Abstract
The invention discloses a rotor structure of an asynchronously-started permanent magnet synchronous motor, which 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. Due to adoption of the mode, the rotor structure has the capabilities of reducing the resistance of a rotor by using the irregularly-distributed rotor slots, being beneficial to a rotor to be pulled into synchronism, furthest blocking the flux leakage phenomenon of the permanent magnet and flexibly designing the rotor slot shapes, thereby enabling the permanent magnet to have higher utilization efficiency.
Description
Technical field
The present invention relates to the motor designs field, particularly relate 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 the punching outer rims for being uniformly distributed with common grooved, and defective is that rotor resistance is too big, bad at a distance from the magnetic effect, thereby hinder rotor to pull in or influence electric efficiency.
Summary of the invention
The technical problem that the present invention 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 present invention 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 said asynchronous starting permanent magnet synchronous motor, said rotor punching neighboring is uneven to be laid with a plurality of rotor.
In preferred embodiment of the present invention, said rotor shape comprises circle, keyway type, rectangle and non-regular shape.
In preferred embodiment of the present invention, said asynchronous starting permanent magnet synchronous motor is three-phase two 4 pole asynchronous starting permanent magnet synchronous motors.
In preferred embodiment of the present invention, said asynchronous starting permanent magnet synchronous motor is single-phase two 4 pole asynchronous starting permanent magnet synchronous motors.
。
The invention has the beneficial effects as follows: the rotor structure of asynchronous starting permanent magnet synchronous motor of the present invention utilizes the non-multiple rotor that is uniformly distributed with, and reduces the resistance of rotor, helps rotor and is pulled into synchronously; Farthest block the leakage field phenomenon of permanent magnet; Can also design the rotor shape neatly, thereby make permanent magnet that higher utilization ratio arranged.

The mark of each parts is following in the accompanying drawing: 1, rotor punching, 2, rotor.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of rotor structure of asynchronous starting permanent magnet synchronous motor comprises: asynchronous starting permanent magnet synchronous motor, be located at the rotor punching 1 in the said asynchronous starting permanent magnet synchronous motor.
Said rotor punching 1 neighboring is uneven to be laid with a plurality of rotor 2.Said rotor 2 shapes comprise circle, keyway type, rectangle and non-regular shape.
Perfect traditional common rotor that is uniformly distributed with is utilized the non-multiple rotor 2 that is uniformly distributed with, and rotor 2 is a difformity, reduces the resistance of rotor, helps rotor and is pulled into synchronously; Farthest block the leakage field phenomenon of permanent magnet.Can design rotor 2 shapes neatly, thereby make permanent magnet that higher utilization ratio arranged.
Said asynchronous starting permanent magnet synchronous motor is three-phase two 4 pole asynchronous starting permanent magnet synchronous motors.Said asynchronous starting permanent magnet synchronous motor is single-phase two 4 pole asynchronous starting permanent magnet synchronous motors.
Adopt identical materials and cost, higher efficient is arranged than similar motor; On single-phase or three-phase two 4 pole asynchronous starting permanent magnet synchronous motors, all can use.
The rotor structure of asynchronous starting permanent magnet synchronous motor of the present invention utilizes the non-multiple rotor 2 that is uniformly distributed with, and reduces the resistance of rotor, helps rotor and is pulled into synchronously; Farthest block the leakage field phenomenon of permanent magnet; Can also design rotor 2 shapes neatly, thereby make permanent magnet that higher utilization ratio arranged.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
