The ECVD series motors are the advanced analogues of the SG series electric motors manufactured by Damel (Poland) and are used as part of the combine harvesters of the MB series produced by T-Machinery in the Czech Republic and for the drive of a coal-mining machine for long lavas 4SL20 produced by JOY MININGMACHINERY (USA).

State Enterprise "Donetsk Electrotechnical Plant" has experience in manufacturing the ECVD motor 3,5-36 36/1500 analogue of the imported electric motor 2SG 4 225 S4 36/1500 which is used on the MR-620 combine.

Electric motor EKVD 3,5-36 36/1500 is made in climatic design IP66 which allows an operation under direct influence of water.

The encapsulation of the stator winding allows the operation of the stator in water has been made.

Electric motor ECVD 3,5-36 36/1500 made it possible to operate the MR-620 without accident in complex mining and geological conditions with a large inflow of water.

Video of engine tests can be found on request "waterproof engine" on the channel "Youtube".

Type and level of explosion protection - РВ 3VIA according to GOST 12.2.020-76, РВ ЕхdiaI according to GOST R 51330.0-99;

Level of protection of motors and terminal box - IP54 in accordance with GOST 17494;

Method of cooling engines - IСW37 according to GOST 20459;

Type of climatic design of engines - U2.5 in accordance with GOST 15150.

Electric motors series ADVR and VKDV have significant advantages over analogues due to the following design features:

  • Double copper-brass squirrel cage of the rotor;
  • Improved insulation system with increased moisture resistance;
  • Improved torque response.
  • Longer operation (of the order of 2-fold increase in comparison with the aluminum rotor);
  • The use of copper-brass rotor eliminates the premature write-off of the engine as non-repairable due to the melting of the aluminum of the rotor, reduces the number of repairs and increases its operating time for failure;
  • an acceptable price in comparison with European counterparts

In addition to the standard series of standard electric motors presented by SE "Donetsk Electrotechnical Plant" the enterprise takes into account the wishes of customers for modernization and non-standard performance of electric motors.


  1. Electric starting equipment.

Explosion-proof intrinsically safe PIDID series:

They are designed to remote control of the switching on and off of asynchronous squirrel-cage induction motors operated in three-phase alternating current networks with a frequency of 50 Hz with an isolated neutral of the transformer in coal mines dangerous for gas (methane) and coal dust, as well as for protection against short-circuit currents. and overload in the outgoing power circuits. Manufactured in reversible and non-reversible designs. The starters do not emit electromagnetic interference on the control, protection, telecommunications circuits involved in the common cable network of the site. Types of climatic performance of starters УХ Л 5 in accordance with GOST 15150, explosion protection - РВ-3В Iа.

- supply voltage - 660 / 380V, 1140 / 660V.

- kinds of contactors - air, vacuum.

According to the customer’s request all starters can be equipped with Hansen contactors and units.

Automatic circuit-breakers AVD

Designed to protect electrical installations from short-circuit currents as well as for operational switching on and off of electrical circuits under normal operating conditions in three-phase AC networks with a frequency of 50 Hz with an isolated neutral when installed in coal mine workings dangerous for gas (methane) and coal dust.

Provide protection: zero, short-circuit currents, blocking when the insulation resistance of the outgoing connection decreases, loss of control when the remote shutdown wires are closed or broken.

An additional voltage indication function is introduced in the AED-DO which is absent in analogues and the reliability of the interlocking device of the circuit-breaker is simplified and increased.

Soft starters UVPPD

Are intended for smooth start-up of asynchronous electric motors in coal mines, dangerous on gas (methane) and coal dust. Equipped with a thyristor module, which provides a smooth torque boost during start-up.

The devices are made in a single compact housing and perform all the functions of the starter.

It is allowed the connection of two or more engines subjected to their total operating current is not more than the rated current of the device.

UVPPD -315 is characterized by the fact that the contactors are connected in series which allow to disconnect the device in an emergency situation when welding contactor contacts.

Explosion-proof transformer substations of the VSTP with a capacity of 630, 1000 kVA.

Substations of the VSTP type are designed to supply three-phase current to current collectors installed in underground mine workings that are dangerous for gas (methane) and coal dust as well as to provide protection against leakage currents and overcurrent protection including combined networks according to the "Safety in coal and shale mines rules ".

Substations are designed for both the domestic market (GOST 16837, GOST 22782.0) and for supplies to Russia and the CIS countries.

Type of climatic performance of substations - UHL 5 and T 5 in accordance with GOST 15150.
