ABSTRACT:
A set of circuits for controlling the slew rate of a driving transistor in a rotating three-phase DC motor having a "Y" configuration of coils. The slew rate is reduced when the rotational speed of the motor is low. The slew rate is controlled by controlling the voltage applied to a control terminal of the driving transistor. The voltage applied to the control terminal of the driving transistor is selected in response to a control signal that is indicative of the speed of the motor.
