PURPOSE:To improve the efficiency of a motor and to facilitate a winding work by burying the lower coil side of one coil in the slot of an armature core, and disposing the upper coil side in a gap between the inner periphery of the core and the outer periphery of a field permanent magnet. CONSTITUTION:Lower coil sides 2, 5 are buried in slots 9, and upper coil sides 3, 6 are disposed in gaps. Accordingly, the slot sectional area may have an area to introduce the sides 2, 5 to be approx. 1/2 of that of the conventional example in which 2-layered coil sides (e.g., coil sides 5, 3) are buried. Therefore, the depth of the slit 9 may be substantially 1/2 of that of the conventional example. Then, a rotor has a mechanical gap from the coil layers of the sides 3, 6 disposed in the gap, and 6 field permanent magnets 8 are disposed at an equal interval.
