目前,冰箱电机烧损情况较为严重。据不完全统计,1976年因电机烧损而需修理的冰箱占电冰箱修理总数的27％,占压缩机修理数的50％,给国家造成很大浪费,用户也很不满意。本文就电机烧损原因,提高和改善电机起动性能的途径等进行一些讨论,这是我们做了大量试验后得到的一些认识。文中提及的电机均系滑管式封闭压缩机用93瓦单相两极感应电动机。一、电机烧损原因电机烧损多半是因电机起动困难而强行起动所致。冰箱电机在起动时流过起动绕组
At present, the refrigerator motor burn more serious. According to incomplete statistics, the number of refrigerators to be repaired due to motor burn in 1976 accounted for 27% of the total number of refrigerator repairs and 50% of the number of compressor repairs, which caused great waste to the country and was also not satisfied by the users. This article discusses some of the causes of motor burn-in, ways to improve and improve motor starting performance, and some of the insights we have gained from extensive testing. The motor mentioned in this article is a 93-watt single-phase two-pole induction motor for a slide tube-type hermetic compressor. First, the cause of motor burn Motor burn mostly due to motor starting difficulties caused by forced start. The refrigerator motor flows through the starting winding at start-up
