Description
Technical field
The present invention relates to the magnetic induction parts of motor, be specially a kind of pole core.
Background technology
Pole core is building block important in motor.Pole core is generally riveted with sheet pack and forms, the columnar part of pole core is called magnetic pole pole body, magnetic pole pole body is welded with the pole shoe built up by pole shoe punching, existing pole shoe lamination structure as shown in Figure 8, pole shoe punching dual-side and on flat limit is designed with welding groove, after pole shoe punching stacks, in welding groove, welding forms pole shoe.In Electromagnetic Design, for weakening tooth-harmonic emf, opposing polarities axis inclination certain angle δ (angle δ determines according to the concrete relevant parameter of motor) unshakable in one's determination is wanted when pole shoe is fixed on magnetic pole pole body, the structure that pole shoe tilts as shown in Figure 6, namely pole shoe builds up herringbone by pole shoe punching, and the angle of the horizontal axis of the hypotenuse of herringbone pole shoe and its face, place is δ; When making pole core, first utilize frock that some pole shoe punchings are built up shape as shown in Figure 6, again in the welding of welding groove position, pole shoe punching is welded as a whole, form pole shoe, pole shoe and magnetic pole pole body tool locating fix, then welded in magnetic pole pole body bevel for welding position, form pole core.The pole core structure of this kind of herringbone pole shoe, causes pole shoe and laminates difficulty, and need special tooling to locate, clamp, production efficiency is low, and pole core manufacturing cost is high.In manufacturing process, welding capacity is large, the easy torsional deformation of pole shoe in welding process; With the pole core of this structure when coiling pole coil, for ensureing its insulation property, insulating pad need be overlapped on magnetic pole pole body, and the insulating pad on magnetic pole pole body front-back can pad on pole shoe, the insulating pad on magnetic pole pole body two sides does not have the structure that can support, again due to the poor rigidity of insulating pad own, when coiling pole coil, the insulating pad of magnetic pole pole body two sides is yielding, and cause pole coil to misplace when coiling extruding, pole coil cracky is scrapped.
Summary of the invention
In order to solve existing pole core structure, the present invention becomes that pole shoe laminates difficulty, manufacturing cost is high, efficiency is low, yielding, and pole coil cracky problem, provide a kind of pole core.
The present invention adopts following technical scheme to realize: pole core, comprise magnetic pole pole body, magnetic pole pole body is welded with the pole shoe built up by pole shoe punching, the limit that pole shoe punching contacts with magnetic pole pole body is extended with location lug, the contact-making surface of magnetic pole pole body and pole shoe is provided with lambdoid gathering sill along its length, the angle of the horizontal axis of the hypotenuse on gathering sill and its face, place is δ, this angle δ is for weakening tooth-harmonic emf pole shoe wants opposing polarities axis unshakable in one's determination to tilt angle δ when being fixed on magnetic pole pole body in Electromagnetic Design, gathering sill and described location lug matched in clearance.Pole shoe punching stacks piecewise along the trend of the gathering sill on magnetic pole pole body, make laminating of pole shoe simple to operate, production efficiency improves, do not need special tool locating simultaneously yet, reduce the cost of manufacture of pole core, in pole core manufacturing process, welding capacity reduces, and pole shoe is not yielding in welding process yet.
Above-mentioned pole core, pole shoe punching two ends have laminated pole shoe baffle plate, and the profile of pole shoe baffle plate is identical with described pole shoe punching; Pole shoe baffle plate can prevent from pole shoe from laminating rear appearance fan rising, thus ensure that the stacking factor of pole shoe, and pole shoe baffle plate profile is identical with pole shoe punching, facilitates the fixing of pole shoe baffle plate, also can not affect the magnetic circuit of magnetic pole iron.
Above-mentioned pole core, also comprise magnetic pole baffle plate, the transverse slat that magnetic pole baffle plate is fixed on riser lower end by the riser and horizontal vertical that have welding hole is formed, magnetic pole baffle plate is welded on the two sides of magnetic pole pole body by the welding hole on it, and a plate face of the riser of magnetic pole baffle plate is attached on the side of magnetic pole pole body completely.The transverse slat of magnetic pole baffle plate, when coiling pole coil, has supporting role to the insulating pad of magnetic pole pole body two sides, makes insulating pad not yielding when coiling pole coil, and ensure that pole coil is wound around regular, pole coil is not fragile.
Above-mentioned pole core, the two ends downward bending of described transverse slat, then the transverse slat on magnetic pole baffle plate becomes U-board, and U-board, than straight plate good rigidly, can better prevent the insulating pad of magnetic pole pole body two sides to be out of shape.
The present invention compares with existing pole core, has significant progress:
1. simplify special tooling structure and pole shoe laminates operation, reduce frock quantity, according to statistics, frock expense have dropped 70%, reduces the manufacturing cost of pole core;
2. decrease welding capacity, solve pole shoe welding torsional deformation problem, improve product quality, improve motor performance;
3. when solving coiling pole coil, the short problem of coil cracky circle, improves product quality;
4. enhance productivity, reduce waster rate, according to statistics, waster rate reduces 90%.
