LEAD ANGLE VALUE SETTING METHOD, MOTOR DRIVING CONTROL CIRCUIT, AND BRUSHLESS MOTOR |
摘要 |
A method for setting a lead-angle value of a motor drive control circuit is disclosed. The motor drive control circuit energizes and drives the windings of a motor with an energizing timing based on a stored lead-angle value. The method includes the steps of: rotating a rotor at a given rpm (step S102), energizing and driving the windings during the rotation at the given rpm with the lead-angle value being switched (step S110); calculating an average value of current amount that energizes and drives the windings (step S114); calculating a total value of consecutive multiple average values for each lead-angle value (step S120); finding a smallest total value among the total values, and setting a lead-angle value corresponding to the smallest total value as a stored lead-angle value (steps S122). |
