<p>An auxiliary magnetic motor (AMM) comprises a fixed ring formed of a multi-layer flat silicon steel plate with a plurality of coils formed thereon, the fixed ring being fixedly supported within a motor case. The AMM also comprises at appropriate positions on the fixed ring at least three Hall effect IC sensors for sensing and producing a switching sequence signal for the fixed ring. The motor case center connects to one end of the axle of the bicycle wheel to be driven. The AMM further comprises a flat rotating plate having an outer ring portion having formed thereon a plurality of magnetic elements. Matching speed sensor elements are appropriately located respectively on the motor case and the cover case to sense and feedback the rotational speed of the wheel to a programmable control circuit, so as to actuate a motor control circuit which provides a three phase signal to the fixed ring to magnetically actuate the rotation of the rotating plate, thereby driving the wheel through various linkages and a gear mechanism.</p> |
