Known electromagnetic vibration motor [Pat. 2526852, Н02K 33/02, Н02K 1/06. The electromagnetic engine (options) / L.A. Neumann, V.Yu. Neumann, O.V. Rogova. - No. 2012146808/07; declared 11/01/12; publ. 08/27/14, Bull No. 24. - 7 p.] Containing a cylindrical magnetic core consisting of a core, a coil located on the core and an external forward armature with a ferromagnetic shunt; annular protrusions are made along the length of the outer and inner diameters of the ferromagnetic shunt with a step equal to the step of the diameter-conjugated ring protrusions formed along the outer diameter of the core and the inner diameter of the casing of the magnetic circuit.

The disadvantages of this technical solution include the complexity of winding the coil on the core, which reduces the manufacturability of the manufacture of an electromagnetic vibration motor.

Closest to the claimed invention in technical essence is an electromagnetic vibration motor [Pat. 112722 F04B 45/00. Electromagnetic compressor / V.Yu. Neumann, O.V. Rogova. - No. 20111133626/06; declared 08/10/11; publ. 01/20/12, Bull No. 2. - 2 pp.], Which is a prototype, comprising a housing, a core located in it with poles with coils placed on them, and an anchor interacting with them spring-loaded with elastic elements.

The disadvantages of this technical solution include the complexity of winding coils on the poles of the core, which reduces the manufacturability of the manufacture of an electromagnetic vibration motor.

The objective (technical result) of the utility model is to increase the manufacturability of the manufacture of an electromagnetic vibration motor.

This task is achieved by the fact that in the electromagnetic vibrator containing the housing, the core located in it with poles with coils placed on them and the armature spring-loaded with elastic elements interacting with them, the core poles are made in the form of separate structural elements and installed in the grooves of the core after winding on them coils, which increases the manufacturability of the manufacture of an electromagnetic vibrator. Moreover, the screed with screws located in the removable covers of the casing of the electromagnetic vibration motor provides rigid fixation of the poles of the core in its grooves.

In FIG. 1 shows the design of an electromagnetic vibrator.

In FIG. 2 shows a sectional view of the construction of an electromagnetic vibrating motor. View from above.

The electromagnetic vibrator contains a housing 1 with removable covers 2, 3, a core 4 located in it with poles 5, 6 (Fig. 2), with coils 7, 8 placed on them and the armature 11, spring-loaded with elastic elements 9, 10, interacting with them.

The poles of the core are made in the form of separate structural elements and are installed in the grooves of the core after winding coils on them. Moreover, the tight fixation of the poles of the core in its grooves is ensured by the screed with screws located in the removable covers of the body of the electromagnetic vibration motor.

Electromagnetic vibrator operates as follows.

In the initial state (Fig. 1), the armature 11 is located between the poles of the core 5, 6 so that its annular protrusions are at a distance equal to half the length of the mating annular protrusions of the poles.

When an alternating electric current flows through the coils 7, 8 connected to an alternating current source, an alternating magnetic flux is closed in the core 4, poles 5, 6 and the armature 11. Under the influence of electromagnetic forces arising in the annular protrusions, and the elastic forces of the elements 9, 10, the armature 11 makes reciprocating movements relative to the stationary core 4 and the poles 5, 6, fixed in the grooves of the core.

Since the magnetic flux is variable, when the flux changes and it is equal to zero, the electromagnetic force applied to the armature 11 also becomes equal to zero. Due to the compression force of the lower spring-loaded elastic element 10, the armature 11 returns to its initial state before the arrival of the next current pulse.

The technical result is to increase the manufacturability of the manufacture of an electromagnetic vibration motor due to the fact that the poles of the core are made in the form of separate structural elements and are installed in the grooves of the core after winding coils on them. Moreover, rigid fixing of the poles in the grooves of the core is ensured by the screed with screws located in the removable covers of the casing of the electromagnetic vibration motor.

Thus, this technical solution improves the manufacturability of manufacturing an electromagnetic vibrator in relation to the prototype by performing the core poles in the form of separate structural elements and installing them in the grooves of the core after winding coils with a tight coupler with screws located in removable covers of the body of the electromagnetic vibrator, the core poles in it grooves.
