Abstract: A permanent magnet machine is provided with a rotor positioned at least partially within a stator. The rotor includes first and second ring segments oriented axially around a central axis. The rotor defines first and second configurations in the first and second ring segments, respectively. The first configuration is sufficiently different from the second configuration such that torque ripple may be minimized. A first layer of slots, defining a slot outer edge, may be formed in the rotor. In one embodiment, a stator-to-slot gap varies between the first and second ring segments. In another embodiment, a stator-rotor gap varies between the first and second ring segments. In another embodiment, a bridge thickness varies between the first and second ring segments. Thus the rotor exhibits axial asymmetry.

Abstract: A generator (5) for a wind turbine (1) and a wind turbine (1) are 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) comprising at least one flux-generating module (9) facing the rotor (3) but spaced therefrom. The flux-generating module(s) (9) is/are mounted on a stator support structure (7, 10). The stator support structure (7, 10) defines a pre-loaded spring force acting against magnetic forces occurring between the rotor (3) and the flux-generating module(s) (9) during operation of the generator (5). The preloaded spring force is adjustable, e.g. by means of a piston arrangement (17). Thereby it is possible to maintain a preloaded spring force which is capable of acting against the magnetic forces occurring between the rotor (3) and the flux-generating module(s) (9), even if operating conditions are changed. Furthermore, the preloaded spring force may be adjusted to compensate for inaccuracies originating from production tolerances of the stator support structure (7, 10). A uniform and constant air gap can thereby be maintained between the rotor (3) and the flux-generating module(s) (9).

Abstract: The synchronous motor includes a rotor including a rotor core constituted of segment poles disposed in a ring and a stator including a stator core disposed radially outward or inward of the rotor with a gap therebetween and a multiple-phase stator winding wound on the stator core. Each of the segment poles has a magnetic salient pole characteristic.

The lamination thickness as an axial length of the stator core is shorter than the lamination thickness as an axial length of the rotor core.

Abstract: An arrangement to set up and to ensure an air gap in an electrical machine, like a generator, is provided. The electrical machine includes a stator arrangement and a rotor arrangement. The rotor-arrangement rotates around a longitudinal axis. At least parts of the rotor arrangement interact with parts of the stator arrangement to generate electrical power. An air gap is defined by the distance between the parts of the rotor arrangement and the parts of the stator arrangement. The parts of the stator arrangement are opposite to the parts of the rotor arrangement along a certain length. The cross-section of the air gap changes along the certain length, so that the air gap is not uniform in view to the referred certain length.

Abstract: An improved structure for brushless motors comprises a stationary part and a rotary or movable part mounted relative to the stationary part. The rotary part includes a frame and a plurality of magnets disposed, one after another, along one surface of the frame and attached to the surface of the frame adjacent to the stationary part, wherein each of the magnets has a curved surface so as to define a series of gaps between the curved surfaces of the magnets and the surface of the frame of the rotary or movable part. With the present invention, the airgap between the stationary part and rotary or movable part would be more uniform, and the motor can be manufactured more easily. Also, when running the motor, cogging or no-current torque can be reduced or eliminated, so that the motor can be operated more smoothly.
