Abstract

The invention belongs to the field of motors, and discloses a manufacturing method for a stator. The manufacturing method includes the following steps that according to the split manufacturing step of an iron core, a first split body and a second split body which can be axially stacked to form the iron core of the stator are manufactured; according to the winding step, stator windings are wound around the first split body and the second split body respectively, and a first winding coil and a second winding coil are formed on the first split body and the second split body respectively; according to the assembling step, the first split body where the first winding coil is wound and the second split body where the second winding coil is wound are axially stacked to form the stator. Large spaces are provided for winding performed on the first split body and the second split body, the winding efficiency of the iron core of the stator is improved, the slot fullness rate of the stator is increased, the material cost of the stator is lowered, and the performance of a motor is improved; meanwhile, the roundness precision of the stator is guaranteed, the first split body and the second split body do not need to be welded, and therefore the assembling process is simplified.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a manufacturing method of a stator. Background technique [0002] A traditional manufacturing method of the motor stator is as follows: First, the stator punches are punched out as a whole, and then the stator punches are laminated to form an integral stator core, and then the stator winding is wound on the integral stator core by a winding machine . The traditional manufacturing method of the stator has the following defects in specific applications: due to the limitation of the winding space requirements, the slot fill rate is not high, and the opening of the slot on the stator core needs to be designed larger, which affects the Improved motor performance. [0003] In order to solve the above-mentioned technical problems in the traditional stator manufacturing method, the prior art proposes two schemes for winding the stator core separately: [0004] 1) One solution is to completely se...
