Motor stator producing process

Abstract

The invention discloses a motor stator producing process and aims to combine a producing process with a winding process without a high-precision automatic winding machine. The motor stator producing process comprises the following steps: 1, performing lamination processing so as to obtain a plurality of unit tooth pieces, and producing a plurality of stator tooth parts from the unit tooth pieces through a stamping process; 2, putting insulating parts into the stator tooth parts, and winding coils on the insulating parts; 3, assembling the stator tooth parts with the wound coils into a completestator, completing wiring of the coils, and sleeving connecting parts of the coils by insulating protection tubes; 4, integrally connecting two adjacent stator tooth parts through welding. The process has the beneficial effects that the stator is formed by assembling and welding modularized stator tooth parts, the stator tooth parts are already wound with coils before welding, and a high-precision automatic winding machine is not used, so that the cost can be reduced, the process difficulties can be reduced, meanwhile the stator space can be relatively reasonably utilized by the modularized stator tooth parts, and the size of a motor can be reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a manufacturing process of a motor stator. Background technique [0002] The stator is an important part of the motor. A common stator includes a stator core and a number of coils. The stator core is equipped with a number of stator teeth uniformly distributed along the circumference of the stator core for fixing the coils. Two adjacent Stator slots through which the coils can pass are formed between the stator teeth. [0003] The traditional stator manufacturing process is to process the complete stator core first, and then wind the complete stator core. Such a manufacturing process requires equipment like automatic winding machines to wind the stator core, while automatic winding The precision of the wire machine is high, and the winding method is complicated, which greatly increases the production cost of the stator. At the same time, the processing technology of the stator co...

[0003] The traditional stator manufacturing process is to process the complete stator core first, and then wind the complete stator core. Such a manufacturing process requires equipment like automatic winding machines to wind the stator core, while automatic winding The precision of the wire machine is high, and the winding method is complicated, which greatly increases the production cost of the stator. At the same time, the processing technology of the stator core and the winding technology are two independent processes, and the winding method is often affected by the shape of the iron core. , especially in terms of space size and space positioning, it puts forward high requirements for automatic winding machines
