Experimental Results Regarding Cogging Torque Reduction for the Permanent Magnet Synchronous Motors PMSM

The goal of this paper is to present some of the methods for reducing the cogging torque present in permanent magnet synchronous motors PMSM. Some of the methods we analyzed: optimal selection of the stator`s pitch number and the poles number, the optimization of the geometry of the rotor’s pole and the skewing of the stator or skewing of the magnetic pole. These methods were applied in the design of the 10kW synchronous generator.
