Conventional and Solid State Speed Control of A.C Drives

A three phase induction motor is basically a constant speed motor so it‟s somewhat difficult to control its speed.

CONVENTIONAL & SOLID STATE SPEED CONTROL AC DRIVES

 

INTRODUCTION

 

          A three phase induction motor is basically a constant speed motor so it‟s somewhat difficult to control its speed. The speed control of induction motor is done at the cost of decrease in efficiency and low electrical power factor.

 

          To control the speed of three phase induction motor one should know the basic formulas of speed and torque of three phase induction motor as the methods of speed control depends upon these formulas.
