Abstract:
Time information indicates time required for reflecting a speed control indicating value actually on the rotation speed of the motor, the speed control indicating value being read by a motor driving part and then, being reflected on the rotation speed of the motor by the motor driving part. the speed control indicating value is generated based on the time information and the rotation speed information. The speed control indicating value is read at a period which is based on the time information for actually driving the motor.
