There are many motor manufacturers, and the quality and price are also different. Although my country has already formulated technical standards for motor production and design, many companies have adjusted the design of motors according to market segmentation needs, and thus formed motors with different performances in the market. difference.
The motor is a product with very mature technology, and the production threshold is also low. In areas with developed industrial chains, there are many small workshop-style motor factories, but to achieve excellent performance and stable quality of the motor, a certain scale of motor is still required The factory is guaranteed.
The following is also the method to judge the quality of the motor
Silicon steel sheets are an important part of the motor, and together with copper wires account for the main cost of the motor. Silicon copper sheets are divided into cold-rolled steel sheets and hot-rolled steel sheets. The country has long advocated the abandonment of hot-rolled sheets. The performance of cold-rolled sheets can be reflected in the brand name. Generally, DW800, DW600, DW470, etc. are used. Ordinary asynchronous motors generally use DW800. Some companies use strip steel to manufacture motors, and the performance is significantly different.
The stator and rotor of the motor are die-cast from silicon steel sheets, and the length of the die-cast
