Due to the higher torque density, higher power factor, and higher efficiency the permanent magnet synchronous motor (PMSM) has became the first choice of many EV OEMs. However, Induction Motor (IM) is still a feasible choice in high speed powertrains due to the lower BOM cost, better NVH characteristics, and higher reliability. In SCnewton , we offer a comprehensive study of IM vs. PMSM allowing our customers to have the choice. Below, you can see apple to apple comparison of an 8 poles PMSM vs. a 6 poles IM.
Continuous power @ max speed: [55 kW@14500 rpm] PMSM vs. a [55 kW@17500 rpm] IM
Peak torque Z-PORT enabled: [350 N.m@4500 rpm] PMSM vs. a [425 N.m@ 2250 rpm] IM
Peak Power: [177 kW@9000 rpm] PMSM vs. a [120 kW@ 9000 rpm] IM
