Description
Technical field
The present invention relates to a kind of stator separate type Linear-rotation permanent-magnet actuators, for needing to realize straight line and rotation two certainly
By the occasion of degree compound motion.
Background technique
In industrial applicability, it is often necessary to which drive system realizes multivariant movement.Straight line and rotation two-freedom fortune
Flowing mode as various dimensions movement one of, be with a wide range of applications, can be employed for high-precision processing, robot,
The occasions such as electric car, magnetic artillery transmitting.The conventional implementation of straight line rotation two-freedom movement is that combination two is independent
Motor, still, this method transmission system are complicated, and volume is larger, and transmission efficiency is low.To overcome the rotation of conventional ASSEMBLE straight line to make
The shortcomings that dynamic system, existing part document propose the single actuator that straight line may be implemented and rotate the movement of two freedom degrees.
But existing actuator performance still has many performances to need to be further increased.
Summary of the invention
Technical problem: in order to overcome, existing straight line rotation two-freedom permanent magnetic actuator power density is small, reliability is low
The shortcomings that, the invention proposes a kind of stator separate type Linear-rotation permanent-magnet actuators, reduce interelectrode magnetic leakage, improve actuator gas
Gap Distribution of Magnetic Field improves power density, reduces armature field to the degaussing risk of permanent magnetism.
Technical solution: a kind of stator separate type straight line rotates two-freedom permanent magnetic actuator, including external stator, rotor, interior
Three parts of stator；
The external stator part subpackage is containing three axially aligned independent annular external stator units, each annular external stator
Unit includes annular external stator iron core and armature winding, is uniformly distributed circumferentially 6 stators on the inside of the annular external stator iron core
Tooth is wound with armature winding on each stator tooth；The stator tooth edge of three external stator units is axial coaxially arranged, so that external stator is electric
Pivot winding contains 1 electric period along axial；
The rotor portion generally sandwich cup-like structure by several rotor core blocks and connects rotor core block
Non-magnetic sheath is constituted；
The inner stator subpackage contains three axially aligned independent default subelements, and each default subelement is by ring
Shape internal stator iron core and it is set to the permanent magnet battle array being circumferentially interspersed with axial polarity on the outside of annular internal stator iron core
Column are constituted.
Further, each annular internal stator iron core is equipped with 24 pieces of permanent magnets, and two opposite polarity permanent magnets are axial
One group of formation, 12 groups of set of permanent magnets are merged into, 12 groups of set of permanent magnets are evenly arranged along internal stator iron core external circumferential, so that default
Circumferentially contain 6 pairs of poles on the outside of sub- permanent magnet；The set of permanent magnets of three default subelements forms permanent magnet array, every piece of permanent magnet
Circumferentially it is contrary with 4 pieces of axially adjacent permanent magnet polarities.
Further, the rotor core block is formed by silicon steel plate packing.
Further, the non-magnetic sheath is epoxy resin sheath or carbon fiber sheath.It is installed at outside mover and is used to mention
High mover intensity.
Further, the rotor portion includes 16 axially aligned rotor core rings, each rotor core ring packet
The axially staggered arrangement of rotor core block containing 8 rotor core blocks, between 16 rotor core rings.
The utility model has the advantages that stator separate type flux-reversal straight line rotary actuator permanent magnetic field is shorter by the path of rotor,
So that magnetic resistance is smaller, reduce leakage field, to greatly improve electromagnetic performance.In addition, in two directions of motion of straight line and rotation
On follow flux-reversal operation logic so that two sets of threephase armature windings of axial and circumferential can linkage obtain sinusoidal magnetic linkage
And back-emf, so that traditional alternating-current synchronous method of operation, speed regulating control algorithm can be used in the movement of two freedom degrees
It is relatively easy, there is actual engineering application value.
