Abstract
The invention discloses a self-starting permanent magnet synchronous motor rotor comprising a squirrel cage, a rotor iron core and permanent magnets. The permanent magnets of which the cross section is tile-shaped are evenly distributed in arc-shaped grooves arranged on the circumferential surface of the rotor iron core. The cage strips of the squirrel cage are evenly distributed in the rotor iron core between the permanent magnet end surfaces. The two ends of each cage strip are respectively connected with the two end rings of the squirrel cage so as to form an internal squirrel cage. A cylindrical sheath sleeves the external circumferential surface of the rotor iron core and the external circumferential surface of the permanent magnets of which the cross section is tile-shaped. Axial long holes are evenly distributed on the circumferential surface of the sheath. A part of external cage strips between the long holes are opposite to the squirrel cage strips. An external squirrel cage is formed by the sheath. The sheath is made of conductive and non-magnetic material. The self-starting permanent magnet synchronous motor rotor has substantial advantages of high operation efficiency, energy conservation, convenient magnetizing and great manufacturability.
Description
Technical field:
The present invention relates to a kind of motor, particularly self-start permanent magnet synchronous motor rotor.
Background technology:
Existing self-start permanent-magnet synchronous motor, permanent magnet is located in the rotor core between cage bar and rotating shaft, there are two defects in this structure, distant due between permanent magnet and stator, when motor start-up enters normal course of operation, operational efficiency is lower, and consume energy large defect, two is arrange permanent magnet in rotor core, and manufacturability is poor.
Summary of the invention:
The present invention seeks to design a kind of operational efficiency high, the self-start permanent magnet synchronous motor rotor of energy-conservation and good manufacturability.
The technical scheme realizing the object of the invention is, self-start permanent magnet synchronous motor rotor, comprise mouse cage, rotor core and permanent magnet, it is characterized in that: cross sectional shape is that the permanent magnet of watt shape is distributed in the deep-slotted chip breaker on rotor core side face, the cage bar of described mouse cage is distributed in the rotor core between described permanent magnet end, the two ends of described each cage bar are connected to form interior mouse cage with two end ring of mouse cage respectively, tubular sheath is set in rotor core outer peripheral face and cross section is on the permanent magnet outer peripheral face of watt shape, the side face of described sheath is evenly equipped with axial elongated hole, the outer cage bar of part between elongated hole is relative with squirrel-cage bar, described sheath forms outer mouse cage, described sheath is for conduction and non-magnet_conductible material is made.Described sheath is that brass or stainless steel material are made.
The present invention has that operational efficiency is high, energy-conservation, magnetize remarkable advantage that is convenient and good manufacturability compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is the perspective view of self-start permanent magnet synchronous motor rotor of the present invention; Fig. 2 is sheath perspective view; Fig. 3 is the A-A profile of Fig. 1.
Embodiment:
The present invention has following embodiment, as Figure 1-3, the axial deep-slotted chip breaker that uniform four permanent magnets 5 that are watt shape with cross sectional shape match on the side face of rotor core 7, rotor core outer rim between described four deep-slotted chip breaker end faces is evenly equipped with three squirrel-cage bars 6, the two ends of above-mentioned 12 squirrel-cage bars are connected to form interior mouse cage with two end ring respectively, on the outer peripheral face of described rotor core, the permanent magnet in above-mentioned rotor core deep-slotted chip breaker is fixed by sheathed sheath 1, prevents being centrifuged power when High Rotation Speed and throws away.The side face of described sheath is evenly equipped with the elongated hole 2 of 24 axis, the outer cage bar 3 of the rectangular formation between these 24 elongated holes, 12 cage bars in described outer cage bar respectively with between permanent magnet end in squirrel-cage bar relative.Described sheath by conducting electricity non-magnetic material make, as brass or stainless steel etc.Rotating shaft 4 drives rotor core to rotate by key.
The polarity of above-described embodiment motor is four poles, also can be sextupole, the ends of the earth or 12 poles.
The present invention is owing to being located at rotor core outer rim place by permanent magnet, with stator close together, meanwhile, jacket body is evenly equipped with outer cage bar and mutually superposes with squirrel-cage bar and there is the effect starting effect and superpose, thus start-up and operation Be very effective and the advantage that is convenient and good manufacturability that magnetizes.
