Abstract
The utility model discloses a self -start permanent magnet synchronous motor rotor, including squirrel cage, rotor core and permanent magnet, in the cross sectional shape be the arc wall of permanent magnet equipartition on rotor core is global that the tile appeared, the cage strip equipartition of squirrel cage is in among the rotor core between the permanent magnet terminal surface, the both ends of each cage strip respectively with the both ends linkage of squirrel cage connect form in the squirrel cage, on the permanent magnet outer peripheral face that appears in rotor core outer peripheral face and cross -section is established for the tile to cylindric sheath cover, the global equipartition of going up of sheath has axial slot hole, and the some outer frame strips between the slot hole are relative with the squirrel -cage bar, the sheath forms outer squirrel cage, the sheath is made for electrically conductive not magnetic materials. The utility model has the advantages of operating efficiency high, energy -conserving, magnetize convenience and good the showing of manufacturability.
Description
Technical field:
This utility model 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 relatively low, and consume energy big defect, two is to arrange permanent magnet in rotor core, and manufacturability is poor.
Summary of the invention:
This utility model purpose is that a kind of operational efficiency of design is high, the energy-conservation and self-start permanent magnet synchronous motor rotor of good manufacturability.
The technical scheme realizing this utility model purpose is, self-start permanent magnet synchronous motor rotor, including Mus cage, rotor core and permanent magnet, it is characterized in that: cross sectional shape is that the permanent magnet of shoe is distributed in the arcuate groove 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 Mus cage in formation respectively with two end ring of mouse cage, tubular sheath is set on rotor core outer peripheral face and permanent magnet outer peripheral face that cross section is shoe, axial elongated hole it is evenly equipped with on the side face of described sheath, the outer cage bar of part between elongated hole is relative with squirrel-cage bar, described sheath forms outer Mus cage, described sheath for conduction non-magnet_conductible material make.Described sheath is pyrite or stainless steel material is made.
This utility model has that operational efficiency is high, energy-conservation compared with the prior art, magnetize the convenient and remarkable advantage of good manufacturability.
Accompanying drawing illustrates:
Fig. 1 is the perspective view of this utility model self-start permanent magnet synchronous motor rotor；Fig. 2 is sheath perspective view；Fig. 3 is the A-A profile of Fig. 1.
Detailed description of the invention:
This utility model has following embodiment, as Figure 1-3, uniform four axial arcuate grooves matched with the permanent magnet 5 that cross sectional shape is shoe on the side face of rotor core 7, it is evenly equipped with three squirrel-cage bars 6 in rotor core outer rim between described four arcuate groove end faces, the two ends of above-mentioned 12 squirrel-cage bars are connected mouse cage in formation respectively with two end ring, on the outer peripheral face of described rotor core, the permanent magnet in above-mentioned rotor core arcuate groove is fixed by sheathed sheath 1, prevents from being thrown away by centrifugal force when high speed rotating.Being evenly equipped with 24 axial elongated holes 2 on the side face of described sheath, the strip between these 24 elongated holes forms outer cage bar 3, and 12 cage bars in described outer cage bar are relative with the interior squirrel-cage bar between permanent magnet end respectively.Described sheath is by conducting electricity and non-magnetic material is made, such as pyrite or rustless steel etc..Rotating shaft 4 drives rotor core to rotate by key.
The polarity of above-described embodiment motor is quadrupole, it is also possible to be six types of severe debility disease, the ends of the earth or 12 poles.
This utility model is owing to being located at rotor core by permanent magnet
At outer rim, close together with stator, meanwhile, jacket body is evenly equipped with outer cage bar and is overlapped mutually with squirrel-cage bar and has and start the effect that effect superposes, thus start notable with operational effect in the magnetize convenient and advantage of good manufacturability.
