Inverter-Fed Induction Motors

Induction motors were intended to be fed from a constant magnitude AC mains power supply at a fixed frequency of 50 or 60Hz. They have gained considerable popularity since their earliest use, due to the advantages they present compared to DC motors with respect to cost and robustness, as well as because of the quasi-absence of maintenance requirements. However, when fed by a constant frequency input, their speed cannot easily be regulated. Induction motors are well-suited for quasi-fixed-speed operation, which is why DC motors have for decades been favored in variable-speed drive applications. Speed regulation requires induction motors to be fed through a power supply of adjustable voltage and frequency.
