Speed of an electrical motor is largely dependent on the AC Drive used. As such, it is crucial that such drives are chosen wisely as picking the right quality AC Drive will maximize energy savings as well as enhance the process control. Use of such drives also leads to reduction in the mechanical stress on motor control applications. These drives also popularly known by names like adjustable speed drives, variable frequency drives, frequency converters, etc., can bring large scale reduction in energy consumption when used for suitable applications.
