The winding with seriously aged insulation should be exchanged. 4. The induction motor sound is abnormal. In two-phase operation, there is a buzz sound. Restart the motor after shutting down. If the motor doesn’t rotate in two-phase operation, find the reason for phase loss and eliminate it. The three-phase current is unbalanced.

In today's world where requirement of electrical energy is considerably increasing due to automization, innovations, huge productions and many other factors, while on the other hand the resources for generating this energy are

Most electric motors are designed to run at 50% to 100% of rated load. Figure 3 Relationships Between Power, Current, Power Factor and Motor Load.

This manual, Three-Phase Motor Drives, introduces the student to the operation of three-phase, variable-frequency induction-motor drives. Modern implementation of these drive systems allows better motor control which translates into improved power efficiency and significantly reduced power consumption.
