| 20090267437 | SERVO MOTOR AND ROTOR THEREOF - A servo motor, comprising a stator and a rotor disposed within the stator. The rotor has a core and magnets, covering the periphery of the core, forming a plurality of axially extending rotor poles. The rotor poles comprise a plurality of the magnets arranged axially, and the centers of adjacent magnets of a rotor pole are staggered by a mechanical angle in the circumferential direction of the rotor. | 10-29-2009 |
| 20090322174 | PERMANENT-MAGNET SYNCHRONOUS MACHINE WITH REDUCED TORQUE RIPPLE - In a three-phase permanent-magnet synchronous machine, a pole gap and a skew of permanent magnets on the rotor are designed such that oscillating torques which are caused by the fifth and seventh harmonics of the stator field and of the rotor field are mutually reduced. In particular, the skew can be chosen as a function of the pole gap, such that the majority of the respective oscillating torques is neutralized. This results in minimal torque ripple. | 12-31-2009 |
| 20100219711 | Auxiliary Assembly of an Internal Combustion Engine - In the drive train of a combustion engine an auxiliary arrangement is arranged which is to be coupled with an axial flow machine comprising a stator and a rotor, in order to perform an actuating movement. The stator has a coil arrangement, and the rotor has an essentially cup-shaped support for permanent magnet elements. The coil arrangement of the stator has at least one cylindrical winding and is at least partially enclosed by two essentially pot-shaped magnetic flux yokes. Each of the pot-shaped magnetic flux yokes has side areas with magnetic flux poles whose outsides are oriented towards the permanent magnet elements of the rotor. The magnetic flux poles of the stator are arranged spaced apart from the permanent magnet elements of the rotor. The magnetic orientation of neighbouring permanent magnet elements towards the air gap alternates. | 09-02-2010 |
| 20100277026 | ROTARY ELECTRIC MACHINE - A rotary electric machine comprising a rotor ( | 11-04-2010 |
| 20120280588 | MAGNETIC ROTATIONAL DEVICE - A rotating device having a stator and rotor, in which paired arcs of staggered magnets are affixed to the rotor surface, such that the staggered magnets are off-set the center-line of the rotor. Stator magnets, located on the stator, are also affixed in an off-set manner. During rotation, the repulsive interaction between stator and rotor magnets is off-set the centreline of the rotor, resulting in a tangential force on the rotor, which imparts angular momentum on the rotor, thereby inducing rotation. | 11-08-2012 |
| 20150015107 | Vibration Prevention in Synchronous Machines - Spatially mutually close pole components are offset with respect to one another such that their influences on a given harmonic of the vibrations occurring during operation cancel one another as much as possible. The present invention therefore suggests concepts and makes dimensioning proposals by means of which certain harmonic orders of the operating noise can be reduced. | 01-15-2015 |
