Abstract

Three phase induction motors with squirrel cage rotors are widely used for industrial applications of all kinds. These motors are very rugged, simple and reliable by design. Speed control by application of a 3-phase voltage of variable frequency is the method of choice, if efficient operation is desired. This paper describes the results of a two semester senior laboratory project aimed at the design of a voltage inverter for the speed control of a 3-phase induction motor. A 4-pole induction motor was controlled to operate between 50 RPM and 8000 RPM using this inverter. The paper includes a detailed description of the design and performance studies performed using a dynamometer. An equivalent circuit of the induction motor including the effects of the squirrel cage rotor construction has been simulated on a LOTUS 1-2-3 spreadsheet.
