摘要： An axial flux motor includes a housing; a drive shaft disposed within the housing; at least one rotor; and at least one stator. The at least one rotor includes a diametrically-magnetized single pole pair magnetic ring having a rotor aperture defined through the center of the magnetic ring, where the drive shaft extends through the rotor aperture and where the at least one rotor is fixed to the drive shaft. The at least one stator includes a number of conductive windings and a stator aperture, where the drive shaft extends through the stator aperture and where the drive shaft is rotatable within the aperture. The at least one stator is configured to generate an axial magnetic field that causes the at least one rotor to rotate, thereby rotating the drive shaft.

摘要： A rotor for an electric motor includes an axis, a rotor carrier a plurality of rotor segments, a first end plate, a second end plate, and a spring element. The rotor carrier has a tubular portion with a cylindrical surface and a radial wall extending radially outwardly from the cylindrical surface. The plurality of rotor segments circumscribe the cylindrical surface. The first end plate is disposed at a first axial end of the plurality of rotor segments adjacent to the radial wall. The second end plate is disposed at a second axial end of the plurality of rotor segments. The spring element presses the first end plate, the plurality of rotor segments, and the second end plate against the radial wall. The spring element includes a ring portion and a plurality of segments extending axially from the ring portion.

摘要： A stator (1) for an electric motor has a modular stator body (2) with at least two stator cores (10, 20) arranged axially in series. Each core (10, 20) is form from a plurality of stacked electrical laminations (11, 21). This forms winding poles (16, 26) with radially extending winding webs (17, 27). The stator cores (10, 20) each have a separate overmolding (U1, U2).

摘要： A high rotor pole switched reluctance machine (HRSRM) employs an axial and radial mirroring concept and is represented by a first Multiple Rotor Pole (MRP) formula and second Multiple Stator Pole (MSP) formula. A multiple rotor HRSRM comprises at least two rotors each having a plurality of rotor poles and at least two stators having a plurality of stator poles. The at least two rotors and the at least two stators are positioned about a central axis with the stator placed between the rotors. In other embodiments, the number of stators equals the number of rotors and effectively operate as a single stator and rotor. In yet another embodiment, the effective single stator and rotor type high rotor pole switched reluctance machine is realized as single stator and rotor positioned concentrically around a central axis.

摘要： Guide device for shuttles of a planar motor has a first end and a second end and defines a pose course of a shuttle between the first and second end. The first end, which defines an introductory pose of the shuttle, is arrangable on a first stator of the planar motor so that the introductory pose corresponds to an operationally controllable pose in relation to the first stator. The second end, which defines an exit pose of the shuttle, is arrangable on the first stator or a second stator of the planar motor so that the exit pose corresponds to an operationally controllable pose with respect to the first or second stator. The pose course includes at least one pose which is an operationally non-controllable pose with respect to stators of the planar motor. The guide device supports and stabilizes the shuttle in the at least one operationally non-controllable pose.

摘要： A generator system having a dynamo that contains an armature, a stator and a housing. The armature rotates about a first axis of rotation. The stator is concentrically positioned around the armature. Both the armature and the stator are free to rotate in opposite directions about the first axis of rotation. The housing of the dynamo is connected to a motor that can rotate the dynamo around a second axis of rotation. There is an angle of inclination between the first axis of rotation and the second axis of rotation. This angle of inclination is selectively altered during operation. By changing the angle of inclination between the two axes of rotation, a precession can be created that adds rotational energy to both the armature and the stator. This increases the output of the dynamo and creates a highly efficient electrical generator.
