ABSTRACT:
A motor controller for regulating the application of current to the windings of a motor in order to both control the actuation of the motor rotor and the braking of the rotor. The motor controller includes a speed control circuit regenerating a signal representative of the user-selected speed, a direction controller to signal if the motor is to be driven in the forward, reverse or oscillatory motion and a speed override circuit. There is also a current sensor for monitoring the current drawn by the motor, a brake controller and an energization circuit. The energization circuit regulates the application of a current to the motor to cause the rotation or braking of the rotor. When the motor is to be oscillated, each time the direction controller circuit transitions a FORWARD/REVERSE signal, the speed override circuit causes the energization circuit to momentarily apply energization signals to the motor based on the application of a zero-speed, user-speed signal. During such transitions, the current sensor sends a signal to the energization controller to make it appear that the motor is drawing in a large amount of current. Whenever the motor is operating at a speed higher than the user-speed, the brake controller causes the energization controller to apply braking current to the motor. However, if the rotor is not turning, the brake controller inhibits the assertion of the braking current.
