  • Device and method for driving a motor
    Patent number: 7112937
    Abstract: A motor control device having memory for storing data indicative of a control mode and a pulse width modulation (PWM) value and logic that applies the pulse width modulation value to a voltage provided to a motor if the data indicative of the control mode indicates voltage mode. The logic further controls the voltage applied to the motor based upon a motor set point value representative of the data indicative of the pulse width modulation value when the data indicative of the control mode indicates current mode.
