<p>A ferrite three-section three-phase permanent magnet motor is provided, in which a stator iron core has a three-section structure made of soft magnetic ferrite, and each of the three phase windings A,B,C occupies one section; the slot number of the stator iron core is Z, the number of magnetic poles of the rotor is 2P, Z=2P=2X, in which X=21,22,23,...100; a plurality of slots used for embedding winding are formed in front and back, on the left and right of each tooth; each phase has 2X concentrated windings which are circularly arranged in accordance with the order of A->/A; the phase B and phase C have the same structure and the space phases of the three phase A, B, C stator iron cores differ from each other at 120º electric angle. The motor has advantages of small winding end, small positioning torque, less copper loss and iron loss et al.</p> |
