Abstract: A rotating electric machine according to an embodiment of the present invention includes a rotor; a stator; an insulator; and a coil. The rotor rotates about a first axis. The stator includes teeth projecting toward the rotor. The insulator is attached to each of the teeth. The coil is wound around the insulator. The insulator includes a pair of side surface portions that are mounted on the teeth to generate a biasing force against the teeth in a twisting direction with respect to a direction of the first axis.

Abstract: The rotor includes the rotor core unit and a single cylindrical rotor cover. The rotor core unit has the rotor core fixed to a rotation axis so as to be able to rotate integrally therewith and a plurality of permanent magnets mounted on the rotor core along a circumferential direction thereof. The single cylindrical rotor cover has the upper surface portion and the bottom portion so as to cover an outer circumference of the rotor core. The upper surface portion is in contact with an outer circumferential edge portion of on one end surface in an axial direction of the permanent magnets. The bottom portion is in contact with at least one of the permanent magnets and the rotor core so that the rotor core unit is held in the axial direction by the upper surface portion and the bottom portion.
