全塑换向器主要应用在高速旋转下的中小型直流电机、串激交流电机中,它可使电机结构紧凑、体积减小、重量轻、使用寿命长。我厂从1983年初开始对国内外全塑换向器的结构、生产方式等,进行了对比研究,终于在同一年底研制成功,并制造出样品,为我国填补了全塑换向器在制造工艺上的空白。1984年初小批生产并实际装车试用以及通过本厂的寿命试验、耐高温超速试验、耐低温试 It is mainly used in small and medium-sized DC motors and series AC motors under high-speed rotation. It can make the motor compact in structure, small in size, light in weight and long in service life. Since the beginning of 1983, our factory has carried out a comparative study on the structure and production mode of all-plastic commutator both at home and abroad. Finally, it was successfully developed at the end of the same year and made samples for our country to fill up the whole plastic commutator in the manufacturing process Blank on. In early 1984 a small batch of production and the actual loading trial and through the factory life test, high temperature speeding test, low temperature test
