Abstract

A rotor magnetic sheet with polarization deformation comprises the same number of outer layer magnetic sheets (20) and inner layer magnetic sheets (40). The outer layer magnetic sheets (20) and the inner layer magnetic sheets (40) are matched pairwise and are annularly and uniformly distributed around a shaft (5) of a wind-driven generator. The radial spacing between the outer layer magnetic sheets (20) and the inner layer magnetic sheets (40) is smallest in the middle, and becomes larger on two sides. The curve shapes of opposite side lines of the inner and outer magnetic sheets are further adjusted on the basis of polarization deformation, so as to obtain better magnetic field distribution.
