Abstract
A motor control apparatus for controlling a motor based on an output from a sensor includes a storage unit storing a value according to an excitation power supply to excite the sensor, a PWM output unit outputting a PWM output signal having a pulse width modulated to have a duty ratio corresponding to a value stored to the storage unit, and a filter input with the PWM output signal from the PWM output unit. The sensor is supplied with the excitation power supply based on an output from the filter.
