Abstract
According to an aspect of the present disclosure, a motor drive control device driving a motor using position information detected by one sensor includes: a current detection unit detecting a magnitude of a coil current flowing through a coil of the motor; a rotation position detection unit detecting a rotation position of the motor based on the position information; and a hunting determination unit determining, based on the magnitude of the coil current, the rotation position of the motor, and a driving command for driving the motor, whether or not the motor is in a hunting condition.
