Abstract
The apparatus includes a motor control circuit including an amplifier with an inductance compensation circuit responsive to a motor, such as a switched reluctance motor, having inductance variations. The inductance compensation circuit includes at least two inductance compensation values and switching means for alternatingly coupling and decoupling at least one of the inductance compensation values from the inductance compensation circuit providing at least first and second inductance compensation for driving the motor in response to variations in the inductance of the motor.
