ABSTRACT:
A dynamic braking system for a brushless motor where energization of the motor winding is achieved through a transistor bridge circuit wherein half of the switching transistors are connected to a positive supply and the remaining switching transistors are connected to a negative supply. Back biased diodes are connected across each of the switching transistors. Dynamic braking is achieved by rendering all transistors connected to one of the supply sources conductive at the same time.
