Abstract
An electric motor run and brake control circuit for controlling alternating current to a three-phase motor in which the circuit is operated by a single logic level input signal. When the input signal is low, a run relay is closed and AC power is applied to the motor. When the input signal goes high, the run relay is opened and the motor is braked for a fast stop. A brake capacitor and charge resistor limit both the time during which braking current is applied and the repetition rate of braking cycles.
