摘要： A motor rotor includes an annular body and a magnetic body installed on an inner lateral surface of the annular body. The magnetic body has a first curved surface and a second curved surface opposing the first curved surface. The magnetic body props against the inner lateral surface of the annular body via the first curved surface. The first curved surface has a first curvature less than a second curvature of the second curved surface. Because the magnetic body of the motor rotor has an uneven thickness, and an air gap interval formed between the motor rotor and the stator also has an uneven width, forces applied to a region where the magnetic forces change directions are smooth. Therefore, the vibration of the whole motor is reduced, and the noises are suppressed effectively.
摘要翻译：马达转子包括环形体和安装在环形体的内侧表面上的磁体。磁体具有与第一弯曲表面相对的第一弯曲表面和第二弯曲表面。磁体通过第一弯曲表面抵靠环形体的内侧表面。第一弯曲表面具有小于第二曲面的第二曲率的第一曲率。由于电动机转子的磁体具有不均匀的厚度，并且在电动机转子和定子之间形成的气隙间隔也具有不均匀的宽度，所以施加到磁力变化方向的区域的力是平滑的。因此，整个电动机的振动减小，噪声被有效地抑制。
