Abstract
Provided are an apparatus and method for controlling a ripple current sensing motor. An apparatus for controlling a ripple current sensing motor may include a first shunt resistor having one end connected to one end of a motor and the other end of the first shunt resistor connected to a ground, a second shunt resistor having one end connected to the other end of the motor and the other end of the second shunt resistor connected to the ground, a first amplifying circuit amplifying a first signal from one end of the motor, a second amplifying circuit amplifying a second signal from the other end of the motor, and a detector detecting a rotation amount and a rotation direction of the motor using a change in voltages of a first detection signal from the first amplifying circuit and a second detection signal from the second amplifying circuit.
