PROBLEM TO BE SOLVED: To obtain a motor with frequency power generator which can step up an output voltage of a frequency power generation signal even without addition of a thrust anisotropic permanent magnet. SOLUTION: A rotor is provided with a permanent magnet 4 to form a magnetic field provided opposed to a stator at the internal circumference of a cylindrical portion 3a of a cup-type yoke 3. The stator is provided with a printed circuit board 5 mounting a controller of this motor. The printed circuit board 5 is also provided with a frequency power generation coil pattern 7 opposing to a gap 6 at the end surface of the field permanent magnet 4. A frequency power generator 8 is composed of the field permanent magnet 4 and the frequency power generation coil pattern 7. A frequency power generation coil pattern 7' is provided also to the surface in the opposite side of the surface of the printed circuit board 5 where the frequency power generation coil pattern 7 is provided. These frequency power generation coil patterns 7, 7' are connected to provide a larger power generation output. |
