More than three times the target for 2035! Starting from 21kW/kg, it initiates an industrial revolution of disruption and reconstruction in the electric drive of new energy vehicles

  The innovation capabilities of domestic new energy vehicle component enterprises in China are redefining the evolution path of electric drive technology.

  At the 2025 Shanghai Auto Show, Panhu Power showcased two new axial flux motors featuring ultra-high speed and ultra-high power density. Among them, 

the Panhu ICD306K motor has a peak power of 306kW, a maximum speed of 18,000 RPM, an effective power density greater than 21kW/kg, and an effective

torque density of 32.5N·m/kg.

  According to the "Technical Roadmap 2.0 for Energy-saving and New Energy Vehicles" of our country: By 2035, "the power density of high-performance 

passenger vehicle motors will reach 7.0kW/kg, and the peak torque density of hub motors will reach 30N·m/kg".

  According to this data, the mass power density and torque density of the hub ICD306K have both achieved the planned targets for 2035 ahead of schedule.

With an effective power density of 21kW/kg, it has exceeded the planned target by three times and can be said to "represent the performance limit of 

current new energy vehicle drive motors".

  "Power density", as a key indicator for measuring motor performance, reflects the motor's power output capacity per unit volume or mass. In short, the 

higher the power density, the better the motor's efficiency and performance.

  The demand for motor power density in new energy passenger vehicles is "endless".

  In recent years, the core reason why mainstream domestic and foreign automakers such as Mercedes-Benz, Dongfeng, GAC and Chery have frequently 

paid attention to axial flux motor technology is that under the same power, the volume and weight of axial flux motors can be reduced by about 50% 

compared with traditional radial flux motors, and the power density of the motor can be increased by several times.

  On the other hand, under the condition of limited volume and weight, increasing the rotational speed to enhance the output power is also the mainstream 

approach to currently boosting the power density of motors

  However, from the perspective of the motor's topological structure, the rotor of a radial flux motor usually rotates inside the stator, with the outer diameter 

of the rotor being approximately 60% to 70% of the stator's outer diameter. It is relatively simple to achieve and maintain a high speed of over 15,000 RPM.

  The outer diameters of the stator and rotor in an axial flux motor remain equal, so the effective air gap area of the entire motor's magnetic field is increased

and the effective force arm of the rotor during operation will also be larger. However, due to the larger outer diameter of the rotor, in various dimensions 

such as basic materials, mechanical stability, electromagnetic characteristics, and production assembly processes, To increase the peak rotational speed to 

over 15,000 RPM, a large number of technological innovations and problem-solving efforts must be accomplished.

  As the world's first enterprise to achieve large-scale production and application of axial flux motors, Panhu has established a complete forward 

development process, covering all aspects from obtaining customer requirements, optimizing the architecture design, developing and manufacturing 

sub-components, to the final integration verification. To support the efficient operation of this process, Panhu has also established a comprehensive 

forward development capability system, covering all aspects of technological research and development from basic material research to technological 

innovation of motor stators and rotors, gear shafts, as well as production manufacturing and assembly processes.

  The release of the ICD306K motor by Panhu has raised the peak speed of axial flux motors to a brand-new level of 18,000 RPM, marking a "new peak" in 

the design and manufacturing process of axial flux motors by Panhu. It also provides a new paradigm for the technological revolution and value upgrade of 

the new energy vehicle industry. It is worth noting that using axial flux motors with higher power density as the power core not only effectively enhances 

vehicle performance but also often brings a significant differentiation advantage in the "more precious" axial dimensions of vehicle space layout. Hub power, 

thumbs up 7

  Take the distributed drive system that all major new energy vehicle manufacturers are actively laying out as an example. When many manufacturers are 

planning the power system, they all expect that the axial size of the dual-motor distributed drive assembly coaxially arranged can be controlled within 

600mm. However, in reality, The mainstream scheme of radial flux motor layout that can meet the power requirements of vehicles generally has an axial 

dimension of over 600mm, thus creating a strong pain point.

  The distributed drive assembly featuring two hub ICD306K axial flux motors has its axial dimensions controlled within 500mm, effectively keeping the total 

weight of the entire system within 95 kilograms. The peak power reaches 612kW, and the power density of the drive assembly exceeds 6.4kW/kg, which is atthe leading level in the industry.

  The automotive industry revolution centered on electrification is booming. Pan Gu, with technological innovation as its spear, looks forward to joining 

hands with all partners for in-depth cooperation to redefine the value and future of new energy vehicle drive systems.
