Abstract
The utility model discloses a rotor structure of an asynchronously-started permanent magnet synchronous motor. The structure comprises the asynchronously-started permanent magnet synchronous motor, a rotor sheet and a plurality of rotor slots, wherein the rotor sheet is arranged in the asynchronously-started permanent magnet synchronous motor, and the plurality of rotor slots are irregularly distributed on the outer periphery of the rotor sheet. With adoption of the aforementioned mode, the rotor structure provided by the utility model has the capabilities of reducing the resistance of a rotor by using the irregularly-distributed rotor slots, being beneficial for enabling the rotor to be pulled into synchronism, maximally blocking off the flux leakage phenomenon of a permanent magnet, and allowing the flexible design of the shape of the rotor slots, thereby enabling the permanent magnet to have higher utilization efficiency.
Description
Technical field
The utility model relates to the motor designs field, particularly relates to a kind of rotor structure of asynchronous starting permanent magnet synchronous motor.
Background technology
Two traditional 4 pole asynchronous starting permanent magnet synchronous motor rotor punchings generally are that the punching outer rim is uniform common grooved, and defective is that rotor resistance is too large, bad every the magnetic effect, thereby the obstruction rotor pulls in or affects electric efficiency.
The utility model content
The technical problem that the utility model mainly solves provides a kind of rotor structure of asynchronous starting permanent magnet synchronous motor, can effectively reduce the resistance of rotor, farthest blocks the leakage field phenomenon of permanent magnet.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the rotor structure that a kind of asynchronous starting permanent magnet synchronous motor is provided, comprise: asynchronous starting permanent magnet synchronous motor, be located at the rotor punching in the described asynchronous starting permanent magnet synchronous motor, described rotor punching neighboring is inhomogeneous is laid with a plurality of rotor.
In preferred embodiment of the utility model, described rotor shape comprises circle, keyway type, rectangle and irregular shape.
In preferred embodiment of the utility model, described asynchronous starting permanent magnet synchronous motor is three-phase two 4 pole asynchronous starting permanent magnet synchronous motors.
In preferred embodiment of the utility model, described asynchronous starting permanent magnet synchronous motor is single-phase two 4 pole asynchronous starting permanent magnet synchronous motors.
The beneficial effects of the utility model are: the rotor structure of the utility model asynchronous starting permanent magnet synchronous motor utilizes non-uniform multiple rotor, subtracts trochantinian resistance, is conducive to rotor and is pulled into synchronously; Farthest block the leakage field phenomenon of permanent magnet; Can also design neatly the rotor shape, thereby so that permanent magnet there is higher utilization ratio.
