PURPOSE:To draw motor performance by changing the leading angle of a brushless motor using magnetic pole detecting elements. CONSTITUTION:A plurality of sets of magnetic pole detecting elements 41 and 42 are disposed at the positions where an arbitrary leading angle can be given; a logic circuit portion housing switching means for said elements is provided; and the leading angle is changed by switching the magnetic pole detecting elements used for the rotation of the motor. |
