Design and Analysis of High Power Density Permanent Magnet Synchronous Starter-Generator Considering No-load Back Electromotive Force Influence

The paper proposes a high power density dual three-phase permanent magnet synchronous starter-generator (DTPMSSG) considering no-load back electromotive force (EMF) influence. First, the 10-pole/12-slot DTPMSSG with two-layer concentrated winding is proposed, which has high power density and high reliability. Second, the influence of the no-load back EMF on the electromagnetic performance of the DTPMSSG is analyzed. Then the no-load back EMF of the DTPMSSG is optimized to guarantee both high power density and voltage stability control performance. Finally, the effectiveness of the proposed design is verified by the simulation.
