摘要: A brushless motor drive device includes the following: an inverter circuit configured to energize and winding of a motor; current detection detect value winding; control unit rotation RC filter including resistor capacitor. The generate signal inverter; clock generation pulse be used as reference for operation period; output with changing frequency based on apply filter; AD converter connected capacitor circuit; AD-conversion-error calculation calculate conversion error circuit. calculates difference between produced in response input voltage AD-converted calculated from charging time
