a driving assembly for motor wheels including a plurality of permanent magnets arranged around the outer periphery of a securing element on an axle for forming a stator . when electric currents are passed through a plurality of winding coils in an inner wheel frame , an induction electromagetic field is generated to drive the inner wheel frame in the outer wheel frame to rotate . the inner wheel frame has a clutch ring for transmitting the power of the inner wheel frame to a driving gear of a reduction mechanism to drive the outer wheel frame . a clutch element is disposed between the clutch ring and the driving gear , the clutch element being capable of axial movement along the axis of said axle for controlling power transmission .
