Experiment on blueing technique of low-carbon steel for electromotor stator of micro electric pump

Compared to silicon steel sheet, low-carbon steel has its advantages of rich resources and low price. In order to reduce cost of micro eleetromotor of micro electric pump used in pump industry, an ex- perimental study of the application of low-carbon steel instead of silicon steel sheet on the electromotor of micro electric pump was carried out. The mechanism of annealing and blueing was analyzed. A process of annealing and blueing treatment for stator of low-carbon steel was designed. In order to make a comparative analysis of the main technical specifications such as no-load and full-load current, efficiency, tem- perature rise, and power factor of electromotor between low-carbon steel stator and silicon steel stator, a performance test of electromotor of electric pump installed with the stator of low-carbon steel was conduc- ted. The experimental results show that the electromagnetic properties of low-carbon steel sheet after an- nealing and blueing treatment reach the technical specifications of silicon steel, so it is workable to be taken as alternative material for silicon steel sheet for stator of electromotor of motor pump.
