ABSTRACT:
A stator includes a frequency generating pattern, a driving coil composite pattern and lead lines. A rotor includes a frequency generating pattern, a driving coil composite and lead lines. A rotor includes a rotor magnet. A separation angle formed by the lead lines is an angle obtained by multiplying an integer and an separation angle formed by a pair of S-pole and magnetic poles of the rotor magnet adjacent to each other. Further, assuming that that an area between the lead lines and U-phase coils produce overlapping areas Su.sub.1 and Su.sub.2 in a top view, that the same area and a V-phase coil produce an overlapping area Sv.sub.1, and that the same area and a W-phase coil produce an overlapping area Sw.sub.1, the relationship Su.sub.1 +Su.sub.2 :Sv.sub.1 :Sw.sub.1 =1.0:1.0:1.0 exits. With this arrangement, the lead lines are least affected by the rotor magnet and the driving coil composite.
