摘要： A rotor for an electric motor (10) includes a magnetic assembly (12) formed into a ring-shaped plate form, a rotor disc (11) for holding an inner periphery of the magnet assembly, and an outer peripheral ring (13) for holding an outer periphery of the magnet assembly. The magnet assembly is composed of first and second main magnets (12A-1, 12A-2) having magnetizations directions that are oriented perpendicularly and having orientations that are opposite one another, and first and second submagnets (12B-1, 12B-2) having magnetization directions that are oriented perpendicularly in a circumferential direction and having orientations that are opposite one another. At least one group of magnets selected from the main magnets and the submagnets has a wedge-shaped planar part. The planar parts of the first and second main magnets and first and second submagnets form the same plane of rotation. The magnets are arranged so that the magnetization directions of adjacent magnets are perpendicular to one another.

摘要： A brake structure for a wheel rotating device includes a motor provided in a wheel and is driven for rotating the wheel, and a braking mechanism for actuating brake to brake the wheel. The motor includes: a motor housing; a stator positioned in and fixed to the motor housing; and a rotor positioned in the motor housing and facing to the stator. The braking mechanism includes: a brake rotor to rotate with the wheel; frictional members to be in contact with the brake rotor for generation of braking force; a pressing force generating unit for generating pressing force of the frictional members so that the frictional members are urged to and pressed against the brake rotor by supplying brake fluid through a brake fluid passage to transmit fluid pressure; and a housing for the pressing force generating unit. The brake fluid passage is formed inside a wall of the motor housing, and is connected to a brake fluid supply port provided in the housing for the pressing force generating unit.
