摘要： Disclosed are a device and a method for controlling a motor. According to a specific embodiment of the present disclosure, an input shaft of a motor is provided with a low-resolution absolute position detector and an output shaft of the motor is provided with a low-resolution absolute position detector having a resolution greater than or equal to a reduction gear ratio. An initial offset and an offset are defined accordingly, and a high-resolution output shaft absolute position is derived from a relational expression, which is defined by an input shaft absolute position received at a predetermined time interval, a derived offset, an output shaft absolute position, and the reduction gear ratio, such that it is possible to easily detect the high-resolution output shaft absolute position by using a low-price absolute position detector without the modification or addition of an actuator.
