Description
Technical field
The present invention relates to electrical generator fields, and in particular to a kind of rare-earth generator.
Background technique
Generator is the equipment for converting mechanical energy to 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 service life is low, electric control and protection poor reliability.
Summary of the invention
Goal of the invention: the present invention is directed to overcome the deficiencies of existing technologies, a kind of rare-earth generator is provided.
Technical solution: a kind of rare-earth generator, including casing, stator and rotor, the stator include by silicon steel sheet stack at
Stator core and the armature winding that is arranged on stator core, the rotor includes sheath, permanent magnetism Rare-Earth Magnetic steel disc, armature spindle
And magnetic yoke, the permanent magnetism Rare-Earth Magnetic steel disc are arranged on the outside of armature spindle, the shield is set 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 placing the magnetic yoke in the armature spindle
Portion.
Further, the hole portion is the blind hole that section is square, and the magnetic yoke is arranged in the hole portion.
Further, the permanent magnetism Rare-Earth Magnetic steel disc has 4, is arc-shaped flaky, 4 permanent magnetism Rare-Earth Magnetic steel disc settings
On the outside of the armature spindle.
Further, the permanent magnetism Rare-Earth Magnetic steel disc is bonded on the armature spindle.
Further, the magnetic yoke is made of rare earth permanent-magnetic material.
Further, the sheath is made of steel alloy.
Further, the stator is fixed on the housing.
The utility model has the advantages that 1. present invention are to substitute brushed DC electricity generation system with permanent-magnet brushless DC power generation system, do not have
Brush and commutator wear problem, life and reliability greatly improve, while maintenance rate is greatly reduced；
2. the present invention is made of rare earth permanent-magnetic material, magnet steel is low in energy consumption, conversion ratio is high, and small in size, light-weight, knot
Structure is simple, overload capacity is strong, high-efficient, motor smooth running, and being suitble to the micro- spray of high speed is the application of the unmanned plane of power；
3. armature spindle of the invention is directly connected with engine shaft, it is sluggish that this avoid transmissions；
4. AC/DC converting means of the invention, conveniently adjusted output voltage, applicability are wide.
Detailed description of the invention
Fig. 1 is generator side schematic view；
Fig. 2 is generator cross-sectional view.
Specific embodiment
Appended drawing reference: 1 stator；2 rotors；3 permanent magnetism Rare-Earth Magnetic steel discs；4 sheaths；5 magnetic yokes.
A kind of rare-earth generator, including casing, stator 1 and rotor 2, the stator include by silicon steel sheet stack at stator iron
Core and the armature winding being arranged on stator core, the rotor includes sheath 4, permanent magnetism Rare-Earth Magnetic steel disc 3, armature spindle and magnetic yoke
5, the permanent magnetism Rare-Earth Magnetic steel disc is arranged on the outside of armature spindle, and the shield is set 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 placing the magnetic yoke in the armature spindle.
The hole portion is the blind hole that section is square, and the magnetic yoke is arranged in the hole portion.The permanent magnetism Rare-Earth Magnetic steel disc has 4
It is a, 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 bonding
On the armature spindle.The magnetic yoke is made of rare earth permanent-magnetic material.The sheath is made of high-speed alloy steel.
The course of work: armature spindle connects engine shaft directly or by shaft coupling, and the present invention is turned by driven by engine
The magnetic flux of sub- axis rotation, the rotation of permanent magnetism Rare-Earth Magnetic steel disc and stator armature winding inter-turn on armature spindle changes,
Induced electromotive force is generated in armature winding, induced electromotive force turns linear ac signal through AC/DC power conversion unit
It changes stable DC into, is used for airborne equipment.
Although the present invention is illustrated and has been described with regard to preferred embodiment, it is understood by those skilled in the art that
Without departing from scope defined by the claims of the present invention, variations and modifications can be carried out to the present invention.
