Description
Technical field
It the utility model is related to a kind of high-power and high-speed synchronous motor pole lamination.
Background technology
The general magnetic pole heavier-weight of high-power and high-speed synchronous motor, length is longer, acts on the centrifugation on pole core
Power and electromagnetic force are bigger.When rotor rotates, the centrifugal force that pole coil produces can be decomposed into two mutually perpendicular component,
Wherein the cross component force of centrifugal force can make pole coil produce injurious deformation along lateral, therefore need plus laterally secure between coil, need
With multiple tracks bracer structure, and such a structure seriously affects wind path, is unfavorable for the ventilating and cooling of motor.High-power and high-speed is same at present
The magnetic pole for walking motor uses the fixed structure of T tails more, but stress is higher at T tail fillets.
The content of the invention：
The purpose of the utility model is to provide it is a kind of it is rational in infrastructure, simple, be conducive to motor ventilation cooling and improve T tails
The high-power and high-speed synchronous motor pole lamination of stress state at fillet.The technical solution of the utility model is：A kind of big work(
The high synchronization motor pole punching of rate, synchronous motor pole lamination are salient-pole structure, there is a prominent magnetic pole, non-uniform air-gap,
Pole-core width is unequal, and the two sides of pole body are intended to electrical axis, its body includes pole shoe 1, pole body 2 and abnormity T tails
3, pole shoe 1 is equipped with damping hole 4, and pole body 2 is equipped with the different tie rod hole of two kinds of diameters:First pole core tie rod hole 5 and oblique angle
The second opposite pole core tie rod hole 6, pole body part are equipped with lamination index aperture 8, and the first pole core tie rod hole has in 5 hole
Half blacking and oblique angle is opposite, pole shoe 1 and abnormity T tails 3 are equipped with half slot 7, and pole body 2 is equipped with index aperture 8, at special-shaped T tails 3
Equipped with fillet 9.
3 neck of T tails is shape wide at the top and narrow at the bottom.
The operation principle and its advantage of the utility model：
Pole lamination is salient-pole structure, and pole-core width is unequal, and the two sides of pole body are centripetal, with radial inflow pole line
Circle coordinates so that the centrifugal force of pole coil does not produce cross component force, so as to cancel the structure that laterallys secure of coil, i.e., multiple tracks supports
Block structure, is conducive to the ventilating and cooling of motor；" special-shaped T tails " in the case where ensureing T tail neck intensity, by the shape of T tail necks
Shape is changed to shape wide at the top and narrow at the bottom, while increases T tails neck and the fillet on head, effectively reduces stress concentration, improves T tails
Stress state at neck and the fillet on head.In addition, the pole core tie rod hole that two kinds of diameters of pole body part are different, small straight
The pole core pull rod in footpath hole can play the role of positioning, so as to effectively improve the quality of pole core dress pressure；Pole shoe portion
The damping hole divided, amortisseur bar and damping hole are clearance fit, after amortisseur bar squeezes into pole core and is welded with damping ring, with spy
Punching iron core is broken into pit or by amortisseur bar swelling by different instrument, to prevent amortisseur bar vibration vertically；Pole shoe and T portions
Half slot, after pole core dress pressure, along iron core axial direction length direction full weld, the globality of pole lamination can be improved；Pole
The index aperture of body part, the positive and negative of punching is distinguished during for lamination.The advantages of the utility model：The ventilation for being conducive to motor is cold
But；Improve the stress state of pole lamination；Improve the dress pressure quality and globality of pole core；It is rational in infrastructure, simple, easily
In lamination.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
As shown in Figure 1, a kind of high-power and high-speed synchronous motor pole lamination, synchronous motor pole lamination is salient pole knot
Structure, there is prominent magnetic pole, and non-uniform air-gap, pole-core width is unequal, and the two sides of pole body are intended to electrical axis, its
Body includes pole shoe 1, pole body 2 and abnormity T tails 3, and pole shoe 1 is equipped with damping hole 4, and pole body 2 is equipped with the different tie rod hole of two kinds of diameters:
First pole core tie rod hole 5, the second pole core tie rod hole 6 opposite with oblique angle, pole body part are equipped with lamination index aperture 8,
There is half blacking in first pole core tie rod hole, 5 hole and oblique angle is opposite, pole shoe 1 is equipped with half slot 7, pole body 2 with abnormity T tails 3
Index aperture 8 is equipped with, fillet 9 is equipped with special-shaped T tails 3.
3 neck of T tails is shape wide at the top and narrow at the bottom.
Can be real by the second pole core tie rod hole 6 opposite with oblique angle of the first pole core tie rod hole 5 on body
Now a body is overlapped mutually, builds up pole core, pole core and pole end-plate dress are forced together with pole core pull rod,
After dress pressure, 7 full weld of half slot, amortisseur bar are welded together with damping ring again by damping hole 4 along iron core axial direction length direction,
Then pole coil is inserted in pole core and forms pole assemblage, and pass through special-shaped the T stern notches and key on special-shaped T tails 3 and yoke
Magnetic pole is fixed in yoke.Index aperture 8 on body, the positive and negative of punching is distinguished during available for lamination.
