Permanent‑Magnet Synchronous Geared Motor Assembly

Technical Features of Permanent Magnet Motor

1、Higher slot fill factor: Compared with traditional round wire motors, the bare copper slot fill factor can be increased by 20%–30%, effectively reducing winding resistance and thereby lowering copper loss.

2、Better heat dissipation: The flat wire features a regular profile, fits tightly within the stator slot, delivers higher heat conduction efficiency and enhances the motor’s peak and continuous-duty performance.

3、 Shorter Winding End: Compared with round-wire motors, the winding end dimension is reduced, with the total end height shortened by 5–10 mm, lowering copper loss in the end winding.

4、 Compact Size & Light Weight: It eliminates separate motor three-phase cables and adopts integrated electronic control cooling water passage. The Motor Control Unit (MCU) and Range Extender Control Unit (RCU) are integrated, saving weight, space and cost.

5、Excellent Vehicle-level EMC Performance: Without three-phase high-voltage cables, the system reduces major sources of electromagnetic interference (EMI).

6、 Flexible Motor Structure Design: It adopts platform-based design with rated power options of 270, 315, 330, 400, 430 and 700 kW, enabling short product development cycles.

7、High Efficiency: The motor’s peak efficiency ≥ 97%, and the operating range with efficiency exceeding 90% accounts for more than 83%, effectively cutting energy consumption.

8、High Reliability: The motor adopts IP68 rating, the industry’s highest level of dust and water protection. It can adapt to harsh working conditions.Within the full speed range (peak operating conditions limited to permitted duration), the motor temperature remains below 140°C.
