  • Brushless direct current motor with minimized current ripple and method
    Patent number: 5191269
    Abstract: A brushless direct current motor with minimized current ripple and a method is disclosed. The motor system includes commutation current control for controlling the rate of turn-off of the current flowing in the phase being turned-off while simultaneously controlling the rate of turn-on of the current flowing in the phases being excited. This minimizes torque ripple in the motor.
