单相电容启动异步电动机节能问题研究
Research on economizing energy of asynchronous motor with the single-phase capacitor starter
【摘要】 针对单相电容启动异步电动机运行时功率因数比较低的问题,提出电动机启动并转入运行时,在其主绕组并联适当的电容器的方法,减少或省去电源对电动机提供无功电流,以减少线路损耗,提高电源功率因数,提高电源设备容量的利用率。
【Abstract】 The paper provides a novel method which combines column with shunt capacitor when motor is started and turn to be operated.This method could reduce reactive current,reduce circuitry loss and improve power factor.
