Three phase induction motor produces severe starting torque pulsations. This causes shocks to the driven equipment and damage to the mechanical system components. In this method a novel method for starting of induction motor is proposed. The scheme depends on initial switching instances at which each phases of motor terminals are connected to the supply. A mathematical model for a three phase induction motor is developed in matlab/simulink and observed the effectiveness of the system in the elimination of torque pulsations. Hardware is implemented with an AC voltage controller using skt 24/12e thyristors. The gate control is provided with 89C51 microcontroller and the simulation results are verified through the hardware.
