TMC2025: Hub axial magneto-current drive drives a technological revolution in the power systems of new energy vehicles

The 17th International Conference on Automotive Powertrain Technology (TMC2025) was held at Nantong International Convention and Exhibition Center from June 12th to 13th. Panhu Power showcased its core axial flux motors and electric drive solutions at this grand event and delivered a special presentation on "Engineering Application Practice of Axial Flux Motors in Heavy Truck Electric Drive Axles", demonstrating the company's innovative strength and cutting-edge achievements in the power systems of new energy vehicles and commercial vehicles.

Since 2009, TMC has been deeply engaged in the industry for sixteen years and has become the largest international conference and exchange platform for automotive power system technology, a benchmark summit in the field of automotive transmission and new energy technology in China, and also an important platform for showcasing and exchanging new technologies, new products and new processes in the industry.

As a leading enterprise in the global axial flux motor field, Panhu Power's innovative solutions such as integrated heavy-duty truck electric drive axles showcased at this year's TMC conference have been highly sought after. Dr. Tian Chengwei, the vice president of the Pan Hub Engineering Institute, said in an exclusive interview at the conference that "the configuration of the axial flux drive scheme is completely different from that of the ordinary electric drive scheme." Especially in the automotive power system where the layout space is tight, the "small, light, thin, large high-efficiency zone, and easy to arrange" axial flux motor has brought about a disruptive value upgrade and innovation. It has found new solutions for the entire industry.

Heavy-duty trucks are transportation tools for strong scenarios. In every unique transportation scenario, the "smaller, lighter and more efficient" hub axial flux motor can bring users a disruptive value upgrade and improvement.

At the "Deepening Topics of Electric Drive Axles" forum, Dr. Tian gave a special presentation on "Engineering Application Practice of Axial Flux Motors in Heavy Truck Electric Drive Axles". He believes that "heavy trucks are transportation tools with strong scenarios", and axial flux drive can create disruptive value upgrades and improvements for users in various scenarios.

For instance, in the field of integrated heavy-duty truck electric drive axles, disc hub products have been delivered in batches for market application. With nearly 3 million kilometers of actual working conditions verified, they operate reliably and stably, and have outstanding energy-saving effects. According to the statistics of a certain coal transportation route in Shanxi Province, the average monthly energy consumption of the new energy heavy-duty truck fleet equipped with hub electric drive axles is only 1.32 kilowatt-hours per kilometer, and the minimum energy consumption per vehicle reaches 1.08 kilowatt-hours per kilometer, which is far lower than the energy consumption level of similar products in the market.

In the central drive scheme design, the PDS450KCA drive assembly launched by Pan Hub Design weighs only 355kg and has an axial dimension of 755mm. Compared with the scheme using radial flux motors, its self-weight is reduced by more than 100kg and the axial dimension is shortened by approximately 340mm. It is extremely compact, with the motor's high-efficiency zone reaching 92.5%, providing stronger driving force and better adaptability to working conditions. Lower usage cost; Meanwhile, relying on the typical features of axial flux motors such as "small size, light weight and high efficiency", the hub can also provide more suitable products for more scenarios and working conditions, providing innovation-driven impetus for the technological revolution of automotive power systems!
