Abstract

The utility model provides an iron core used for a generator or a motor. The iron core includes an iron core body form by laminating and riveting iron sheets into a whole, and insulation skeletons arranged on two sides of the iron core body. The two sides of the iron core are provided with two iron sheets having axial bending parts on outer edges. Outer side faces of the bending parts are exposed is the outer side faces of the bending parts are arc-shaped faces in alignment with tooth surfaces of corresponding positions of the other iron sheets. By using the iron core used for the generator or the motor in the utility model, the magnetic conduction area of the iron core is increased and the output power is improved under the same condition. Moreover, the mechanical strength of the magnetic conduction face of the iron core is high. and the iron core used for the generator or the motor in the utility model has a simple manufacturing technique and a low cost.

Description

The iron core that is used for generator or motor

Technical field

The utility model relates to generator or the used iron core of motor.

Background technology

Generator or motor iron-core are made up of the folded riveting of some moulding iron plates (punching), and the surface adopts technologies such as injection moulding, setting-in insulation framework or coating insulating powder to form insulating barrier.Winding around on the coiling leg of iron core, the magnetic line of force of magnetic field of permanent magnet pass the coil tooth on the iron core, and coil cutting magnetic line is output current or power.

For ease of winding around on the coiling leg of iron core; Iron plate (punching) forms T type tooth in outer rim; The folded riveting of some moulding iron plates (punching) just forms the flank of tooth in outer rim in the back together, and axially the both sides of upper core are provided with baffle plate, in order to the spacing coil that is wrapped on the coiling leg; Common structure has following two kinds: 1. baffle plate is made up of insulation framework entirely; Baffle plate is being provided with axial bending part with the corresponding position of iron plate (punching) flank of tooth, because bending part is that insulating material such as plastics constitute entirely, intensity is on the low side; 2. for improving the intensity of the axial bending part of insulation barrier outer rim, outermost iron plate (punching) is in the position also axially bending of outer rim corresponding to the flank of tooth, and embeds in the insulation framework.In existing known iron core with above-mentioned the 2nd kind of version, the people is arranged in order to increase the magnetic flux that iron core teeth portion imports coil, improve power output; The axial bending part of outermost iron plate is changed into and the identical arc surface of other iron plate flank of tooth curvature by the plane; But radially all be lower than the flank of tooth, the magnetic conduction gap is different, embeds that part of magnetic conduction excesssive gap in the insulation framework; Magnetic property lost efficacy basically, did not therefore really play the effect that improves power output.

The utility model content

It is reliable that the purpose of the utility model provides a kind of mechanical strength, obviously increased magnetic conductive area under the equal conditions, thereby improve the iron core that is used for generator or motor of power output.

For realizing above-mentioned technical purpose; The said iron core that is used for generator or motor of the utility model; Comprise by the folded riveting iron core body together of iron plate and the insulation framework of iron core body both sides; The both sides of iron core body respectively have one to have the iron plate of axial bending part in outer rim, and this bending part lateral surface is exposed and be and the concordant arc surface of other iron plate correspondence position flank of tooth.

Because the vertical bending part lateral surface of iron core both sides iron plate and the iron core flank of tooth flush and expose, their magnetic conduction gap is identical, and it is long-pending to have increased coil magnetic conduction window tangent plane greatly, has increased magnetic flux density, thereby improves the power output of generator or motor.

Further, said bending part medial surface also is an arc surface, the axially vertical bending of bending part; The bending part medial surface is being supportted by insulation framework; Make bending part identical, prevented low, the yielding problem of the intensity that original vertical bending brought, improved the mechanical strength of iron core with the iron core teeth curvature of face.

Further, the circumferential arc length of said bending part is identical with the circumferential arc length of other iron plate correspondence position flank of tooth, also promptly is consistent at the width of the bending part that makes progress in week and the flank of tooth of correspondence position, is equivalent to extend in the axial direction the flank of tooth.

The utility model has under equal conditions increased the magnetic conductive area of iron core, has improved power output, and the mechanical strength of iron core magnetic conduction face is high, and manufacturing process is simple, and cost is low.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is specified.

Like Fig. 1, shown in Figure 2; The said iron core that is used for generator or motor of the utility model; Comprise by the folded riveting of the iron plate iron core body 1 together and the insulation framework 2 of iron core body both sides; The both sides of iron core body 1 respectively have one to have the iron plate 11 (referring to Fig. 3) of axial bending part a in outer rim, and bending part a lateral surface is exposed and be and the concordant arc surface of other iron plate correspondence position flank of tooth b.Two iron plate 11 bending part a are identical with the magnetic conduction gap that is in all the iron plate flank of tooth that stack between them; It is long-pending to have increased whole iron-core coil magnetic conduction window tangent plane greatly; Increased magnetic flux density; Make the effect that bending part has really played increases magnetic conduction, thereby improve the power output of generator or motor.

Like Fig. 1, shown in Figure 3; Bending part a medial surface also is an arc surface; The axially vertical bending of bending part a, bending part a medial surface is being supportted by insulation framework 2, makes bending part a identical with iron core flank of tooth b curvature; Prevent low, the yielding problem of the intensity that original vertical bending brought, improved the mechanical strength of iron core.

The circumferential arc length of bending part a is identical with the circumferential arc length of other iron plate correspondence position flank of tooth b, that is to say, is consistent at the width of the bending part a that makes progress in week and the flank of tooth of correspondence position, is equivalent to extend in the axial direction the flank of tooth, improves the magnetic conductive area of whole iron core.
