摘　　要：异步电机在起动时,会产生较大的电流,对系统本身以及电网都会产生较大的影响,并造成了电能的浪费。当电机的负载低于额定负载的75%时,效率较低,造成了能源浪费。经过理论分析,设计了一种电机智能节能控制器,用于电机的节能、软起动和运行保护。The asynchronous motor is extremely widespread applied in industry and agriculture production. The motor produces a bigger electric current when starting, as well as the electrical network can have a tremendous influence to system itself, also wastes the electrical energy. When the motor load is lower than the rated load 75%, the efficiency was lower, has created the energy waste. After the theoretical analysis, has designed one kind of motor intelligence energy conservation controller, uses in motor energy conservation soft-start and the movement protection.
