The PDS320KW adopts an integrated structure combining an axial flux motor and planetary gear reduction. This design offers higher integration, a more compact footprint, and the flexibility to be configured with either dual-tire wheels or "super single" tires based on actual operational requirements. Furthermore, it enables combined drive and steer functionality on the rear wheels, significantly enhancing vehicle maneuverability. Thanks to the inherent structural advantages of the axial flux motor, this system achieves power transmission through only two gear stages, resulting in less kinetic energy loss and thereby effectively enhancing overall operational efficiency.
