<p>The present invention provides a wheel structure of an inner stator portion with an inbuilt driving control circuit, which has the advantages of shortest conductor length, lowest wire resistance, and immune to diturbance. The inner stator portion is divided into a stator inner ring, stator teeth, and grooves for the wires. The grooves are sleeved into the stator inner ring after stator coils are installed therein. Wire heads/tails of the stator coils are respectively soldered to a stator winding connector. The stator inner ring has a maximal hollow space. Two end cover plates cover the two end faces of the inner ring portion. The covered inner ring portion, having the hollow space, can receive a drive control circuit. Central parts of the end cover plates have a concentric hole so that a supporting shaft can be tightly joined therein. <IMAGE></p> |
