The invention relates to a method and system for measuring the magnetic resistance characteristics of salient poles and yoke parts of a switched reluctance motor. According to the method and system, a single-phase winding is turned on through the geometrical symmetry of the switched reluctance motor, magnetic linkages of all phases are measured through specific two-phase windings positively connected in series and negatively connected in series, and the magnetic resistance characteristic curves of the stator-and-rotator salient poles and the yoke parts for the magnetic flux can be obtained based on the magnetic circuit method. According to the method and system, additional mechanical measuring platforms and additional test circuits are not required, measurement can be completed in the industrial site through a power converter of a switched reluctance motor system, the process is simple and rapid, and high practicability is achieved; the parameters of the motor structure and the magnetization characteristic of a silicon steel sheet do not need to be foreknown, and universality is high; an equivalent magnetic network motor model considering the interphase mutual-inductance influence can be built, and the method and system are of great significance in improving the position-sensor-free control performance and the smoothness torque control performance and popularizing the application field of the switched reluctance motor system.
