Description
Technical field
It the utility model is related to electrical generator fields, and in particular to a kind of rare-earth generator.
Background technology
Generator is the equipment that mechanical energy is converted into electric energy, and unmanned plane uses brushed DC electricity generation system at present；There is brush
The shortcomings that DC power generation system, has：The abrasion of brush and commutator is big, the life-span is low, electric control and protection poor reliability.
Utility model content
Purpose of utility model：A kind of the defects of the utility model is intended to overcome prior art, there is provided rare-earth generator.
Technical scheme：A kind of rare-earth generator, including casing, stator and rotor, the stator include by silicon steel sheet stack into
Stator core and the armature winding that is arranged on stator core, the rotor include sheath, permanent magnetism Rare-Earth Magnetic steel disc, armature spindle
And yoke, the permanent magnetism Rare-Earth Magnetic steel disc are arranged on the outside of armature spindle, the sheath is arranged on outside the armature spindle, the permanent magnetism
Rare-Earth Magnetic steel disc is crushed between the armature spindle and the sheath, has the hole for being used for placing the yoke in the armature spindle
Portion.
Further, the hole portion is the blind hole that section is square, and the yoke is arranged in the hole portion.
Further, the permanent magnetism Rare-Earth Magnetic steel disc has 4, is arc-shaped flaky, and 4 permanent magnetism Rare-Earth Magnetic steel discs are set
On the outside of the armature spindle.
Further, the permanent magnetism Rare-Earth Magnetic steel disc is bonded on the armature spindle.
Further, the yoke is made up of rare earth permanent-magnetic material.
Further, the sheath is made up of steel alloy.
Further, the stator is fixed on the housing.
Beneficial effect：1. the utility model is to substitute brushed DC electricity generation system with permanent-magnet brushless DC power generation system,
There is no brush and commutator wear problem, life and reliability is greatly improved, while maintenance rate is greatly reduced；
2. the utility model is made of rare earth permanent-magnetic material, magnet steel is low in energy consumption, conversion ratio is high, and small volume, weight
Gently, simple in construction, overload capacity is strong, efficiency high, motor smooth running, is adapted to applied field of the micro- spray of high speed for the unmanned plane of power
Close；
3. armature spindle of the present utility model is directly connected with engine shaft, sluggish this avoid transmission；
4. AC/DC converting means of the present utility model, conveniently adjusted output voltage, applicability are wide.
Brief description of the drawings

Fig. 2 is generator cross-sectional view.
Embodiment
Reference：1 stator；2 rotors；3 permanent magnetism Rare-Earth Magnetic steel discs；4 sheaths；5 yokes.
A kind of rare-earth generator, including casing, stator 1 and rotor 2, the stator include by silicon steel sheet stack into stator iron
Core and the armature winding being arranged on stator core, the rotor include sheath 4, permanent magnetism Rare-Earth Magnetic steel disc 3, armature spindle and yoke
5, the permanent magnetism Rare-Earth Magnetic steel disc is arranged on the outside of armature spindle, and the sheath is arranged on outside the armature spindle, the permanent magnetism rare earth
Magnetic links are crushed between the armature spindle and the sheath, have the hole portion for being used for placing the yoke in the armature spindle.
The hole portion is the blind hole that section is square, and the yoke is arranged in the hole portion.The permanent magnetism Rare-Earth Magnetic steel disc has 4
It is individual, it is arc-shaped flaky, 4 permanent magnetism Rare-Earth Magnetic steel discs are arranged on the outside of the armature spindle.The permanent magnetism Rare-Earth Magnetic steel disc bonds
On the armature spindle.The yoke is made up of rare earth permanent-magnetic material.The sheath is made up of high-speed alloy steel.
The course of work：Armature spindle connects engine shaft directly or by shaft coupling, and the utility model passes through engine band
The sub- axis rotation of turn, the magnetic flux of the rotation of permanent magnetism Rare-Earth Magnetic steel disc and stator armature winding inter-turn on armature spindle become
Change, induced electromotive force is produced in armature winding, induced electromotive force will linearly exchange telecommunications through AC/DC power conversion unit
Number galvanic current is converted into, is used for airborne equipment.
Although the utility model is illustrated and described with regard to preferred embodiment, those skilled in the art should manage
Solution, without departing from claim limited range of the present utility model, the utility model can be carried out various change and
Modification.
