Abstract: A stator includes: a stator core having a yoke and teeth projecting from the yoke; coils attached to the stator core so as to surround the teeth; and coil fixing members, each of which is arranged at at least one of opposite ends of the stator core in a gap formed between an end face of the tooth and an inner side of the coil facing the end face. The coil fixing member includes a locking part that projects on the opposite side from the end face of the tooth to lock the coil and a projection that projects on the opposite side from the locking part, and the projection is inserted into an insert hole formed on the stator core.

Abstract: A stator includes multiple coils. The coils include multiple outer coils arranged on the base side of teeth and multiple inner coils arranged on the tip side of the teeth. The outer coils and the inner coils are alternately arranged along the circumferential direction of a stator core. Each coil winding of the outer coils is formed in a non-fixed state, and each coil winding of inner coils is formed in a fixed state.

Abstract: A stator which prevents deformation of component elements of the stator and which effectively removes heat generated by coils at the time of operation. The stator of a motor comprises a stator core having a cylindrical back yoke and teeth projecting out from the back yoke to the inside in the diametrical direction, coils wound around the teeth, an outer cylinder surrounding the back yoke, and heat conducting parts abutting against both an inner circumferential surface of the outer cylinder and coil ends of the coils.

Abstract: In the rotor of the present invention, each magnet has an inward part adjoining the rotor core and an outward part positioned outward of the inward part in a radial direction of the rotor core. The outward has a facing surface which faces a stator and a pair of side surfaces which extend from two end parts of the facing surface in a circumferential direction toward the inward part. The inward part has a pair of overhanging parts which overhangs outward in the circumferential direction with respect to the pair of side surfaces of the outward part. Each locking projection of the rotor core passes between overhanging parts of two adjoining magnets and projects outward in the radial direction to engage with the overhanging parts.
