Abstract: A driving apparatus for a washing machine includes a single-phase outer rotor brushless motor and a driving wheel. The motor drives the driving wheel and includes a stator and a rotor. The stator includes a stator core and windings wound around the stator core. The rotor includes a rotor yoke, and a permanent magnet. An inner surface of the permanent magnet and an outer surface of a tooth tip are opposed to each other and define an uneven gap there between for allowing the rotor to rotate relative to the stator. A radial width of the gap associated with each magnetic pole progressively increases from a center portion toward circumferential ends of the magnetic pole, and a radial width of the gap associated with each magnetic pole is symmetrical with respect to a center axis of the magnetic pole along the circumferential direction.

Abstract: An electromagnetic drive mechanism (10) comprises a rotor (50) configured to rotate within a stator (30). The rotor (50) and stator (30) have multiple poles (56, 36), wherein each pole comprises a radial inner portion (564, 362) and a radial outer portion (562, 364). The radial inner portions (564, 362) and radial outer portions (562, 364) of the rotor (50) and stator (30) have different heights, forming a step (566, 366) between the radial inner and outer portions of the rotor (50) and stator (30). This configuration allows for overlapping radial surfaces in addition to overlapping axial surfaces during operation of the drive mechanism (10), thereby increasing the total overlap area and thus the reluctance torque, and potentially improving response speed while allowing for a more compact device (10).

Abstract: A permanent magnet embedded motor includes a rotor and permanent magnets. The outer circumferential surface of the rotor is formed by divided outer circumferential surfaces divided at equal angle intervals in a circumferential direction corresponding to permanent magnets. The divided outer circumferential surface is formed by a first curved surface, a radial direction distance of which from a rotor axis is maximized in a circumferential direction center of divided outer circumferential surface and second curved surfaces formed from the circumferential direction both ends to the circumferential direction center and crossing the first curved surface. The second curved surfaces are formed by—arcuate surfaces each having the rotor axis as a central axis. A distance between both ends of the first curved surface is smaller than the width of a permanent magnet in a direction orthogonal to a radial direction in the circumferential direction center.

Abstract: A generator (5) for a wind turbine (1) is disclosed. The generator (5) comprises a rotor (3) configured to rotate about a rotational axis, and at least one stator (4) arranged next to the rotor (3). Each stator (4) comprises at least two subunits (8), the subunits (8) being arranged side-by-side along a moving direction of the rotor (3). Each subunit (8) comprises at least one flux-generating module (9) facing the rotor (3) but spaced therefrom, thereby defining an air gap between the rotor (3) and each flux-generating module (9). The subunits (8) are movable relative to each other along a direction which is substantially transverse to the moving direction of the rotor (3). This allows a subunit (8) to move in a manner which adjusts the air gap without affecting the position and the air gap of a neighboring subunit (8). Thereby variations in the rotor (3) can be compensated and a uniform and constant air gap can be maintained. The invention further provides a wind turbine (1) comprising such a generator (5) and a method for performing service on a generator (5).
