ABSTRACT:
A drive method for a brushless motor and a drive control apparatus therefor, in which control parameters are calculated by motor current control means (74in FIG.2) in accordance with the deviation between a target motor current value and an actual motor current value, a manipulated variable is computed by phase control means (76) on the basis of the calculated control parameters, an advance angle magnitude is computed from the relationship between a manipulated variable and an advance angle magnitude as designed and created beforehand, on the basis of the computed manipulated variable, and the value of the conduction phase angle of a drive circuit (72) as set on the basis of a motor current signal is corrected with the information of the computed advance angle magnitude.
