摘要
介绍了一种异步电动机的节能控制器的设计,通过实时检测电动机的电压、电流、功率因数,调节电动机的定子电压,使功率因数维持恒定,达到节能的目的,同时该控制器通过软件能对电动机进行保护。
A induction motor controller for energy-saving is introduced.In order to save energy, the power factor of the induction motor should be a const. It can be achieved through real-time detecting the voltage,current and power factor of motor stator to regulate voltage of the induction motor stator winding. At the same time, it can protect the motor with the system software..
