Abstract
The present disclosure relates to a rotor assembly and a consequent-pole motor, and the rotor assembly includes an iron core and a plurality of permanent magnets. The iron core is provided with a plurality of mounting grooves for accommodating permanent magnets distributed along a circumferential direction of the iron core. One side of each of the mounting grooves adjacent to an end of an outer edge of the iron core is provided with a second air slot which is located in a consequent-pole region. The second air slot is communicated with the mounting groove. The second air slot can, on one hand, prevent magnetic lines emitted from the permanent magnet from short-circuiting through an end of the permanent magnet, so as to decrease the magnetic flux leakage, and on the other hand, adjust an orientation of the magnetic lines in the consequent-pole region, so as to weaken torque fluctuation.
