Permanent magnet motor rotor with self-starting function

A permanent magnet motor rotor with a self-starting function comprises an iron core (5) formed by stacking silicon steel sheets, an even number of convex teeth (7) symmetrically extending from the outer circle of the iron core, tile-shaped permanent magnets (4) arranged among the convex teeth, and a cylindrical sheath (3) sleeved on the outer surfaces of the permanent magnets, and is characterized in that grooves (8) are arranged on the convex teeth, flow guide strips (6) are arranged in the grooves, and the flow guide strips (6) are arranged in the grooves. Collector rings (2) are respectively connected to two ends of the flow guide strip. According to the working principle, in the starting process of the permanent magnet motor, the rotating magnetic field of the stator cuts the flow guide strips, induction current is generated in the flow guide strips, and then electromagnetic torque is generated to enable the rotor to rotate. The self-starting permanent magnet motor has the beneficial effect that when the
