Summary:Three-phase induction motors are the most popular and widely used machines in industry. An induction motor is essentially a constant speed motor, however in many applications there is a need of several speeds or continuously adjustable range of speed. The aim of this project is to apply a new method called binary technique for controlling the speed of induction motor. Binary technique is a newly developed class of mathematical synthesis tool for generating long sequences of ones and zeros. This binary technique can directly generate sinusoidal power output waveforms through use of inverter switching process. Binary technique can force any desired number of low harmonics precisely to zero by using fewest possible switching events. A microcontroller is used as a control device, which applies the binary technique to generate perfect sinewaves with higher efficiency, low distortion and low harmonics.
