wrapping post connected between the outer ring arc slab and the inner ring arc slab; and each arc iron core block respectively carries out wire winding and then is splicedand connected, and compared with the traditional whole circle iron core, a wire winding operation on each arc iron core block is easy, filling ratio can be increased, width of a notch can be reduced,and cogging torque can be beneficially reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a block-type stator core, a stator and a motor. Background technique [0002] In the permanent magnet motor, the performance of the motor is affected by the stator winding and the width of the stator slot. The traditional full-circle stator structure is: two concentric rings are connected by multiple winding posts set at intervals, and the gap between the two rings is The spacing between the winding posts and the winding posts are set up as winding slots, the two rings and the winding posts are the iron core of the stator; the copper wires pass through the winding slots on both sides of the winding posts in sequence and are wound on the winding The stator is completed by winding each winding post between the two rings with copper wire. The manufacturing method of the stator core of this kind of structure is that a plurality of full-circle laminations are stamped into a columnar w...
