Axially asymmetric configuration for interior permanent magnet machine

An interior permanent magnet machine includes a rotor having a central axis and a plurality of axial segments. The axial segments include a first axial segment and a second axial segment positioned which are adjacent to each other in an axial direction. Each of the axially-spaced segments includes at least one pole defining a respective angular configuration characterized by respective first, second and third angles. The first axial segment defines a first set of angular configurations and the second axial segment defines a second set of angular configurations. The rotor is configured to have an axially asymmetric configuration such that the first set of angular configurations is different from the second set of angular configurations. 内置式永磁体电机包括转子，其具有中央轴线和多个轴向段。轴向段包括第轴向段和第二轴向段，其沿轴向方向邻近彼此定位。每个轴向间隔的段包括至少个极，限定特征为相应第、第二和第三角的相应角配置。第轴向段限定第组角配置，第二轴向段限定第二组角配置。转子被配置为具有轴向非对称配置，从而第组角配置与第二组角配置不同。
