Physical Configuration Revolution: White Paper on Axial Flux Motor Technology
Starting from Maxwell's equations, the disc structure of the axial flux motor realizes the topological optimization of the magnetic field path. Its air-gap magnetic field is completely parallel to the rotor distribution. Compared with the vertical magnetic field loop that must be constructed for radial flux motors, the effective magnetic circuit length is shortened by 37% (measured data). This electromagnetic innovation brings three inherent advantages: ① The power density exceeds 5.8kW/kg (the industry average is 3.2kW/kg); ② The copper loss is reduced to 78% of the traditional solution; ③ The axial force fluctuation is controlled within ±2.3N·m. The PDS450KCA assembly of the disk hub is precisely based on this, integrating the motor, reducer and differential in a 755mm axial space. Its unique "sandwich" winding process enables the slot fullness rate to reach 92%, far exceeding the industry level of 75%. It is worth noting that this technology has reduced its reliance on rare earth materials by 40%, which is of strategic significance for building a sustainable supply chain.
