ABSTRACT:
Motor control system for reversible series DC electric motor having improved dynamic braking performance for smoothly, rapidly, and consistently stopping the motor armature rotation so that any operated devices are similarly stopped at a predetermined location. The control system uses a bridge conformed like a full-wave rectifier together with a series of switches having open and closed positions to control the direction of current through the armature. The current through the motor field winding is always in the same direction. Provision is made to insure operation of a complete cycle once the system is initially energized and the switches which control the direction of current through the armature are protected from arcing upon opening.
