Abstract
The utility model discloses stator and rotor structures of a high-starting-torque asynchronous starting three-phase permanent-magnet synchronous motor. The stator and rotor structures comprise a stator core and a cage type rotor, the shape of a stator groove section of the stator core is a pyriform groove structure, and magnetic poles of permanent magnets of the cage type rotor are V-shaped structures and are uniformly arranged in V-shaped grooves in the cage type rotor in a built-in radial structure. The stator and rotor structures of the high-starting-torque asynchronous starting three-phase permanent-magnet synchronous motor are advantageous in that the shape of the stator groove section of the stator core is the pyriform groove structure so that the loss produced by the magnetic field in the stator core can be effectively reduced; the magnetic poles of the permanent magnets of the rotor are the V-shaped structures and are uniformly arranged in the V-shaped grooves in the cage type rotor in a built-in radial structure, starting is realized through the asynchronous torque generated by windings of the cage type rotor, and after regular operation, constant torque is generated by the interaction of the V-shaped magnetic poles of the permanent magnets of the rotor and a rotating field generated by stator windings so that the work efficiency of the motor can reach 94.0% to the maximum, and the maximum starting torque is 4.5 times as much as the rated torque.
