Reference Fig. 2, a kind of axial flux permanent magnet synchronous motor based on Halbach magnet ring and molded package winding, including
Runner assembly 100, fixation kit 200 and shell 300, runner assembly 100 include the first rotating member 101,102 and of the second rotating member
Third rotating member 103, the first rotating member 101 is identical with 102 structure and size of the second rotating member, the first rotating member 101 with
Second rotating member 102 is fixed on third rotating member 103, and the first rotating member 101 and the second rotating member 102 are symmetrical set；
Fixation kit 200 includes fixing piece 201 and winding 202, and winding 202 is set on 201 two sides of fixing piece, third rotating member 103
Across fixing piece 201, the first rotating member 101 and the second rotating member 102 are located at 201 two sides of fixing piece；Shell 300 is by first
Rotating member 101, the second rotating member 102 and fixing piece 201 are disposed within, and third rotating member 103 passes through shell 300.
Specifically, the first rotating member 101 includes first shaft hole 101a, magnet ring 101b and back iron 101c, first shaft hole 101a
Among back iron 101c, magnet ring 101b fits with back iron 101c, and the internal diameter of magnet ring 101b is greater than the aperture first shaft hole 101a,
The outer diameter of magnet ring 101b is less than the outer diameter of back iron 101c.
It should be noted that connection installation when, the side magnet ring 101b of the first rotating member 101 and the second rotating member 102 with
Winding 202 is staggered relatively, and the pore size of first shaft hole 101a is suitable with the diameter of third rotating member 103, the first rotating member 101
It is fixed with the second rotating member 102 by first shaft hole 101a and third rotating member 103, the first rotating member 101 and the second rotating member

101 and second there are gaps between rotating member 102 and shell 300, prevent the first rotating member 101 and the second rotating member 102 from rotating
When and shell 300 between generate friction, gap width about 1mm.
Halbach array is a kind of magnet structure, is the approximation of engineering coideal structure, and target is with minimal amount of magnet
Strongest magnetic field is generated, the arrangement of special magnet unit is utilized, enhances the field strength on unit direction, for having pole in engineering
For significance.Relative to conventional permanent magnet motor framework, parallel magnetic field and radial magnetic field after being decomposed due to Halbach magnet ring
Mutual superposition promotes the magnetic field strength of the other side significantly, can effectively reduce the volume of motor in this way, promote motor
Power density；In conventional permanent magnet motor, since air-gap field inevitably has harmonic wave, generally adopted on rotor framework
Skewed slot is taken to weaken its influence.In Halbach motor, since air-gap field Sine distribution degree is higher, harmonic content is small, therefore fixed
Rotor is not necessarily to skewed slot；Because the unilateral Distribution of Magnetic Field that Halbach magnet self-shielding effect generates no longer needs rotor using magnetic
Material provides access for it, so be only rotor material selection provide biggish selection space, and can make system have compared with
Low rotary inertia and the performance that preferably quickly echos；Using Halbach magnet array, the torque ripples of motor can be reduced
Wave, thus the bearing requirements of motor are greatly reduced.
The Halbach magnet structure of traditional piece is assembled using multiple magnets of the different direction of magnetizations, different magnets
Between existing repulsive force cause assembled difficulty big, at high cost, precision is not high, and the fixation difficulty of assembled magnet is big, structure
Stiffness and strength are poor.In the present embodiment, the first rotating member 101 and the second rotating member 102 are rotor using Halbach magnet ring and back
Iron 101c structure, magnet ring 101b use the Halbach magnet ring of one-pass molding sintering, and assembly difficulty is small, the rigidity of structure and intensity are good,
Magnetic property is stablized.Back iron 101c, which is used, uses electrical pure iron, and magnetic conductivity is good, and lower compared to silicon steel sheet cost, the rigidity of structure is more preferable.
Magnet ring 101b forms enhancing magnetic field in one end close to winding 202, improves the air gap flux density of motor, improves the power density of motor
With the reliability of motor work.On the whole, the poly- magnetic effect of Halbach magnet ring, the magnetic conductivity of back iron 101c and the first rotating member
101 and second gap between rotating member 102 and shell 300 magnetoresistance, reduce the brow leakage of motor.
Embodiment 3

The aperture of second axis hole 201a be greater than first shaft hole 101a aperture 101a, and first shaft hole 101a aperture 101a with
The diameter of third rotating member 103 is suitable, therefore the aperture of the second axis hole 201a is greater than the diameter of third rotating member 103, in this way, third
The rotation of rotating member 103, which does not contact, nor affects on fixing piece 201.Groove 201b is closure, shape approximate trapezoid, winding
202 shape and groove 201b shape identical match, can be placed in just in groove 201b.Raised 201c shape approximation cuboid,
Wherein one side is connected with the edge of fixing piece 201, communicates inside raised 201c inner hollow and junction and fixing piece 201,
For placing driving circuit in accommodating space, worked with driving motor.Meanwhile driving circuit envelope integrated with fixing piece 201
Dress improves the space utilization rate of motor and the rigidity of structure, reduces motor volume, is conducive to the reduction and performance of motor cost

Be by liquid-state epoxy resin compound with mechanical or manual mode fill people equipped with electronic component, route device in, in room temperature or
The thermosetting polymer insulating materials haveing excellent performance is solidified under heating condition.Primary concern is dosing technology, and encapsulating produces
The quality of product is mainly closely related with product structure design, element selection, assembling and Embedding Material used, and dosing technology is also not
Hold the factor ignored.Epoxy resin encapsulated has 2 kinds of dosing technologies of normality and vacuum, in which: epoxy resin, amine normal temperature cure fill
Envelope material is generally used for low-voltage electrical apparatus, mostly uses normality encapsulating；Epoxy resin, acid anhydrides are heating and curing potting compound, are generally used for high pressure
Electronic device encapsulating mostly uses vacuum encapsulation technology, uses vacuum encapsulation technology here.Winding 202 solidifies work through epoxy sealing
After skill, wiring is neat, makes full use of axially and radially space in design, and design margin is big, and iron-free cored structure torque pulsation is low,
The poly- magnetic effect of Halbach magnet ring compensates for the deficiency of iron-free cored structure, and the cure package of form-wound coils 202 improves motor
