The slots have coil sides of coils of a winding system in such a manner that two coil sides of different coils are situated in each slot. The rotor has a cylindrical support structure which is provided with permanent magnets defined by an inner radius which corresponds to a radius of the support structure, and by an outer radius which is smaller than their inner radius. The permanent magnets are formed with ten magnet poles when viewed in a circumferential direction. | 06-03-2010 |
| 20100264770 | PERMANENT-MAGNET SYNCHRONOUS MACHINE WITH SUPPRESSION MEANS FOR IMPROVING THE TORQUE RIPPLE - A permanent-magnet synchronous machine for suppressing harmonics includes a stator and a rotor with permanent magnets. Each permanent magnet represents a magnetic pole and is, when viewed in the circumferential direction of the rotor, shaped as a parallelogram or an arrow. The pole coverage is less than one. The permanent magnets are staggered at a staggering angle, wherein the permanent magnets of one pole are arranged in the axial direction with an increasing offset of a circumferential angle in relation to a first permanent magnet of this pole. Each permanent magnet is skewed at a skew angle defined by a circumferential angle of a projection of a tip portion of the parallelogram or arrow. The optimal skew and staggering angles are calculated from the design parameters for the stator and the number of pole pairs and the number of poles in the axial direction of the rotor. | 10-21-2010 |
