What are the quality of the motor requirements?

Main factors affecting the quality of the motor are: the material quality, quality system, personnel quality. Composition: 1, motor rotor shaft, fan, and junction box, etc. Motor material use ratio of special steel, from copper loss, iron loss, mechanical loss three aspects to reduce energy loss 20% 50%, thus greatly improve the overall efficiency. An expected service life of the machine is more than twenty years. Winding is easy to the cause of motor damage. After the long running insulation system including winding copper wire enameled began to damage, and generate a short-circuit. High-quality motor can not by new winding severely reduces the efficiency of the machine. The lower the operating temperature of the motor, the longer the insulation system life. Normally when motor running load, temperature can be reduced to 60 80° C, and low-quality motor can be more than 90 & deg; C。 In theory, operating temperature lower 10 - 15° C, winding can prolong life and come on time. 4. : the key components of the motor bearing is prone to failure of machine parts. 5. The stator is made up of a silicon steel sheet pile, it is a kind of low loss with insulation stalloy, the silicon steel sheet must be consistent performance, and as thin as possible, to make the magnetic field strength reached the maximum.
