摘要
为了能安全合理地应用异步电动机交流调压调速的方法,从功率损耗的观点出发,分析了异步电动机在不同性质负载时的转差功率,表明了交流调压调速方式只适用于风机、水泵类负载,而不适用于恒转矩负载。
For the sake of ability the safety reasonably applies a diilerence step, me electric motor communicates to adjust to press to adjust soon of method, the standpoint exhausting from the power sets out and analyzed a difference step electric motor at not the congeniality load of turning and differing power, expressed to communicate to adjust to press to adjust soon way is applicable to breeze machine, water pump load, but unwell used for constant torque of load.
