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 6):
The motor driving device according to  claim 1 , further comprising:\n a rotation speed detection unit that detects a rotation speed of the motor, and wherein the control unit calculates a driving voltage of the motor so as to eliminate a deviation between a target rotation speed indicated by the command signal and an actual rotation speed of the motor detected by the rotation speed detection unit.
