Epoxy demarcation strip and the height for having the first epoxy demarcation strip are more than the depth of locating slot, and the outside diameter wall of the rotor core is circumferentially
Direction is fixed with multiple second epoxy demarcation strips and the second epoxy demarcation strip is between two adjacent the first epoxy demarcation strips,
Magnet steel is equipped between the first epoxy demarcation strip and the second epoxy demarcation strip and magnet steel is fixed in the outside diameter wall of rotor core.
As further improved technical scheme of the present invention, the first epoxy demarcation strip is pasted onto locating slot by glue
Interior, the magnet steel is pasted onto in the outside diameter wall of rotor core by glue, and the second epoxy demarcation strip is pasted onto by glue
In the outside diameter wall of rotor core.
As further improved technical scheme of the present invention, the first epoxy demarcation strip and the second epoxy demarcation strip are adopted
With FR4 epoxy materials, the rotor core uses irony bar, and the magnet steel is made of neodymium iron boron, the upper surface of the magnet steel
With the arc-shaped structure in lower surface, one end of the magnet steel is contacted with the first epoxy demarcation strip and the other end and the second epoxy separate
Plate contacts.
Beneficial effects of the present invention are：The the first epoxy demarcation strip and the second epoxy demarcation strip of the present invention is by FR4 epoxies
Plate is made, and the first epoxy demarcation strip is placed in the locating slot of rotor core, and is pasted with High-strength glue, plays positioning, branch
The effect of magnet steel is supportted, can accomplish that magnet steel is uniformly distributed, separately since magnet steel is spaced apart, while motor performance is not influenced,
The utilization of magnetic steel material is reduced, reduces cost, also mitigates the weight of motor in itself.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
