How Complicated Is The Motor Manufacturing Process?

- Nov 13, 2018-

Motor manufacturing process content:

1. Machining process: including rotor machining and shaft machining.

2. Iron core manufacturing process: the manufacture of punched sheets including magnetic pole cores and the lamination of punching sheets.

3, winding manufacturing process: including coil manufacturing, winding embedded and insulation treatment (including short-circuit ring welding).

4, squirrel cage rotor manufacturing process: including the rotor core stacking, rotor die casting.

5, motor assembly process: including the riveting of the bracket assembly, the main and auxiliary stator riveting and assembly of the motor.

In the manufacture of motors, the same design structure and the products made from the same batch of raw materials often have a very different quality (the difference in iron consumption can reach 40%, and the insulation resistance of coil insulation can reach 80%). The service life is several times different.) Therefore, in addition to the raw materials, purchased parts, and external components, an important reason is that the process is not perfect or is not carefully processed according to the process rules. Such as: rotor cast aluminum, rotor processing, bracket riveting, stator short-circuit ring riveting, etc., the defects caused in the manufacturing process, not easy to detect when parts are inspected, if the defective parts are used in the product Going up will result in reduced product quality and reduced service life. In the current production of motor types, the scale of production is getting larger and larger, the degree of automation is getting higher and higher, and the requirements for the operational reliability and quality stability of the motors used are becoming more and more strict. Therefore, the use of reasonable process plans and process methods, and careful implementation, is the main conditions necessary to ensure the quality of the motor. The production volume is getting larger and larger. The more special equipment and special tooling are used, the more detailed the process work, the higher the production efficiency, the lower the product cost and the more stable the quality.

Process work is the bridge between product design and workshop production. The process work is to convey the intention of product design to the relevant departments through the form of process documents, such as: process cards, process codes, process cards, product process flow charts, etc.
