Steel material it is unrestrained the phenomenon that.Rare earth permanent-magnetic material is expensive, and motor cost is high.And it is difficult to accomplish that magnet steel is uniformly distributed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of separation magnet steel in view of the above shortcomings of the prior art
Rotor structure, the rotor structure of this separation magnet steel is on the basis of Alnico rotor structure is pasted on surface, the arrangement mode of magnet steel
It is changed to be alternatively arranged by close-packed arrays, reduces the utilization of magnetic steel material, alleviate the weight of motor, reduce cost.
To realize the above-mentioned technical purpose, the technical solution that the utility model is taken is:
A kind of rotor structure separating magnet steel, including rotor core, magnet steel, the first epoxy demarcation strip and the second epoxy separate
Plate, the outside diameter wall of the rotor core is uniformly spaced in the circumferential direction to be equipped with multiple locating slots, is fixed in the locating slot
First epoxy demarcation strip and the depth for thering is the height of the first epoxy demarcation strip to be more than locating slot, the outside diameter wall edge of the rotor core
Circumferencial direction is fixed with multiple second epoxy demarcation strips and the second epoxy demarcation strip is located at two adjacent the first epoxy demarcation strips
Between, it is equipped with magnet steel between the first epoxy demarcation strip and the second epoxy demarcation strip and magnet steel is fixed on the outer diameter of rotor core
On wall.
As the further improved technical solution of the utility model, it is fixed that the first epoxy demarcation strip is pasted onto by glue
In the slot of position, the magnet steel is pasted onto by glue in the outside diameter wall of rotor core, and the second epoxy demarcation strip is viscous by glue
It is attached in the outside diameter wall of rotor core.
As the further improved technical solution of the utility model, the first epoxy demarcation strip and the second epoxy demarcation strip
Be all made of FR4 epoxy materials, the rotor core uses irony bar, the magnet steel to be made of neodymium iron boron, the magnet steel it is upper
The arc-shaped structure in surface and lower surface, one end of the magnet steel is contacted with the first epoxy demarcation strip and the other end and the second epoxy
Demarcation strip contacts.
The beneficial effects of the utility model are:The first epoxy demarcation strip and the second epoxy demarcation strip of the utility model by
FR4 epoxy plates are made, and the first epoxy demarcation strip is placed in the locating slot of rotor core, is used in combination High-strength glue to paste, plays
Positioning, the effect of support magnet steel, can accomplish that magnet steel is uniformly distributed, separately since magnet steel is spaced apart, not influence motor performance
While, the utilization of magnetic steel material is reduced, cost is reduced, also mitigates the weight of motor itself.
