本发明属于电机制造技术领域，公开了一种转子结构及永磁激磁电机。其中，该转子结构包括转子轭，呈环形阵列交替分布于转子轭上的多个第一转子齿与多个第二转子齿，相邻第一转子齿与第二转子齿之间设有第一转子永磁体，第二转子齿上设有第二转子永磁体。这样，通过第二转子齿代替了部分永磁体的用量，减小了永磁体的用量，提高了单位体积下转子齿与永磁体的配比密度，进而提高了永磁体的利用率，此外，通过第二转子齿相对两侧的第一转子永磁体可实现聚磁效应，大大提高了电机的磁负荷，使得单位磁体体积的输出转矩得到较大的提升。

The invention belongs to the technical field of motor manufacturing, and discloses a rotor structure and a permanent magnet exciting motor. The rotor structure comprises a rotor yoke, a plurality of first rotor teeth and a plurality of second rotor teeth which are alternately distributed on the rotor yoke in an annular array, wherein first rotor permanent magnets are arranged between the adjacentfirst rotor teeth and the adjacent second rotor teeth; and a second rotor permanent magnet is arranged on each second rotor tooth. Thus, the using amount of a part of permanent magnets is replaced through the second rotor teeth, the using amount of the permanent magnets is reduced, the matching density of the rotor teeth and the permanent magnets in unit volume is improved, and then the utilization rate of the permanent magnets is improved; and moreover, a magnetism gathering effect can be realized through the first rotor permanent magnets on two opposite sides of the second rotor teeth, the magnetic load of the motor is improved greatly, and the output torque in unit magnet volume is greatly promoted.
