Description
Technical field
The present invention relates to technical field of motors, and in particular to a kind of magnet steel for constituting rotor.
Background technique
Permanent magnet synchronous motor rotor magnetic steel is in usually tile at present, this kind of magnet steel is called magnetic shoe, and magnetic shoe is usually one
One piece of block fastens with glue onto rotor core outer surface, and the magnetic shoe on general middle slowspeed machine can use such arrangement side
Formula, and high-speed motor will also need additionally to put on the magnetic shoe sleeve of annular outside magnetic shoe again after bonding, to prevent magnetic shoe from using
It falls off in journey.
Wherein, in magnetic shoe and motor bonding process, usually first glue is coated on the medial surface of magnetic shoe, is then attached
To the surface of rotor core, due to the magnetic force between the magnetic force and two magnetic shoes between magnetic shoe and rotor core, magnetic shoe patch
After on to rotor core, need manually to press until glue tentatively bonds magnetic shoe with rotor core, the installation of such magnetic shoe is imitated
Rate is low, and increases the labor intensity of workers；In addition, the pole N and the pole S of magnetic shoe are arranged after needing worker to differentiate, once
The arranged direction mistake of magnetic shoe, it will cause motors to operate.
Summary of the invention
It is an object of the present invention to provide a kind of magnet steel for facilitating installation, improve the assembling quality and dress of rotor
With efficiency.
To achieve the goals above, the technical solution of use are as follows: a kind of rotor magnetic steel, including annular magnetic steel unit, at least
Two magnet steel unit axial end faces are bonded to each other arrangement and constitute tubular magnet steel ontology.
Compared with prior art, technical effect of the invention are as follows: this makes it possible to directly successively cover annular magnetic steel unit
If worker operation is convenient to rotor core, the installation effectiveness of magnet steel ontology is improved, the application can be according to rotor core not
Same axial length, arranges the magnet steel unit of respective numbers, without in addition manufacturing and designing magnet steel.In addition, even in high speed electricity
Machine upper magnetic steel ontology can not also fall off.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of magnet steel ontology；
Fig. 2 is the explosive view of rotor；
Fig. 3 is the half sectional view of rotor；
Fig. 4 is the A-A cross-sectional view in Fig. 3.
Specific embodiment
A kind of rotor magnetic steel, including annular magnetic steel unit 11, at least two magnet steel units, 11 axial end face are bonded to each other cloth
It sets and constitutes tubular magnet steel ontology 10.
Annular magnetic steel unit 11 is directly successively sheathed on rotor core 20 by worker, and worker operation is convenient, improves magnetic
The installation effectiveness of steel ontology 10, the axial length that the application can be different according to rotor core 20, arranges the magnet steel of respective numbers
Unit, without in addition manufacturing and designing magnet steel.In addition, even can not also fall off in high-speed motor upper magnetic steel ontology.
It is circumferentially rotated to effectively limit magnet steel unit 11, offers limit on 11 inner wall of magnet steel unit of the annular
Slot 12, the flute length direction of the limiting slot 12 are axial consistent with magnet steel unit 11；
Raised line 21, the length direction of raised line 21 and the axial direction of rotor core 20 are disposed on the outer wall of the rotor core 20
Unanimously, raised line 21 and the cooperation limitation 11 relative rotor iron core 30 of magnet steel unit of limiting slot 12 of magnet steel unit 11 circumferentially rotate.Separately
Outside, worker is not necessarily to recognize the magnetic pole of magnet steel unit 11, directly by the raised line of the limiting slot 12 of magnet steel unit 11 and rotor core 20
21 alignment insertions.
The limiting slot 12 is disposed at least two along the circumferential upper uniform intervals of magnet steel ontology 10, further reliably limits
11 circumferential position of magnet steel unit.
Illustrate the rotor that the magnet steel of the application is constituted below, shaft 30, rotor are pressed in the middle part of rotor core 20
The magnet steel ontology 10 of annular is arranged with outside iron core 20.
Wherein annular magnet steel ontology 10 can be bonded on rotor core 20 with glue, but such mode can not be reliable
Ground is fixed by rotor core 20 and magnet steel ontology 10, and therefore, the application limits the axial direction of magnet steel ontology 10 using following scheme
Position.
During annular magnetic steel unit 11 is successively sheathed on rotor core 20, two adjacent magnet steel units 11 are mutual
Repel and can not be close to, therefore in order to limit the axial position of annular magnetic steel unit 11, turns at 20 both ends of rotor core
The end plate 40 of annular is arranged on axis 30 respectively, the outer diameter size of end plate 40 is located between the inside and outside diameter size of magnet steel ontology 10,
Two end plates 40 are pressed against respectively on the both ends of magnet steel ontology 10.
Pressure ring 50 is pressed in the shaft 30, the end plate 40 between pressure ring 50 and the end face of magnet steel ontology 10,
End plate 40 is pressed on the end face of magnet steel ontology 10 by pressure ring 50.End plate 40 and 30 clearance fit of shaft, end plate 40 and shaft 30
It after assembly, is interference fitted by pressure ring 50 and shaft 30, end plate 40 reliably can be pressed on magnet steel ontology 10 by pressure ring 50
On end face.
