Permanent magnet motors have the advantages of high output torque, efficiency, and low noise, but cogging effect is obvious. The 24-slot 4-pole surface-mounted permanent synchronous motor taken as an example to reduce torque motors. Firstly, generation mechanism analysed based on energy method, pole arc coefficient, air gap length, magnetic eccentricity, thickness, slot opening width are determ...

In this paper, the torque production of fractional slot concentrated winding (FSCW) permanent magnet synchronous machines (PMSM) are analyzed from the perspective of the air-gap field harmonics modulation accounting for slotting effect. It is found that the average torque of FSCW PMSM is produced by both the principle of conventional PMSM and the magnetic gearing effect. A finite element analys...

A surface-mounted permanent magnet synchronous motor (SPMSM) is an electric with a simple magnetic circuit design, fast responsiveness, linear torque–current characteristics, speed–voltage and constant operating speed. SPMSMs use only torque; however, interior PMSMs (IPMSMs) have high power densities because they can reluctance torque. In addition, when flux-weakening control used, the range wi...

In this paper, a generalized formula is proposed for the selection of number of slots required for n-phase alternative current (AC) machine design and the criterion for selecting the starting points of each phases. The analytical model is verified using a four-pole machine with a 36-slot stator. Each coil of the stator winding of this machine is brought out to a patch board that enables the sta...
