Abstract :
The residual voltage in an induction motor under an interrupted power supply condition is considered. The electromagnetic shock at the end of the motor coil due to the excessive surge current and the mechanical impact due to the greater transient torque are investigated. The case when many induction motors are connected to a common bus is studied. Development of the analytical model and a method of decreasing rapidly the residual voltage are described. Simulation and experimental results are compared and show fair agreement.<>
