    Abstract: A rotating machine comprises a stationary subassembly, a rotating subassembly, and a first circumferential track. The stationary subassembly includes a plurality of stator elements disposed proximate an inner circumference of a portion of the stationary subassembly, and a casing having a first portal. The rotating subassembly includes a plurality of rotor elements disposed proximate an outer circumference of a portion of the rotating subassembly. The rotating subassembly is aligned coaxially within the stationary subassembly and is rotatable relative to the stationary subassembly without the aid of support bearings. The first circumferential track is defined by a first rotor track portion on the rotating subassembly and a first stator track portion on the stationary subassembly, and is in communication with a first portal on the casing.

    Abstract: An apparatus for converting between mechanical and electrical energy, particularly suited for use as a compact high power alternator for automotive use and “remove and replace” retrofitting of existing vehicles. The apparatus comprises a rotor with permanent magnets, a stator with a winding, and a cooling system. Mechanisms to prevent the rotor magnets from clashing with the stator by minimizing rotor displacement, and absorbing unacceptable rotor displacement are disclosed. The cooling system directs coolant flow into thermal contact with at least one of the winding and magnets, and includes at least one passageway through the stator core. Various open and closed cooling systems are described. Cooling is facilitated by, for example, loosely wrapping the winding end turns, use of an asynchronous airflow source, and/or directing coolant through conduits extending through the stator into thermal contact with the windings.

    Abstract: A motor rotor includes an annular body and a magnetic body installed on an inner lateral surface of the annular body. The magnetic body has a first curved surface and a second curved surface opposing the first curved surface. The magnetic body props against the inner lateral surface of the annular body via the first curved surface. The first curved surface has a first curvature less than a second curvature of the second curved surface. Because the magnetic body of the motor rotor has an uneven thickness, and an air gap interval formed between the motor rotor and the stator also has an uneven width, forces applied to a region where the magnetic forces change directions are smooth. Therefore, the vibration of the whole motor is reduced, and the noises are suppressed effectively.

    Abstract: A motor, including at least a stator, including at least a stator core and a coil winding, and a rotor, including at least a rotor core and multiple permanent magnets. Multiple wire receiving grooves are disposed on the stator core. The permanent magnets are disposed on the rotor core. The ratio between the number of teeth of the wire receiving grooves and that of the permanent magnets is 3:2. Every two or three of the permanent magnets form a group of permanent magnets. A gap is disposed between adjacent groups of permanent magnets. The groups of permanent magnets are circumferentially distributed. Magnetic polarities of the permanent magnet are alternatively distributed in a N phase and a S phase. Difference in an electric angle between centers of polarities of adjacent permanent magnets in one group is between 150 degrees and 170 degrees.
