The invention relates to the field of electrical engineering, namely to electric machines of the reciprocating simultaneously oncoming traffic and actuators operating on the basis of them.

Known electromagnetic motor comprising a cylindrical stator winding, disc anchors, two identical working air gaps, recoil, casing and two coaxial cylinders fixed to the inner plane of the disk, resulting in movement of the working body of the press (As the USSR №855888, IPC NC 33/02, publ. 15.08.1981 year). This engine is designed for direct military action and its stator is fixed on the reverse impact forces on the engine base or a special bed on which it is installed.

The disadvantage of this analogue is the lack of use in a small Electromechanical devices and manual tools, because the engine through the direct work has the reverse impact strength of bestowal, this creates a strong vibration motor housing and complicated structure.

Also known linear electromagnetic actuator press (RF Patent No. 2193943, IPC B21J 7/30, WV 1/42, publ. 10.12.2002,), where the electromagnetic motor includes a stator placed in it by winding and an anchor, the guide casing with a focus and a return spring. The anchor consists of two moveable is x relative to each other parts. One part is a Cup, and the second is located inside a cylindrical glass core. The cross-sectional area of the glass is less than the cross-sectional area of a cylindrical Cup. In the upper part of the Cup and core are the shoulder. Anchor in the initial position is set with the condition that the distance between the bead core and focus of the guide casing is less than the magnitude of the stroke of the armature.

The disadvantage of this analogue, as well as the previous one, is the lack of the possibility of its use in hand power tools due to strong vibration.

Also known linear motor of the reciprocating motion (A.S. USSR №1725330, IPC NC 33/00, H01F 7/16, publ. 07.04.1992 g)containing the stator magnetic core and the coil in the cavity where the anchor with an axial blind hole, in which is placed an adjusting screw for regulating the amplitude of the stroke of the motor armature, a return spring.

The disadvantage of this analogue is also the lack of ability to use hand / power tools due to strong vibration.

The closest in technical essence and the achieved effect is electromagnetic actuator reciprocating motion (A.S. USSR №1453544, IPC NC 33/02, publ. 23.01.1989 g)containing a cylindrical inductor, consisting of m is of gnathopod and winding, located in the annular groove of the magnetic circuit, while the inner cylindrical surface of the cylinder formed by the inner cylindrical surfaces of the poles of the magnetic circuit and windings, and coaxially located movable anchor, consisting of two parts, containing ferromagnetic and electrically conductive elements, a return spring and two identical parts that complement one another to a full cylinder, each of which consists of ferromagnetic and attached to its end placed inside the inductor, electrically conductive elements, the anchor is located symmetrically relative to the coil, a return spring mounted in the axial channel of the anchor formed by a blind end grooves in its parts, and is backed by their ends on different parts of the anchor.

The disadvantage of the prototype is inefficient magnetic system, because the anchor is not solid ferromagnetic body, and consists of two longitudinally divided parts, oriented counter to their movement, so that the magnetic flux of the winding is divided into the moving parts, which reduces the efficiency of the engine. Furthermore, the design of the prototype is far from practical application and requires serious revision.

The present invention is to reduce the level of vibration elektrodvigatel what I increased productivity and efficiency.

The technical result is to increase the level of safety in the operation of the linear electromagnetic motor of the reciprocating motion, to reduce the power consumption due to pulsed electromagnetic power of the engine, to increase productivity and efficiency.

This object is achieved in that the electromagnetic motor of the reciprocating movement, containing a cylindrical inductor consisting of a magnetic core and winding, placed in the annular groove of the magnetic circuit, coaxial counter-spaced anchors backward and forward movement, a return spring mounted in the axial channel formed by end blind grooves in the anchor forward stroke and the anchor reverse, according to the proposed technical solution, the anchor of the forward stroke and the anchor reverse made in the form of rigidly interconnected disk and cylindrical parts, while the cylindrical part have an excellent largest diameter, and the cylindrical portion of the armature forward stroke has an internal blind groove, the diameter of which is larger than the diameter of the cylindrical part of the anchor-reverse, which is arranged to move inside the groove of the anchor forward stroke, the disk part of the Yak the ray directed to different poles of the cylindrical inductor, while at anchor forward stroke has an axial rod and anchored reverse has an axial opening in which is movably axial rod anchors forward stroke.

Comparative analysis with the prototype shows that the claimed electromagnetic motor of the reciprocating motion differs in that it contains two counter-directed ferromagnetic anchor of the same mass, where the disk portion of the anchor is directed to a different end poles of the cylindrical magnetic core of the inductor, while the axial rod anchors forward stroke passes through the axial hole of the anchor reverse.

Thus, the claimed electromagnetic motor of the reciprocating motion meets the criteria of the invention of "novelty."

The comparison of the proposed solutions not only prototype, but also with other technical solutions in this field of technology is not allowed to reveal in them the features distinguishing the claimed solution to the prototype, and the introduction of two counter-directed magnetic anchors and axial counter-movement of the armature of a direct stroke in a through axial hole anchors reverse allowed to make a conclusion about the technical solutions according to the criterion of "significant differences".

The invention is illustrated by drawings, where figure 1 presents prodol the first section of the electromagnetic motor of the reciprocating movement, where the positions indicated:

1 is a cylindrical magnetic core of the inductor;

2 - excitation winding;

3 - anchor forward stroke;

4 - anchor reverse;

5 - disc portion of the anchor forward stroke;

6 is a cylindrical portion of the armature forward stroke;

7 - disk part of the anchor reverse;

8 is a cylindrical portion of the armature reverse;

9 - internal blind groove anchors forward stroke;

10 is an axial rod anchors forward stroke;

11 - a through axial hole anchors reverse;

12 - end blind groove anchors the forward and reverse;

13 - recoil;

14 - pole inductor for anchors forward stroke;

15 - pole inductor for anchors reverse.

The electromagnetic motor of the reciprocating motion comprises a cylindrical inductor consisting of a magnetic core 1 with the excitation winding 2, placed in the annular groove of the magnetic circuit, two coaxial counter located anchor forward stroke 3 and reverse 4, which are made in the form of rigidly interconnected disk part 5 and the cylindrical part 6 of the anchor forward stroke 3 and the disk portion 7 and the cylindrical part 8 of the armature backstop 4 (figure 1). Cylindrical portions 6, 8 of the anchor forward stroke 3 and anchors reverse 4 respectively have different size diameters. The cylindrical part 6 of the armature of the direct Hoda has an internal blind groove 9 depth 2δ, a diameter larger than the diameter of the cylindrical part 8 of the armature backstop 4, and provides a gap between them. The cylindrical part 8 of the armature backstop 4 is arranged to move in the inner hollow groove 9 of the armature forward stroke 3. Anchored forward stroke 3 has an axial rod 10 and anchored reverse 4 has a through axial hole 11 which is movably axial rod 10 anchors forward stroke 3. The diameter of the axial rod 10 anchors forward stroke 3 and the diameter of the through hole 11 of the armature backstop 4 made, for example, with a running landing. Both anchors in the internal cylindrical parts have mechanical deaf grooves 12, in the axial channels which has a return spring 13. Disk part 5, 7 anchors forward stroke 3 and reverse 4 respectively directed to different poles 14, 15 of the cylindrical magnetic core of the inductor 1 and separated from it by a distance δ, equal to the gap. Internal blind groove 9 of the armature forward stroke 3 has a depth not less than twice the working gap 2δ. Anchor forward stroke 3 is equal to the weight of the anchor reverse 4.

The electromagnetic motor of the reciprocating motion is as follows. When applying a pulse voltage to the field winding 2, a magnetic flux, which causes at the same time a counter is offered by the movement of the anchors forward stroke 3 and reverse 4, while the anchors forward stroke 3 and reverse their 4 disc parts 5 and 7 simultaneously attracted to the poles 14 and 15 of the cylindrical magnetic coil 1, is oncoming traffic anchor. When the movement of the cylindrical part 8 of the armature backstop 4 is included in the inner blank groove 9 of the armature forward stroke 3. In the oncoming traffic anchor forward stroke 3 and reverse 4 is compressed return spring 13 located in the remote end of the grooves 12 of the armature 3 direct and reverse 4, wherein the anchor reverse 4 moves its end-to-end axial hole 11 on the axial rod 10 anchors forward stroke 3. By removing the voltage from winding 2 anchor forward stroke 3 and the anchor reverse 4 under the force of the compressed return spring 13 returns to its original position. When applying a series of voltage pulses to the excitation winding 2 of the electromagnetic motor of the reciprocating movement operates in pulsed mode without vibration.

The presence of anchors forward stroke 3 and reverse 4 having a cylindrical 6, 8 and the disk part 5, 7, respectively, allows you to fully utilize the useful magnetic flux passing through both the armature 3, 4 and the cylindrical magnetic core of the inductor 1, creating the greatest force on the axial rod 10 anchors forward stroke 3. Furthermore, the design strategyplanning movements anchor eliminates strong vibration of the engine and increases its reliability.

Running the anchor forward stroke 3 is equal to the weight of the anchor reverse 4 contributes to the fact that when applying a pulse voltage to the field winding 2, the magnetic flux and the mechanical force of attraction of the armatures 3, 4 is uniformly distributed on the anchor forward stroke 3 and reverse 4, which also helps to reduce vibration of the engine and increases its reliability.

Thus, the increased level of safety in the operation of the electromagnetic motor of the reciprocating motion, reduced power consumption due to its pulsed power, increases productivity and efficiency, as well as improving the environmental friendliness of the workplace.
