Dress, the permanent magnet guided tooling be equipped with the one-to-one guide groove in permanent magnet installation position in rotor core, it is each
The permanent magnet guided tooling of the guide groove side is equipped with mistake proofing permanent magnet.
The guide groove arranges on permanent magnet guided tooling in the regular polygon of even number of sides, includes two on every one side
A guide groove.
Embedded groove there are one being set on inboard permanent magnet guided tooling in the middle part of each guide groove, the mistake proofing permanent magnetism
Body is embedded in embedded groove.
Multiple through-holes are additionally provided in the rotor core, the permanent magnet guided tooling is equipped with multiple a pair of with through-hole one
The location hole answered.
The rotor core inner ring is provided with keyway, and is fixed on main shaft by key, in the middle part of the permanent magnet guided tooling
Open the sets of holes more than main shaft outer diameter there are one internal diameter.
The utility model has the beneficial effects that：The mistake proofing of permanent magnet installation is realized, the direction according to permanent magnet stress is
It can determine whether mistake, to ensure the overall performance of motor, avoids making installation direction to effectively prevent permanent magnet anti-loaded
At do over again, the economic losses such as rotor retirement, without being forced into permanent magnet or testing the direction of permanent magnet one by one when installation, effectively
Guarantee efficiency of assembling.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the using state structure diagram of the utility model；
Fig. 3 is the structural schematic diagram of rotor core in the utility model.
Specific implementation mode
Referring to figs. 1 to 3, a kind of rotor permanent magnet of the utility model installs error prevention device, including is arranged in rotor
The permanent magnet guided tooling 2 of 1 one end of iron core, 1 inner ring of the rotor core is provided with keyway 13, and is fixed on main shaft 3 by key,
The middle part of the permanent magnet guided tooling 2 is opened there are one the sets of holes 24 that internal diameter is more than 3 outer diameter of main shaft, so as to by permanent magnet guided tooling
2 navigate to one end of rotor core 1 from main shaft 3.
12 permanent magnet installation positions 11 for penetrating through its both ends are equipped on the outside of 1 inner ring of the rotor core, this 12 forever
11 each two of magnet installation position on one side be in regular hexagon arrange, the permanent magnet guided tooling 2 be equipped with in rotor core 1
11 one-to-one guide groove 21 of permanent magnet installation position, i.e., it is in regular hexagon that 12 also are provided on permanent magnet guided tooling 2
The guide groove 21 of arrangement also includes often two guide grooves 21 on one side；In addition, 21 middle part of each guide groove is inboard
Permanent magnet guided tooling 2 on be additionally provided with an embedded groove, mistake proofing permanent magnet 22 is inlaid in the embedded groove, the mistake proofing is forever
Magnet 22 is opposite with the magnetic pole of permanent magnet to be installed.Permanent magnet to be installed is inserted by the guide groove 21 on permanent magnet guided tooling 2,
According to homopolar-repulsion, heteropolar attracting principle, if what is be inserted into is permanent magnet in the right direction, while human hand is let go, the
One piece of permanent magnet can be under the repulsion of mistake proofing permanent magnet 22 automatically into the permanent magnet installation position 11 in rotor core 1, subsequently
The suction of permanent magnet that is then first inserted into of permanent magnet be automatically drawn into；On the contrary, if the permanent magnet anisotropy being inserted into, permanent magnetism
Cognition is sucked or is come out by the permanent magnet repulsion being first inserted into permanent magnet installation position 11 by mistake proofing permanent magnet 22, to realize forever
The mistake proofing of magnet installation can determine whether installation side without firmly removing push-in permanent magnet when installation according to the direction of permanent magnet stress
To whether mistake, to effectively preventing permanent magnet anti-loaded.
Further, multiple through-holes 12 are additionally provided in the rotor core 1, through-hole 12 is used for after inserting permanent magnet
The rotor stop plate that both ends are fixed by stud, to prevent built-in permanent magnet axial float, and permanent magnet is oriented to work
It fills and also is provided with multiple and 12 one-to-one location hole 23 of through-hole on 2, this is to position for convenience, and work is oriented to placing permanent magnet
Through-hole 12 and location hole 23 are passed through by stud when filling 2, you can permanent magnet guided tooling 2 of having good positioning, in order to subsequently forever
Magnet is packed into operation.Specifically, the through-hole 12 is arranged at the interior angle for the regular hexagon that permanent magnet installation position 11 is constituted, and sets altogether
Six are set, it is six that location hole 23, which is also correspondingly arranged, more balanced to be distributed, and rotor stop plate is fixed more to be stablized.
The above, the only better embodiment of the utility model, but the utility model is not limited to above-described embodiment,
As long as it reaches the technique effect of the utility model with any same or similar means, it should all be included in the protection of the utility model
