PROBLEM TO BE SOLVED: To provide a drive control technology of a two-phase brushless motor, in which the motor can be rotated in a desired direction at starting by correctly recognizing the position of a rotor with respect to a stator accurately, without using Hall elements, and to determine wiring for starting conduction. SOLUTION: A pulse current is fed to two stator windings and the difference of kickback time caused by a subtle difference in the inductance between different windings which depend on the stationary position of the rotor is detected, thus recognizing the stationary position of the rotor. |
