The magnetic flux sensing element 5 is mounted on the opposing surface on the permanent magnet 2, and the magnetic flux 3a generated in the driving permanent magnet 1a is applied to the magnetic flux 4a generated in the phase control permanent magnet 2. By influencing the magnetic flux lines by the combination of the magnetic flux lines of the driving permanent magnet 1a and the phase control permanent magnet 2, the magnetic flux lines are distorted as shown in FIG. 2, thereby reducing the accuracy of the phase control signal. When the phase control permanent magnets 2 are coupled to each other, the assembly direction is distorted to increase the distortion of the phase control magnetic flux lines.
