To provide a structure of a stator of a multiple shaft multilayer motor which can reduce a loss due to an induced current, reduce the amount of a leakage magnetic flux from a main magnetic flux, and raise stator rigidity due to the force generated from the motor, together.
The multiple shaft multilayer motor M includes an inner rotor IR and an outer rotor OR disposed in a concentric disc shape via the stator S so that the stator S has positioning members for positioning a plurality of divided stator teeth 41 with coils 42 at an equal pitch interval on the circumference. The multiple shaft multilayer motor M further includes engaging parts 55a of the stator teeth 41 each composed of a laminated steel sheet and disposed at an equal interval on the circumference as the positioning members. Ring shaped members 55 obtained by finely forming the members between the engaging parts 55a and 55a are used. The ring shaped members 55 are set to the inner peripheral positions of the stator teeth 41. And, the stator tees 41 divided into the engaging parts 55a of the ring shaped members 55 are assembled.
