1. A salient pole type hybrid excitation motor, comprising a stator assembly and a rotor assembly, wherein the stator assembly has a stator inner cavity, and the rotor assembly is located in the stator inner cavity, the rotor assembly comprising:
a magnetic yoke;
an electromagnetic rotor constructed in an annular shape and sleeving the magnetic yoke, the electromagnetic rotor being provided with, at intervals on an annular peripheral surface thereof, a plurality of radial salient poles projecting radially;
at least one set of permanent magnet rotor sleeving the magnetic yoke and arranged on one side of the electromagnetic rotor, each set of the permanent magnet rotor comprising:
a permanent magnet rotor core constructed in an annular shape and sleeving the magnetic yoke, a plurality of permanent magnet steels being installed on the permanent magnet rotor core; and
a plurality of axial salient pole blocks corresponding to the plurality of radial salient poles of the electromagnetic rotor and installed on an outer side of the permanent magnet rotor core, the axial salient pole blocks being arranged alternately with the plurality of radial salient poles of the electromagnetic rotor, the plurality of axial salient pole blocks being matched with the plurality of radial salient poles of the electromagnetic rotor, and a polarity of the permanent magnet steels corresponding to the axial salient pole blocks being opposite to that of the permanent magnet steels corresponding to the radial salient poles of the electromagnetic rotor.
