摘要： A rotary electric device includes a stator, and a rotor including a rotor core having magnetic poles and permanent magnets at the magnetic poles. Each of two embedding holes in each magnetic pole includes a loading region in which the permanent magnet is loaded, an inner periphery-side gap, and an outer periphery-side gap. Defining D as the minimum distance from the outer periphery-side gap to an outer peripheral surface of the rotor core, Was the width of a teeth of the stator, H0 as the sum of the magnetomotive forces generated in the portion corresponding to a magnetic pole angle Θ in one magnetic pole, and H1 as the magnetomotive force generated in one tooth, the rotor core is formed such that D≥W×(H0/H1).

摘要： According to one embodiment, a stator includes a stator core and a stator coil. The stator core includes an annular yoke, and a plurality of teeth each extending from an inner periphery of the yoke in a radial direction and arranged in a circumferential direction of the yoke at intervals, in which a gap between a pair of teeth adjacent to each other in the circumferential direction forms a slot extending in the radial direction. With respect to the pair of teeth and the slot, only one of the teeth includes a convex holder-shaped part which projects in the slot toward the other tooth and extends in an axial direction. The stator coil includes a plurality of linear conductors aligned in the radial direction in the slot and held in the slot by the holder-shaped part.
