In view of the above defects in the prior art, the present invention provides a built-in hybrid permanent magnet memory motor with local magnetic circuits in parallel, which solves the problem of limited size of permanent magnets, low utilization ratio, severe cross-coupling demagnetization of high-coercivity permanent magnets on low-coercivity permanent magnets, and unstable operating point of the low-coercivity permanent magnets in the existing built-in permanent magnet motor with magnetic circuits in parallel.

The technical solution of the present invention is as follows: a built-in hybrid permanent magnet memory motor with local magnetic circuits in parallel includes a hybrid permanent magnet rotor, a stator, armature windings and a rotating shaft. The armature windings are disposed on the stator, and the stator is disposed outside the hybrid permanent magnet rotor. The hybrid permanent magnet rotor includes a rotor core, first permanent magnets, second permanent magnets and V-shaped magnetic barriers. The rotor core is disposed outside the rotating shaft, the V-shaped magnetic barriers are disposed inside the rotor core, the V-shaped magnetic barriers with openings facing outwards are equally distributed in a circumferential direction of the rotor core, the first permanent magnet is disposed in the opening of the V-shaped magnetic barrier, the second permanent magnet is disposed between the two adjacent V-shaped magnetic barriers, a coercivity of the first permanent magnet is greater than a coercivity of the second permanent magnet, and cross sections of the first permanent magnets and the second permanent magnets are in a straight line.

Further, a thickness of a bottom of the V-shaped magnetic barrier is greater than a thickness of a side surface.
