A stator assembly structure for an axial flux electric machine is designed. The back iron for each silicon steel disk stator is formed into a specific structure with tooth-like protrusions for allowing the same to be integrated with the disk-type stator seat, while the disk-type stator seat is made of a material suitable for casting or mold forming. A coil is mounted on the disk stator, and a stator assembly is achieved by integrating the stator, the coil and the stator seat. The stator and the disk-type stator seat of the stator assembly are manufactured by using a one-piece cast or one-piece mold forming method so as to enable the contact surfaces of the stator and the stator seat to engage with each other even more tightly, and consequently enable the heat generated from the coil to be transmitted rapidly from the disk stator to the disk-type stator seat.

A disassembled and assembled power module includes: a wheel shaft; a power module; a central shaft, arranged in the power module and passing through the wheel shaft; and an engaging unit, capable of fastening the central shaft to the wheel shaft. In an embodiment when the detachable power module is applied in an electric driven wheelchair, it enables the weight of the wheelchair to be reduced by simply detach and remove the detachable power from the wheelchair so that the electric driven wheelchair without the heavy power module can be carry and transport easily, and also the moving range of the electric driven wheelchair can be increased as its power module can be easily detached and replaced with another fully charged power module so that the range anxiety of the disabled person using the same or the assistant can be relieved.

A bidirectional continuous power transmission system, characterized by a projecting bolt moving within a guiding opening with a rear wall and a front wall. Upon a rotating movement, the projecting bolt exerts a force on the rear wall or the front wall, depending on the orientation of the rotating movement. The force has a component parallel to an axis of rotation, causing two halves of a driven wheel to be pressed together and against a transmission belt. By providing the rear wall and the front wall of the guiding opening with defined curvatures, well-defined forces are exerted at any speed in both orientations of the rotating movement, so that torque is continuously transmitted effectively in both directions.
