Induction starting type permanent magnet AC high-speed synchronous motor

摘要

This research is about the induction motor of high-speed AC permanent magnet motor. The structure of arranging magnets on the rotor or its assembly method is complex, there are many restrictions to increase the number of stimuli, and there are problems such as the separation of the motor caused by magnetic damage.Taking these factors into account, the induction rotor (70) with aluminum multi corner andFirst nose (51),The first permanent magnet (41) of the circle,Second nose (52),The second permanent magnet (42) and the third koa (53) are successively inserted into the rotating shaft (30) and fixed in a fixed manner,The rotor shaft (30) is arranged on the die housing (10) by the bearings (31a, 31b),The first and second permanent magnets (41),(42) arranging opposite polarity in the same polarity,Section 1 and 3 (51)The thickness of each layer of (53) is 1 / 2 of the thickness of the second Korea (52),Compared with the first and second permanent magnets (41, 42), the length of the first and third families (51-53) protrudes to the outside, forming multiple protruding parts of rotation stimulation,The projections of the first nose (51) and the third nose (53) are in the same direction,In order to avoid overlapping, a rotating substructure is provided to avoid cross arrangement.At the same time, it is driven by the induction rotor, and the high-speed engine can be driven by the magnet rotor after the motor.
