At the Shanghai International Auto Show, the SHPG Power Technology Corporation booth was quite popular.
The company's innovative product axial flux motor has attracted executives from dozens of automotive OEM manufacturers, including Toyota, General Motors, Ford, Volkswagen, as well as executives from automotive component manufacturers such as ATP GROUP, Bosch, Borg Warner, AVTOR…to visit and communicated at the SHPG booth.
Compared with ordinary motors, the volume and weight of axial flux motors have decreased by about 50%, which is more conducive to the full utilization of chassis layout space;
On the other hand, the entire system integrates two motors, two MCUs, and two gearbox designs. The total weight of the system is only 100Kg, but the peak power can reach 300Kw, the output torque at the wheel edge is nearly 6000N · m, and the total success rate mass density reaches 3kW/Kg;
At the same time, this system assembly can freely choose multiple integrated layout schemes according to user needs, further saving chassis space, and more conducive to achieving modular and platform based product development and design;
The most crucial thing is that this system assembly achieves precise distribution and output of power to the connected wheels, perfectly implementing a distributed drive architecture, thereby comprehensively improving vehicle performance.
Thanks to the application of axial magnetic flux motors, the SHPG integrated heavy-duty truck electric drive axle adopts a three-speed gearbox, which greatly improves transmission efficiency. At almost every speed, the motor is in an efficient working range, and the dual mode shift mode can achieve differential shifting and power compensation of the front and rear axles. The entire vehicle does not experience power interruption during the shifting process;
Based on comprehensive calculations, under the same operating conditions, this electric drive bridge has a 30% improvement in power performance and a 15% reduction in energy consumption compared to traditional central drive electric drive bridges.
