Difference between PMSM and SRM in EVs
Below listed the differences of these two motors –
| Aspects | PMSM | SRM |
|---|---|---|
| Construction | The rotor have permanent magnet and stator has winding. | Both rotor and stator has salient poles. |
| Magnetic field source | Rotor’s permanent magnet generate magnetic fields. | Stator winding generates magnetic fields. |
| Torque | Generate less torque | Generate high torque |
| Range of speed | It has limited speed range. | Wide speed range |
| Efficiency | High | Low |
| Noise | Low | High |
| Complexity | Construction is more complex. | Simple |
