Abstract
A motor according to a disclosed embodiment includes: a first magnetic sensor that detects a rotational position of a rotor; a second magnetic sensor arranged at a rotation center of the rotor; a signal amplifier that amplifies a difference between a first signal, which is a signal output from the first magnetic sensor, and a second signal which is a signal output from the second magnetic sensor; and a pulse signal generation unit that converts an output signal of the signal amplifier into a pulse signal.
