- Abstract
- This study proposes a novel rotor shape for the spoke-type permanent magnet synchronous motor (PMSM) to improve its power performance by changing permeance and increasing magnetic flux density strength in the air gap. Applying a wedge-shaped barrier to the rotor results in a reluctance change in areas of the rotor that have saturated magnetic flux density, which changes the permeance in the air gap. In addition, magnetic flux can be transmitted to the air gap to increase the air gap magnetic flux density strength. In this study, a wedge-shaped barrier was used to maximize air gap magnetic flux density and torque, thus eliminating the magnetic flux density saturation area that negatively affects torque. This wedge-shape barrier also changes the inductances. The results confirmed that average torque improves as magnetic flux density saturation area is removed.
