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 the motor.Pole core generally is riveted with sheet pack and forms, the columnar part of pole core is called the magnetic pole pole body, be welded with the pole shoe that is built up by the pole shoe punching on the magnetic pole pole body, existing pole shoe lamination structure as shown in Figure 8, the pole shoe punching dual-side and on flat limit be designed with welding groove, after the pole shoe punching stacks in welding groove welding form pole shoe.In Electromagnetic Design, for weakening tooth-harmonic emf, when being fixed on the magnetic pole pole body, wants by pole shoe relative pole core axis inclination certain angle δ (angle δ determines according to the concrete relevant parameter of motor), the structure that pole shoe tilts as shown in Figure 6, be that pole shoe builds up herringbone by the pole shoe punching, the angle of the hypotenuse of herringbone pole shoe and its horizontal axis of face, place is δ; When making pole core, utilize first frock that some pole shoe punchings are built up as shown in Figure 6 shape, weld in the welding groove position again, the pole shoe punching is welded as a whole, form pole shoe, pole shoe and magnetic pole pole body fix with tool locating, and be then welded in magnetic pole pole body bevel for welding position, forms pole core.The pole core structure of this kind herringbone pole shoe has caused pole shoe to laminate difficulty, needs the special tooling location, clamps, and production efficiency is low, and the pole core manufacturing cost is high.Welding capacity is large in the manufacturing process, the easy torsional deformation of pole shoe in welding process; With the pole core of this structure when the coiling pole coil, for guaranteeing its insulation property, need to overlap insulating pad at the magnetic pole pole body, and the insulating pad on the magnetic pole pole body front-back can fill up on pole shoe, and the insulating pad on the magnetic pole pole body two sides does not have the structure that can support, again because the poor rigidity of insulating pad own, when the coiling pole coil, the insulating pad of magnetic pole pole body two sides is yielding, causes the pole coil extruding that misplaces when coiling, and the pole coil cracky is scrapped.
Summary of the invention
The present invention causes pole shoe to laminate that difficulty, manufacturing cost are high, efficient is low, yielding in order to solve existing pole core structure, and the pole coil cracky problem, a kind of pole core is provided.
The present invention adopts following technical scheme to realize: pole core, comprise the magnetic pole pole body, be welded with the pole shoe that is built up by the pole shoe punching on the magnetic pole pole body, be extended with the location lug on pole shoe punching and the limit that the magnetic pole pole body contacts, be provided with along its length lambdoid gathering sill on the contact-making surface of magnetic pole pole body and pole shoe, the angle of the hypotenuse on the gathering sill and its horizontal axis of face, place is δ, this angle δ is the angle δ that wants relative pole core axis to tilt for weakening the tooth-harmonic emf pole shoe on being fixed on the magnetic pole pole body time in the Electromagnetic Design, gathering sill and described location lug matched in clearance.The trend of the gathering sill of pole shoe punching on the magnetic pole pole body stacks piecewise, so that laminating of pole shoe is simple to operate, production efficiency improves, do not need simultaneously special-purpose tool locating yet, reduced the cost of manufacture of pole core, welding capacity reduces in the pole core manufacturing process, and pole shoe is not yielding in welding process yet.
Above-mentioned pole core, pole shoe punching two ends have laminated the pole shoe baffle plate, and the profile of pole shoe baffle plate is identical with described pole shoe punching; The pole shoe baffle plate can prevent that pole shoe from laminating rear appearance fan and rising, thereby has guaranteed the stacking factor of pole shoe, and pole shoe baffle plate profile is identical with the pole shoe punching, makes things convenient for the fixing of pole shoe baffle plate, also can not affect the magnetic circuit of magnetic pole iron.
Above-mentioned pole core, also comprise the magnetic pole baffle plate, the magnetic pole baffle plate is made of the transverse slat that the riser that has welding hole and horizontal vertical are fixed on the riser lower end, the magnetic pole baffle plate is welded on by the welding hole on it on two sides of magnetic pole pole body, and a plate face of the riser of magnetic pole baffle plate is attached on the side of magnetic pole pole body fully.The transverse slat of magnetic pole baffle plate has supporting role to the insulating pad of magnetic pole pole body two sides when the coiling pole coil, so that insulating pad is not yielding when the coiling pole coil, it is regular to guarantee that pole coil twines, and pole coil is not fragile.
Above-mentioned pole core, the two ends downward bending of described transverse slat, then the transverse slat on the magnetic pole baffle plate becomes the U-shaped plate, and the U-shaped plate can better prevent the insulating pad distortion of magnetic pole pole body two sides than straight plate good rigidly.
The present invention compares with existing pole core, has significant progress:
1. simplified special tooling structure and pole shoe and laminated operation, reduced frock quantity, according to statistics, the frock expense has descended 70%, has reduced the manufacturing cost of pole core;
2. reduce welding capacity, solved pole shoe welding torsional deformation problem, improved product quality, improved motor performance;
3. the short problem of coil cracky circle has promoted product quality when having solved the coiling pole coil;
4. enhance productivity, reduce the waster rate, according to statistics, the waster rate has reduced by 90%.
