Abstract
The present invention provides a motor generator, and the motor generator comprises a permeability structure, a bearing, a hollow rotating shaft, a ringed clip and a rotatable guiding structure. The permeability structure comprises a primary permeability unit and a secondary permeability unit wherein the second permeability unit is stacked with the first permeability unit along an axial air-gap to form a symmetrical structure having a hollow shaft. The bearing is disposed inside the hollow shaft of the permeability structure. The hollow rotating shaft is passed through the hollow shaft of the permeability structure and disposed at another side of the bearing with respect to the permeability structure. The ringed clip is used for fixing the bearing and the hollow rotating shaft. The rotatable guiding structure is disposed inside the hollow rotating shaft for providing power source and transmitting signals.
