In a permanent magnet type concentrated winding motor, the number of magnetic poles is M, a stator Sr has teeth T around which coils are wound in a concentrated manner and which are circumferentially arranged at equal intervals, the number of teeth is N, M is equal to (18±4)n and N is equal to 18n (n is an integer and n ¥ 1), an armature winding AW has an m number of parallel circuits (m is an even number that is 2 or greater, and is a divisor of 2n), and a 1-phase circuit of the parallel circuit is configured to have a 6n/m number of coils connected in series with each other. A high-efficiency motor with a small size is obtained and a torque ripple also is small. Furthermore, since the second-spatial order electromagnetic excitation force is small, low vibration and low noise are obtained. In addition, the parallel circuits are formed and thus, it is possible to make a winding thin. Accordingly, a winding space factor is improved and manufacturability is improved.
