PROBLEM TO BE SOLVED: To prevent decrease in a linearity characteristic of a motor.SOLUTION: A driving apparatus is configured to switch states in one modulation period so as to include a conductive state in a first drive direction, a conductive state in a second drive direction having a different polarity than the conductive state in the first drive direction, and a ground state, at least when a motor output including a case where a duty ratio of a PWM control is at zero is in a low output region, in which the duty ratio is changed by changing periods of the respective states. |
