Abstract:
Based on an output signal, among a plurality of switching elements, an element control part outputs a PWM signal having a maximum duty ratio to a pair of switching elements that drive a first coil among a plurality of coils to a high level, outputs a PWM signal having a minimum duty ratio to a pair of switching elements that are connected to each other in series and that drive a second coil among the plurality of coils to a low level, and outputs a PWM signal having a medium duty ratio between the maximum duty ratio of the PWM signal and the minimum duty ratio of the PWM signal to a pair of switching elements that are connected to each other in series and that drive a third coil among the plurality of coils.

Claim (Index 1):
A motor drive apparatus that supplies a current to a plurality of coils and that rotates a rotor, the motor drive apparatus comprising:\n a plurality of switching elements that turn on or turn off respective current supply routes connected to the plurality of coils; a plurality of detection sensors each of which is provided at a phase different from one another in a rotation direction of the rotor and which are configured to detect a phase in a rotation direction of the rotor and generate an output signal; and an element control part that turns on or turns off the plurality of switching elements individually based on the output signal, wherein, based on the output signal, among the plurality of switching elements, the element control part outputs a PWM signal having a maximum duty ratio to a pair of switching elements that drive a first coil among the plurality of coils to a high level, outputs a PWM signal having a minimum duty ratio to a pair of switching elements that are connected to each other in series and that drive a second coil among the plurality of coils to a low level, and outputs a PWM signal having a medium duty ratio between the maximum duty ratio of the PWM signal and the minimum duty ratio of the PWM signal to a pair of switching elements that are connected to each other in series and that drive a third coil among the plurality of coils.
