摘要
针对拖动离心风机的电动机存在功率配套过大、电能浪费的情况,采取变极降速的办法,减少轴功率。通过改造实例,介绍了电动机变极方案的实施和节能效果,该方案值得推广。
In order to solve the high match power and electrical energy waste problem of the centrifugal fan mo-tor,the pole-changing method was proposed to reduce shaft power.The implementation method of pole-changing and energy saving effect had been pointed out and it had broad market prospects.
