ABSTRACT:
A motor includes an armature and a field magnet which surrounds the armature. The armature includes a plurality of teeth being arranged at equal pitch, and the field magnet includes a plurality of magnetic poles being arranged at equal pitch. When the number of the magnetic poles of the field magnets is "2P" and the number of phases of divided armature windings is "Q", the number T of the teeth is determined in accordance with an equation T=(P.+-.N) Q (O<N<N<P-2P/Q). In addition, "phase" and "winding direction" of the divided armature windings to be wound on the respective teeth are determined through comparison of an actual angle in electrical degrees of respective one of teeth and an ideal angle in electrical degrees corresponding thereto.
