Energy-saving Control System for AC Motors

摘要

When AC motor is operated in the light load or no-load, the power factor of AC motor is relatively low, so frequency converter is adapted to motor for energy-saving control, and the system increase the tracking function of the load on the basis of all the features of the conventional inverter. And it is able to real-time monitor to load changes of the motor through the microcontroller, online adjust the input power of the motor, so that the motor output power to match load, ensure that the energy consumption of the motor is reduced to a minimum extent in the entire load range.
