摘要

Such as the subject innovation is derived gidonghyeong permanent magnet relates to an alternating current high-speed synchronous motor, in the prior art, often a structural or that the assembly method is complicated, neulrineunde limiting factor the number of magnetic poles arranged in the magnet rotor, the synchronization deviation due to the magnetic forces damage there was a problem. And the subject innovation is in view of this, die cast aluminum parts having an induction-type rotor 70, the first core 51, first permanent magnet of circular 41, the second core 52, a second permanent magnet (42 ) and the third core 53 is once fixed by fixing means fitted in turn to the rotor shaft 30, the rotor shaft 30, the motor case 10 to be rotatable by a bearing (31a, 31b) the installation, the said first and second permanent magnets 41, 42 the polarity of the surface facing each other and arranged to have the same polarity, the first, each thickness of the third core 51, 53, a second and a half of the thickness of the core 52, the first - the third core (51 - 53) is projected in the first and second further predetermined length outside the permanent magnets (41, 42) times are of the electronic plurality of protrusions forming the stimulation of, the projections of the first core 51 and third core 53 and a match is found in the same direction, the protruding portion of the second core 52 has the first and 3 is symmetrical with the protrusion of the core (51, 53) By providing a rotor structure arranged in a counterintuitive to prevent the adhesive preparation, at a starting time after being activated by the inductive rotor start-up is able to keep up with high-speed synchronization by the magnet rotor.
