Abstract
This paper presents a novel stator design to reduce harmonics in the air-gap flux density of electrical machines with concentrated windings and further to improve the electromagnetic performance. The stator contains magnetic flux barriers in its teeth region to increase the amplitude of the fifth harmonic and is applied for a 12-teeth/10-poles PM machine with a three phase single layer concentrated winding. Compared with the conventional design and a 12-teeth/14-poles PM machine with and without flux barriers the new machine design shows significant improvements concerning the performance, power density and efficiency.
