Abstract: A rotor of a rotary electric machine includes a first magnet and a fourth magnet whose magnetic fields are oriented in radial directions of a stator, and a second magnet and a third magnet whose magnetic fields are oriented in circumferential directions of the stator. Teeth portions of the stator each include a base portion that protrudes in a radially inward direction of a yoke portion, a flange portion that is wider than the base portion, and an expanding portion interposed between the base portion and the flange portion. An angle of intersection between the base portion and the expanding portion is 108° to 130°. A distance (thickness) from an inner circumferential side end part to an outer circumferential side end part of the flange portion is 0.2 mm to 2.0 mm.

Abstract: A first magnet, a second magnet, a fourth magnet, and a third magnet are retained on a rotor of a rotary electric machine in this order alongside one another in a circumferential direction. Magnetic fields of the first magnet and the fourth magnet are oriented in radial directions of a stator. Magnetic fields of the second magnet and the third magnet are oriented in circumferential directions of the stator. When the rotor is viewed in plan from above or below, a ratio of a total surface area of the first magnet and the fourth magnet to a total surface area of the second magnet and the third magnet is S14:S23=1:0.2 to 1:1.

Abstract: A rotor of a rotary electric machine includes a first magnet and a fourth magnet whose magnetic fields are oriented in radial directions of a stator, and a second magnet and a third magnet whose magnetic fields are oriented in circumferential directions of the stator. In the stator, slots are formed between adjacent ones of teeth portions. An electromagnetic coil is provided in the slots. A distal end on an inner circumferential side of the electromagnetic coil is offset from an inner circumferential side end part of a base portion, which is a part of the teeth portion, toward a yoke portion.

Abstract: Provided is an omni-wheel including an annular core member for rotatively supporting a plurality of free roller that is light, economical and strong. The omni-wheel comprises an annular core member having at least one junction defined by mutually circumferentially opposing ends thereof, a plurality of sleeve members defining an inner bore and passed onto the core member and a free roller rotatably supported on an outer surface of each sleeve member in a coaxial relationship, wherein the mutually opposing ends of the annular core member at each junction are fitted into either end of the inner bore of the corresponding sleeve member.
