<p>A control device of a three phase brushless motor is presented to remove mismatch of conducting transition timing, due to the error of the position of a position sensor and the error of the magnetization position of a rotor, without complex adjustment. According to a control device of a three phase brushless motor(10), the three phase brushless motor has a plurality of stator coils around a rotor. A switch circuit(110) switches conduction for each stator coil. A position detection signal generation device(40) includes three position sensors and generates a position detection signal sequentially in correspondence to the rotation position of the rotor. A control circuit(120) calculates plural conducting transition timings for each stator coil by receiving the position detection signal, and controls the switch circuit.</p> |
