| description | To mitigate the challenges of magnetic leakage and iron loss in the rotor of interior permanent magnet (IPM) motors, this article proposes a novel rotor structure that eliminates the bilateral bridge, relying solely on a central bridge to maintain rotor strength. This design reduces the overall bridge width of the rotor, thereby decreasing magnetic leakage and improving torque. The novel rotor features a distinctive design that combines high silicon steel sheets and low silicon steel sheets. High silicon steel sheets are used on the rotor's surface to minimize iron loss, while low silicon steel sheets are used internally to ensure rotor strength. This design takes advantage of the high silicon steel's low iron loss while mitigating its brittleness and saturation issues. The article describes the method for producing this combined rotor. Mechanical and electromagnetic property tests are conducted on both high and low silicon steel sheets, resulting in stress-strain curves, B-H curves, and iron loss characteristics. Finally, the rotor stress is calculated. The analysis indicates that this novel motor can reduce magnetic leakage, increase torque by 7.5 %, improve efficiency by 0.18 %, decrease rotor iron loss by 36.2 %, and lower rotor temperature by 3.9 % compared to the original motor. |
