Abstract
The invention provides a 16-pole permanent magnet motor integrated rotor punching sheet comprising a shaft hole, magnetic steel slots, magnetic separation chambers, ribs and a sheet body. The sheet body is circular, and the sheet body is provided with the shaft hole. The magnetic steel slots are evenly distributed along the circumference of the shaft hole in an intermittent circle. The magnetic steel slots are perpendicularly connected with the magnetic separation chambers which are internally provided with air. The ribs are distributed at the intervals of the magnetic separation chambers. The 16-pole permanent magnet motor integrated rotor punching sheet is simple in structure, and the air magnetic separation chambers are adopted so that secondary magnetic steel is saved and production cost is reduced. Besides, the trapezoids are converted into arc shapes, and acute angel positions are converted into transition fillets so that stress of the corners can be reduced, firmness is increased and thus working efficiency is enhanced.
Description
Technical field
The present invention relates to magneto accessory field, particularly the 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 punching divides main magnet steel groove and secondary magnet steel groove, and main magnet steel groove is connected with secondary magnet steel groove T-shaped shape, is uniformly distributed around circle center.But due to its complex structure, production cost is high, and inefficiency in the running, time-consuming.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of 16 pole permanent magnet motor integral type rotor punchings, change into every magnetic cavity, greatly saved original secondary magnet steel groove production cost, and improve operating efficiency.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of 16 pole permanent magnet motor integral type rotor punchings, comprise axis hole, magnet steel groove, every magnetic cavity, muscle and lamellar body, described lamellar body are circular, and described lamellar body has axis hole; Described magnet steel groove distributes along the even circumferential of axis hole, in the circle of being interrupted; 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 present invention, the present invention is circumferentially uniformly distributed by 16 magnet steel grooves, magnet steel groove lower end connect kidney-shaped every magnetic cavity, the muscle leaving 2 ~ 3mm between groove with groove plays the effect being connected circular center section and magnetic pole.Magnet steel need not be placed in its magnet isolation tank, with air directly every magnetic, eliminate the magnet steel consumption every magnetic, save production cost, and become arc trapezoidal, the knuckle that radius is 1 ~ 2mm has all been made at acute angle place, decreases the stress of corner, add fastness, thus improve operating efficiency.
