Abstract :
The rapid deceleration of induction motors from relatively high speeds to standstill by the application of constant potential to the terminals is considered in this paper. Applications in which d-c braking of induction motors is desirable are mentioned, and the fundamental principles involved in this method of braking are considered. The characteristics of the speed-torque curve are derived from these principles. The practical application of d-c braking is demonstrated by the results of extensive tests, and a simple means of calculating the approximate values of current and wattage necessary for braking is included.
