Title: Permanent magnet design to enable higher magnetic flux density

Abstract

A hybrid permanent magnet includes a first magnet (M1) having a first magnetic material and a second magnet (M2) having a second magnetic material different from the first magnetic material. The M2 magnet is deposited or assembled on a north pole surface and/or a south pole surface of the M1 magnet and the volume of the M2 magnet is less than or equal to the volume of the M1 magnet.

Direct control of air gap flux in permanent magnet machines

Patent Hsu, John S [Oak Ridge, TN]

A method and apparatus for field weakening in PM machines uses field weakening coils (35, 44, 45, 71, 72) to produce flux in one or more stators (34, 49, 63, 64), including a flux which counters flux normally produced in air gaps between the stator(s) (34, 49, 63, 64) and the rotor (20, 21, 41, 61) which carries the PM poles. Several modes of operation are introduced depending on the magnitude and polarity of current in the field weakening coils (35, 44, 45, 71, 72). The invention is particularly useful for, but not limited to, the electric vehicle drives andmore » PM generators. « less

Dual-rotor, radial-flux, toroidally-wound, permanent-magnet machine

Patent Qu, Ronghai; Lipo, Thomas A.

The present invention provides a novel dual-rotor, radial-flux, toroidally-wound, permanent-magnet machine. The present invention improves electrical machine torque density and efficiency. At least one concentric surface-mounted permanent magnet dual-rotor is located inside and outside of a torus-shaped stator with back-to-back windings, respectively. The machine substantially improves machine efficiency by reducing the end windings and boosts the torque density by at least doubling the air gap and optimizing the machine aspect ratio.

A permanent-magnet switched-flux (PMSF) device has a ferromagnetic outer stator mounted to a shaft about a central axis extending axially through the PMSF device. Pluralities of top and bottom stator poles are respectively mounted in first and second circles, radially outwardly in first and second transverse planes extending from first and second sections of the central axis adjacent to an inner surface of the ferromagnetic outer stator. A ferromagnetic inner rotor is coupled to the shaft and has i) a rotor core having a core axis co-axial with the central axis; and ii) first and second discs having respective outermore » « less

Permanent magnet machine and method with reluctance poles and non-identical PM poles for high density operation

Patent Hsu, John S.

A method and apparatus in which a stator (11) and a rotor (12) define a primary air gap (20) for receiving AC flux and at least one source (23, 40), and preferably two sources (23, 24, 40) of DC excitation are positioned for inducing DC flux at opposite ends of the rotor (12). Portions of PM material (17, 17a) are provided as boundaries separating PM rotor pole portions from each other and from reluctance poles. The PM poles (18) and the reluctance poles (19) can be formed with poles of one polarity having enlarged flux paths in relation to fluxmore » « less
