摘要
异步电机的电流大小和电机消耗的功率随负载的轻重而改变,利用电磁调速、恒转矩负载等节能方法,对变频异步电动机节能进行了估算,分析采用变频器对交流异步电动机进行调速控制,可以节省可观的电能。
The current of asynchronous motor and the power consumption of motor increases with load change. The variable frequency asynchronous motor was estimated by the use of energy-saving method of electromagnetic speed control and constant torque. A large amount of electric energy could be saved by using a suitable frequency converter for AC asynchronous motor speed control.
