The effect of this creation is:

1. Compared with the previous case, the number of rotors in this creation can be reduced by about one-half, and the use of alumina magnets is also reduced by about one-half, which is cheap and low in material cost.

2. Since the magnetic conductive sheet has magnetic permeability, when the rotor is slightly larger than one-half of the number of rotors in the foregoing case, the magnetic permeability of the magnetic conductive sheet can still allow the magnetic conductive sheet and the rotor to be The distribution of the magnetic lines of force is relatively concentrated, so that the magnetic conductive sheet can partially replace the effect of the bauxite magnet on the original rotor, and the material cost of the above-mentioned previous case and the present creation are concentrated on the alumina magnet, so even the creation of this The induced electromotive force will be slightly lower than the previous case, but this creation reduces the use of slightly more than one-half of the alumina magnet, which greatly reduces the material cost of the creation. Therefore, the creation has a higher cost performance.
