Abstract
The utility model provides a 16 pole permanent magnet motor integral rotor punching sheet which comprises a shaft hole, magnetic steel grooves, magnetic shield cavities, bars and a sheet body. The sheet body is circular. The sheet body is provided with the shaft hole. The magnetic steel grooves are evenly distributed around the circumference of the shaft hole in a discontinuous circle. The magnetic steel grooves and the magnetic shield cavities are vertically connected. The magnetic shield cavities are filled with air. The bars are distributed in gaps between the magnetic shield cavities. According to the utility model, the 16 pole permanent magnet motor integral rotor punching sheet is simple in structure, and uses the air magnetic shield cavities; secondary magnetic steel is saved; the production cost is reduced; the ladder-shaped punching sheet is changed to be arc-shaped; a knuckle is arranged in an acute corner; the stress of the corner is reduced, thus the fastness is improved; and the work efficiency is improved.
Description
Technical field
The utility model relates to magneto accessory field, the particularly rotor punching of magneto.
Background technology
In the prior art, the magnet steel groove of three-phase self-starting 16 pole permanent magnet motor rotor punchings divides main magnet steel groove and secondary magnet steel groove, main magnet steel groove and the secondary magnet steel groove T-shaped shape that is connected, and Rao Yuan center is uniformly distributed.But due to its complex structure, production cost is high, and inefficiency in the running, time-consuming.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, and a kind of 16 pole permanent magnet motor integral type rotor punchings are provided, and original secondary magnet steel groove is changed into every magnetic cavity, has greatly saved production cost, and has improved operating efficiency.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
16 pole permanent magnet motor integral type rotor punchings, comprise axis hole, magnet steel groove, every magnetic cavity, muscle and lamellar body, and described lamellar body is circular, on described lamellar body, has axis hole; Described magnet steel groove distributes along the even circumferential of axis hole, is the circle of interruption; Described magnet steel groove is all connected with every magnetic cavity is vertical; Described be air in magnetic cavity; Described muscle is distributed in the interval every magnetic cavity.
Further, the center of circle of described lamellar body and axis hole is the same center of circle.
Further, the quantity of described magnet steel groove is 16.
Further, the described quantity every magnetic cavity is 16, described curved every magnetic cavity.
Further, the described height h every magnetic cavity is 8mm～12mm, and the described turning every magnetic cavity is the fillet of radius 1mm～2mm.
A kind of 16 pole permanent magnet motor integral type rotor punchings of the utility model, the present invention is distributed along even circumferential by 16 magnet steel grooves, magnet steel groove lower end connect kidney-shaped every magnetic cavity, the muscle that leaves 2～3mm between groove and groove plays the effect that is connected circular center section and magnetic pole.In its magnet isolation tank, need not place magnet steel, with air directly every magnetic, saved the magnet steel consumption every magnetic, saved production cost, and the trapezoidal arc that become, the knuckle that radius is 1～2mm has all been made at acute angle place, has reduced the stress of corner, increase fastness, thereby improved operating efficiency.
