Description

() ELECTROMAGNETIC MOTOR OF RETURN MOTION

one

The invention relates to electromagnetic shock mechanisms, in particular to electromagnetic motors with a propulsion motion of the movable part.

Known electromagnetic motor with reciprocating motion of the movable part, for example, the engine hammer Saratovets-2 1.

However, this engine has low efficiency and low specific energy of impact.

The closest to the invention in technical essence and the achieved effect is an electromagnetic motor of reciprocating motion, comprising a stator with coils of forward and reverse stroke with the same winding direction and ferromagnetic measles 23 connected in parallel through valve elements.

The disadvantage of this engine is low efficiency due to additional losses from crustal streams.

And parasitic stresses caused by large time constants in coils. chains of valve elements, as well as relatively low electromagnetic traction forces 2. The purpose of the invention is to increase efficiency.

The goal is achieved by the fact that an annular bore is made in the engine in the cortex, in which the winding is placed, with winding, opposite to the direction of the winding of the coils of the forward and reverse gears.

The drawing shows a reciprocating electromagnetic motor.

The engine consists of a forward coil 1 and a reverse coil 2. Each coil is enclosed by a laminated magnetic core 3 with two

20 extreme and one middle poles. The coils are wound clockwise (in drawing H, the start of the winding, and k is the end of the winding). 393 Coils 1 and 2 are connected in parallel with the opposite direction of the MDS coils of the forward and reverse stroke. The armature k is a ferromagnetic solid body, with a substantially substantially circular cross section with an annular bore into which the coil 5 is placed. The coil is prevented by the ferromagnetic cover 6 from falling out of movement of the bark. 6, a hole was made into which wires were passed to connect to the terminals of the coil 5. I To reduce the influence of vortex flows around the perimeter of the core, longitudinal slots of the Sleep slot are not shown in the drawing). The bark reciprocating movement is carried out along the j direction non-ferromagnetic sleeve placed in the inner diameters of coils 1 and 2. Coils 1 and 2 are connected in parallel and connected to the AC network through counter-parallel diodes 8 and 9. into the AC network. The machine works as follows: working mode (movement of the core from right to left). In this case, coil 1 is working and the core is moving under the influence of the electromagnet NOY of the power of the RZD created by the working current of the fr. However, besides the main flow, there is also a parasitic flow FR, closing through the extreme pole of the magnetic circuit 3. Without the flow created by the coil 5 F | This parasitic flow has an inhibiting effect on the motion of the core. However, when the coil is turned on 5, the flow of FC is directed oppositely to the flow fr. Consequently, at the end of the core, opposite to its motion, a force Fd arises in accordance with the main electromagnetic force. This force has the greatest magnitude at the beginning of the motion of the core, and then decreases. Flow f | generated by the coil 5, increases the magnitude of the electromagnetic force, as it is directed in accordance with the working stream Fr. The flux Φ | (does not overcome the parasitic gaps created by the presence of a non-ferromagnetic sleeve 7. These two factors also lead to an increase in the total electromagnetic force compared to the known engine, and hence the energy performance of the proposed engine. stroke 2 and the measles under the action of the electromagnetic force generated by this coil, begins to move in the opposite direction. The magnetic flux F | coil 5 also changes the sign and the whole picture of the physical processes The second invention is achieved. This embodiment of the reciprocating electromagnetic motor makes it possible to increase the efficiency of the machine by a factor of 1.5. Invention Electromagnetic reciprocating engine containing a stator with coils connected in parallel through valve elements retraction with the same direction of winding and ferromagnetic measles, which is also distinguished by the fact that, in order to increase efficiency, an annular boring is made in the core, in which oh there is a winding with a winding opposite to the direction of the windings of the forward and reverse coils.
