2024 Taiwan Excellence Award

1. The driver adopts SiC module, high switching frequency, reduces the volume of the main capacitor, reduces the volume of the shell by 50%, and has low power loss, which can achieve ultra-high efficiency and higher power density.
2. The direct-drive motor has a high and weak magnetic ratio and optimized magnetic circuit to achieve lightweight motor, high-strength anti-vibration design, and optimal heat dissipation of water-cooling channels.
3. The motor design interface adopts direct drive, without a gearbox, which can reduce the NVH of the vehicle and flexibly utilize the chassis space of the vehicle
4. Meet the power demand of 12-meter electric bus, the highest climbing ability is 20%, and the top speed is 96kph
5. The domestic first ultra-high power system efficiency reaches 98% (motor 78%; drive 99%)
6. With a strong system structure, high output torque, high torque density increased by 25%
