Referring to Fig.1 and 2, a kind of high speed permanent magnet motor rotor 100 is present embodiments provided, including：
Rotor core 10；
Magnet steel 30, the quantity of magnet steel 30 is multiple, axis direction and circumferential direction point of multiple magnet steel 30 along rotor core 10
Section is arranged in the outer surface of rotor core 10；
Shielded layer 50, is wrapped in the outer surface of magnet steel 30 and is interference fitted with magnet steel 30；
Protective case outer layer 70, is wrapped in the outer surface of shielded layer 50；With
Sealing, for filling the pole clearance of magnet steel 30 and by the both ends of whole high speed permanent magnet motor rotor 100
Magnet steel 30 end face seal.
Wherein, magnet steel 30 is to adopt the outer surface for being arranged in rotor core 10 in the method for paste.
Wherein, the thickness of shielded layer 50 is 0.01-2mm.In view of the convenience of processing, the shielded layer 50 of the present embodiment
Thickness is preferably 2mm.
In the present embodiment, protective case outer layer 70 is alloy strip steel rolled stock, and protective case outer layer 70 is wrapped in screen in a manner of winding
Cover the outer surface of layer 50.
Shielded layer 50 can be it is copper can also be the metal materials such as aluminum.In the present embodiment, the material of shielded layer 50
Preferably copper product.
Detailed, sealing includes the first sealing 80 and the second sealing 81.First sealing 80 is filled in magnet steel 30
Pole clearance and cause multiple magnet steel 30 fix between each other, the second sealing 81 will be in whole high speed permanent magnet motor rotor
The end face seal of the magnet steel 30 at 100 both ends.
Further, the thickness of the second sealing 81 is 1-5mm.In order to better control over size, preferably 1mm, 2mm,
The size of integer as 3mm, 4mm and 5mm is used as the thickness during structure of the second sealing 81.
In order to realize the filling between magnet steel 30 and the end face seal of both ends magnet steel 30, the sealing of the present embodiment is by close
Sealing is formed, and the structure of the first sealing 80 and the second sealing 81 is completed by way of embedding.So that what is built is close
Envelope portion can stablize, and ensure that the overall structure of rotor is stablized.
The principle of the present embodiment is：
By the way that in the outer surface step-by-step arrangement of rotor core 10, magnet steel 30 axially and radially can all played suppression magnetic
The effect of the internal vortex of steel 30, meanwhile, the magnet steel 30 after segmentation is also avoided that causes stress concentration in 30 inner radius of magnet steel
Harmful effect.
Have the first sealing 80 for forming of fluid sealant filling between the pole clearance of magnet steel 30, can so prevent magnet steel 30 it
Between mutual play, so as to avoid magnet steel 30, collision causes the adverse consequences such as damage or loss of excitation each other, ensure it is whole at a high speed
The overall structure of permanent magnet machine rotor 100 is stablized.
Further, both ends magnet steel 30 end face embedding fluid sealant, formed 1-5mm thickness the second sealing 81.This
On the one hand sample can further prevent 30 play of magnet steel, play the role of axial restraint, improve between magnet steel 30 and rotor core 10
Connection stability, on the one hand magnet steel 30 can also be isolated from the outside, to avoid both ends magnet steel 30 in production process or
It is damaged in person's course of work.
Further, shielded layer 50 is copper product, when whole high speed permanent magnet motor rotor 100 works, is run at high speed
High speed permanent magnet motor rotor 100 produces vortex in copper shielded layer 50, and the demagnetizing effect being vortexed can be realized to magnet steel 30
Protection.
Copper shielded layer 50 also has the good capacity of heat transmission, can be tied when high speed permanent magnet motor rotor 100 works
Higher rotating speed is closed, rapidly conducts heat so that the overall temperature rise unobvious of high speed permanent magnet motor rotor 100.
Also, copper 50 overall structure of shielded layer is simultaneously uncomplicated, when manufacture, is also easier to volume production.Copper shielded layer 50
Quality it is also softer with respect to for magnet steel 30, by the way of interference fit, assembling it is quicker, also help and avoid producing
Magnet steel 30 is damaged during assembling, this is just more conducive to the raising of assembling speed, and the requirement of production is lower, and quality is more secure.
And in order to enable shielded layer 50 to play effectiveness, protection has been wound in using alloy strip steel rolled stock in 50 outer surface of shielded layer
Outer layer 70 is covered, in case the softer copper shielded layer 50 of quality damages.
Softer than magnet steel 30 in view of heat conductivility and quality itself, it is also what is be applicable in that aluminum, which makes shielded layer 50, its
The metal material of his similar characteristics is also that can increase the material choosing that shielded layer 50 produces as aluminum optionally
Select scope.
The high speed permanent magnet motor rotor 100 of the present embodiment, by arranging magnet steel 30 in 10 surface segment of rotor core, is adopted
With fluid sealant to build the first sealing 80 and the second sealing 81, and pacified on 30 surface of magnet steel by way of interference fit
Shielded layer 50 is filled, and selects making material of the copper product as shielded layer 50, is aided with alloy strip steel rolled stock to build the anti-of shielded layer 50
Shield.
So that the overall structure of high speed permanent magnet motor rotor 100 is stablized, eddy-current loss during work is small, suppresses in permanent magnet
Bilge vortex, reduces permanent magnet own loss, beneficial to the stress concentration for eliminating permanent magnet inner radius.Good heat-sinking capability also avoids
Temperature rise is excessive, improves the magnetic shield performance under high-speed permanent magnet motor high frequency, reduces the requirement for permanent magnet performance.It is very suitable
For magneto and further high-speed permanent magnet motor.
