Description
Technical field
The present invention relates to permanent-magnetic synchronous motor rotor needed for new-energy automobile field or industrial circle, and in particular to one kind is mixed
Mould assembly permanent-magnet pole rotor.
Background technology
Existing permagnetic synchronous motor, rotor magnetic steel radial magnetic field have " one " type, " V " type, " W " type etc., and shortcoming is to be only capable of
One direction magnetic field is formed, unit volume magnet steel maximum cannot utilize in terms of torque output.
Existing permagnetic synchronous motor, the shortcomings that " 1 " type or other forms, tangential magnetic field that has of rotor magnetic steel tangential magnetic field be
Magnet steel easily demagnetizes in the case of high speed weak magnetic and high temperature.
The content of the invention
The purpose of the present invention is：The rotor structure of comprehensive magnet steel radial magnetic field and the rotor structure of magnet steel tangential magnetic field are each
The shortcomings that existing, both rotor structure forms are used in same motor, complementary respective shortcoming simultaneously so that motor is overall outer
Characteristic gets a promotion, and mitigates rotor weight, improves motor torque density.
The present invention is to provide a kind of mixed type permanent-magnet pole rotor to solve the technical scheme that above-mentioned technical problem uses, its
In, concrete technical scheme is：
Including rotor core, n pole is set in the rotor core, there are three blocks of magnet steel per pole, V words are arranged as per pole magnet steel
Type combines with yi word pattern, and yi word pattern is 1 piece of magnet steel C, is radial magnetic field, and V-shape is 2 pieces of magnet steel D, is tangential magnetic field, and adjacent two
The N and S of magnet steel are extremely corresponded to towards conversely.
A kind of above-mentioned mixed type permanent-magnet pole rotor, wherein：The magnet steel C, magnet steel D both sides set magnet isolation tank.
A kind of above-mentioned mixed type permanent-magnet pole rotor, wherein：Lightening grooves are set between pole and the V-shape magnet steel of pole.
A kind of above-mentioned mixed type permanent-magnet pole rotor, wherein：The magnet steel C, magnet steel D lower section set magnet steel groove.
A kind of above-mentioned mixed type permanent-magnet pole rotor, wherein：N be 4,6,8....., as sequence.
A kind of above-mentioned mixed type permanent-magnet pole rotor, wherein：The motor installs any one as described in claim 1-5
Mixed type permanent-magnet pole rotor.
The present invention has the advantages that relative to prior art：
1) compared with the motor of the radial direction magnetic field magnetic steel rotor structure such as " one " type, " V " type, " W " type, in terms of torque output
Unit volume magnet steel maximizes the use；
2) compared with the motor of " 1 " type or other forms tangential magnetic field magnetic steel rotor structure, in high speed weak magnetic and high temperature
Situation lower magnetic steel is not easy to demagnetize；
3) and because the lightening grooves of certain size shape design so that rotor weight mitigates, and motor torque density gets a promotion.

Footpath
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
In order to be more clearly understood that the technology contents of the present invention, described in detail especially exemplified by following examples.
Such as accompanying drawing 1：The present invention provides a kind of mixed type permanent-magnet pole rotor structure, per the arrangement of pole magnet steel shaped like yi word pattern and V
Font combines, and " one " is 1 block of magnet steel, is radial magnetic field, and " V " is 2 blocks of magnet steel, is tangential magnetic field.Two neighboring pole corresponds to the N of magnet steel
With S towards conversely.Between pole and " V " of pole, in the lightening grooves 6 of appropriate Position Design certain size shape.
This kind of rotor structure can make 4 poles, 6 poles, 8 poles ..., for 4 pole rotor structures, be designed with rotor core 2
12 magnet steel grooves, 24 magnet isolation tanks, four lightening grooves, by 12 blocks of magnet steel by class by corresponding to being regularly inserted into 12
In individual magnet steel groove, such as accompanying drawing 1；
There are three blocks of magnet steel per pole, be in yi word pattern and V-shape per three blocks of pole magnet steel, this three pieces of magnet steel one are a kind of size,
Another two be another size, such as accompanying drawing 1；, N, S pole after every block of magnet steel insertion magnet steel groove are towards by certain rule, two neighboring pole
N, S pole direction of corresponding magnet steel are opposite, such as accompanying drawing 1；See on magnet steel, magnet steel groove, magnet isolation tank 7, the related constraint size of lightening grooves 6
Accompanying drawing 2, accompanying drawing 3.
By accompanying drawing 2 and accompanying drawing 3 it can be seen that d armature axis reacts magnetic flux path and q armature axis reacts magnetic flux path, formed
" V " the type magnet steel of bidirectional magnetic field reacts magnetic flux path due to easily being demagnetized in the case of high speed weak magnetic and high temperature in d armature axis
" one " type magnet steel of radial magnetic field is set up, to increase d axle inductances.
It is also assumed that:Formed unidirectional magnetic field " one " type magnet steel due in terms of torque output unit volume magnet steel obtain not
Utilized to maximum, therefore " V " type magnet steel of tangential magnetic field is set up in d armature axis reaction magnetic flux path, to increase d axle magnetic resistance, to increase
The ratio of big q axle inductances and d axle inductances, so that moment of torsion obtains maximum lift.And certain size shape is designed between pole and pole
Lightening grooves to mitigate rotor weight.
Thus obtain：Compared with the motor of the radial direction magnetic field magnetic steel rotor structure such as " one " type, " V " type, " W " type, in moment of torsion
Output facet unit volume magnet steel maximizes the use, with " 1 " type or the motor of other forms tangential magnetic field magnetic steel rotor structure
Compare, magnet steel is not easy to demagnetize in the case of high speed weak magnetic and high temperature, and because being additionally arranged lightening grooves, motor torque density also obtains
Lifting.
