Abstract: A two-phase or three-phase claw-pole type rotary machine comprises two or three coaxially arranged single phase rotary machine elements. Each of the rotary machine elements has a magnet rotor, a claw-pole type stator, and an annular stator winding. Claw poles of the stator are divided into a plurality of blocks and are circumferentially separated from one another. A distance between adjacent claw poles of the same polarity in each block is (β0−Δβ), substantially, where β0 is a reference pitch when the claw poles of the same polarity are arranged equidistantly apart from one another in a range of 360°, Δβ is π/2q, or π/3q and q is a number of claw poles of the same polarity in each block. The first and second rotary machine elements are circumferentially shifted from each other by 90° or 120°.

Abstract: Transverse flux electric motors are made using a unique process where individual components are premade and then assembled together. A stator portion is made by nesting a coil between two stator core portions. The stator core portions are made from laminations or sintered powder materials. A separate rotor portion is provided with a core and two permanent magnets that interact with projections on the stator core portions. In one example, the stator includes support members that support additional magnetic core portions to magnify the magnet flux density in the air gap between the stator and the rotor.

Abstract: Rotary permanent magnet motors have salient stator poles with nonuniform pole thickness in the radial direction for compensating effects of cogging torque. Pole base portions terminate at pole shoes at the radial air gap. The pole shoes extend in the circumferential direction from the bulkier base portions. Variation of the thickness of the pole shoe changes the concentration of the effective flux at the point of coupling between the stator poles and the permanent magnet pole shoes. As there is no change in the active interfacing area of the pole shoes a uniform air gap is maintained. The torque signature for each stator pole/rotor permanent magnet interface can be selectively changed to smooth motor operation by configuring the stator pole shoe thickness to vary along its circumferential extent as appropriate. Pole shoes may have tapered leading or trailing edges with respect to a pole base to change the effective flux density in the air gap at a specific pitch of rotation. Additionally, the pole shoe may be shifted off center with respect to the pole base.

Abstract: A hybrid synchronous electric machine driven by the transverse magnetic flux has a rotor and a stator, the rotor armature has a massive cogged iron rings (12) in close vicinity of active parts of the motor, and cogged iron rings (14, 15) as component parts of the rotor are provided with cross-cut insulating gaps. Eddy current losses are low because eddy currents in cogged iron rings are impeded by cross-cut insulating gaps therein. Eddy currents in all passive parts of the motor (rotor armature (11), stator armature (1), ball bearing (9) and the like) are negligible since the current induced in the copper ring (12) neutralizes all the dissipated magnetic flux outside the active area of the motor. A hybrid synchronous electric machine which has low eddy current losses and high energy efficiency can be realized.

Abstract: In electric machines, core losses limit, at high fundamental frequency, the permissible full-load power. The aim of the invention is to develop a design which enables a high power density at high magnetic reversal frequencies and which is easy to produce. To this end, the primary part comprises coils which, for the majority of their length, run in the direction of movement and which are surrounded in this area on three sides by soft magnetic material. In the direction of movement, at least two coils are arranged one behind the other. Coils of different phase are arranged perpendicular to the direction of movement inside different running tracks. In the secondary part, at least two oppositely magnetized hard magnets with three collector segments, which are flatly adjacent in a manner that is perpendicular to the direction of movement, form magnet poles having a high flux concentration. The primary and secondary parts can be shifted with regard to one another in a manner that is perpendicular to the direction of movement by means of a mechanism. The machine is characterized by having an easily producible modular design which has low core losses also at high frequencies. A high power density and, at the same time, a large low-loss field control area is realized in compact dimensions.

Abstract: A method of increasing the power output of existing permanent magnet motors along with apparatus is disclosed. Increased power output is achieved by more completely utilizing the magnetic field of motor permanent magnets during running. The apparatus is external to the motor and therefore eliminates the need for modifications to the motor itself. The method involves providing a source of power to a permanent magnet motor which is capable of demagnetizing the motor permanent magnets at stall, and reducing the power at start up to a level sufficient to prevent demagnetization. Full power to the motor is provided when the motor speed reaches a level sufficient to prevent demagnetization of the permanent magnets.

Abstract: A rotor disc (14), for use in an electrical machine (10), has at least one circumferential rotor rim (16) mounted thereon. The rotor rim (16) comprises at least one row of alternate magnets (20) and laminated pole pieces (18).
