Abstract:
API duty calculation unit of a microcomputer that performs control at a predetermined control period calculates a duty ratio of a voltage applied to a coil of a motor from a target rotation speed and an actual rotation speed calculated by a number-of-rotation information unit. The PI duty calculation unit generates a rectangular wave signal having a period according to one frequency selected from plural predetermined frequencies together with the start of one control period and indicating the calculated duty ratio, and outputs the rectangular wave signal to a PWM duty calculation unit. The PWM duty calculation unit generates a PWM signal for controlling an inverter circuit based on the rectangular wave signal output by the PI duty calculation unit and position information of a rotor of the motor calculated by an electrical angle position information unit.

Claim (Index 1):
A motor driving device comprising:\n a driving unit that includes a plurality of switching elements, each of which is on or off controlled by a pulse width modulation signal, and that drives a motor with a driving voltage according to an on or off state of the plurality of switching elements; and a control unit that repeatedly operates at a predetermined cycle, that generates a pulse width modulation signal based on a command signal and a signal selected from a plurality of predetermined signals having different frequencies at the start of operation, and that controls the on or off state of the plurality of switching elements of the driving unit by using the generated pulse width modulation signal.
