Abstract :
Focuses on developing a methodology for control of speed of a single phase induction motor (SPIM) by using a binary rate multipliers (BRM) technique and a programmable multi-frequency technique (40-80 Hz) in order to control suitable energy supply to the motor. If voltage and current are known then power can be calculated by using the vector space method. The results (torque and speed) are fed back to two proportional-integral (PI) controllers in order to select BRM patterns that can be generated in up to 256 forms. Power factor at no load and full load is also increased. Thus, higher efficiency is achieved
