Abstract
A motor control unit includes a sensing unit and a driver unit. The sensing unit includes a sensor magnet to rotate in synchronization with a rotation of a rotor included in a motor, and a first sensor element and a second sensor element to convert a signal caused by a rotation of the sensor magnet into a digital signal. The driver unit controls the motor based on output signals of the elements. The sensor magnet includes a first magnetization belt and a second magnetization belt where a plurality of magnetic poles is arranged in a peripheral direction of the rotor. The belts are concentrically disposed to cause arrangements of the magnetic poles to be shifted by a predetermined angle in a peripheral direction. The elements are arranged in a radial direction of the rotor.
