Description
Technical field
This utility model belongs to the rotor core field containing permanent magnet, and in particular to a kind of oblique pole knot of rotor sectional type
Structure.
Background technology
In recent years, with the development of Power Electronic Technique and motor control technologies, motor is agriculture, industrial, manual
The fields such as industry apply quite varied, and motor plays the important and pivotal role in socio-economic development, improve motor
Running quality, has positive role to China's economic development.In middle-size and small-size motor, rotor core is often fabricated to skewed slot,
Skew one or half tooth are away from this version can effectively reduce motor harmonic wave oblique pole, so as to reduce noise
And the effect of vibrations, further increase the running quality of motor.
The cast-aluminum rotor that traditional common motor is adopted, iron core can be laminated by the dislocation of punching and realize oblique pole.Such as patent
Number a kind of rotor structure of three-phase permanent-magnetic synchronous motors is disclosed for the Chinese patent literature of CN201220476513.6, its master
Want structure and have aluminum cast groove and internal punching to have the stalloy of arc magnet steel groove by excircle punching for rotor that skew laminates cast aluminium vertically
Form, rotor chute and arc skewed slot are formed on rotor；Magnet steel is respectively arranged in each arc skewed slot of the rotor, institute
It is bonding rare earth permanent-magnetic material to state magnet steel, and in oblique shoe, a watt body for the oblique shoe has radian, two groups of opposite side difference of watt body
It is parallel, and two groups of opposite side are mutually inclined.
The permasyn morot feature of this structure is that permanent-magnet steel is pasted or inlayed on rotor core, by magnet steel sheet
Body produces magnetic field, improves motor running efficiency.But due to iron core of rotor of motor it is generally more elongated, so magnet steel need
It is divided into equal several sections to install, if rotor core is laminated together using whole section, the pressure for laminating needs is larger, to turning
The intensity requirement of axle and end plate is also higher.In addition, it is identical with the magnetic steel magnetic pole pasted in an angle or inlay, magnetic is pasted in the later stage
During steel, because there is repulsive force with interpolar, pole is unfavorable for assembling magnet steel.
To solve the problems, such as that magnet steel is difficult to assemble, prior art adopts stagewise core structure, and its principle is that rotor is whole
Iron leg core is divided into some equal portions, and per section first compresses and uses rivet afterwards, after pasting or having inlayed magnet steel, another and by whole iron leg core
In rotating shaft, so as to the magnetic pole for ensureing equal angular is identical.Generally adjacent two iron legs core is by being rotated by 90 ° or passing through upset
To avoid manufactured head, but whole section of rotor core after so assembling cannot realize the effect of oblique pole, i.e., effectively can not drop
Low motor harmonic wave, so as to noise and vibrations cannot be reduced.
Utility model content
This utility model is intended to provide a kind of rotor sectional type oblique pole structure, to optimize original permanent-magnet motor rotor assembling
Technique, effectively reduces motor harmonic wave, reduces noise and the vibrations of motor, improves the running quality of motor.
The oblique pole structure of a kind of rotor sectional type in this programme, including rotating shaft and rotor core, are provided with axle on rotor core

Or it is inlaid with magnet steel；Aperture axis are located on same section of rotor core identical to the magnetic steel magnetic pole on line.
The know-why of this programme is that rotor core is divided into some sections, and reduction laminates pressure during rotor core, in order to avoid
Pressure is excessive and damage rotating shaft, first member plate and right end plate, while existing paste magnet steel or be embedded on rotor core, it is to avoid rear
When phase pastes or inlays magnet steel, because being difficult to assemble with the repulsive force of interpolar.Adjacent two-stage rotor iron core is mutually staggered, the
One section of rotor core is identical with the state of three-stage rotor iron core, the state phase of second segment rotor core and the 4th section of rotor core
Together, i.e., odd number section rotor core is the state that staggers relative to even number section rotor core, so that rotor reaches the effect of oblique pole；It is left
The effect of end plate and right end plate main stabilization rotor core.
RADIAL as herein described refers to the straight line along shaft hole diameter direction.
What this programme can be produced has the technical effect that：Adjacent two-stage rotor iron core is mutually staggered so that rotor core shape
Into oblique pole effect, and reduce pressure required when laminating rotor core, it is to avoid pressure is excessive to damage rotating shaft, first member plate and right-hand member
Plate, while first magnet steel being pasted or being embedded on rotor core, then rotor core is connected in turn in rotating shaft, is solved because of magnetic
Steel repulsive force and be difficult to the problem assembled.This programme optimizes original permanent-magnet motor rotor assembly technology, effectively reduces electronic
Machine harmonic wave, reduces noise and the vibrations of motor, and inventor successfully applies to this technology on new-energy automobile, according to reality
Checking, this technology can improve the conversion power of motor to 96%, greatly improve the running quality of motor.
