Abstract: A motor having a stator that is configured by including a plurality of magnetic partial core members, which have a plurality of split ring cores forming a ring and coil support cores projecting outwardly from the respective center portions of the split ring cores. The partial core members are arranged and secured in a ring-shape with predetermined slits between them, and coils are mounted on each of the coil support cores, respectively. Accordingly, it is possible to obtain a thin and flat motor, in which coils are easy to wind, cogging diminishes, and assemble is easy to carry out, even if the outside diameter of the motor should be reduced.
