The intercross coupled magnetic circuit structure with uniform magnetic resistance to adjust air clearance, wherein it is characterized that the clearance between the particular magnetic pole and its corresponding driven rotor is increased when the magnetic circuit is shorter or the magnetic resistance is smaller between the two magnetic poles of the same pair, or is decreased when the magnetic circuit is longer or the magnetic resistance is larger between the two magnetic poles of the same pair, whereby to cause the clearance appears asymmetrical along the symmetrical positions at the two sides of the magnetic axis, thereby the magnetic force lines on the pole surface of the magnetic pole can be maintained uniformly distributed and is characterized to let the magnetic force line distribution at the two sides of the magnetic pole appear symmetrical, whereby to meet the electrical machine requirement by matching with the narrower inter-pole magnetic circuit, provides a new method to effectively dissipate the accumulated heat inside the electrical machine, as well as by utilizing the intercrossed lamination concept, while maintaining the magnetic force line distribution status of the conventional electrical machine magnetic circuit and the aforesaid easy heat dissipating narrower inter-pole structure, whereby to provide the field magnetic circuit structure with radial ventilation holes and to have the patch-up type iron core at the same time, thereby to have the advantage of lowering down the casting die and machining costs without hindering its electrical machine characteristics. |
