Asynchronous explosion-proof EKVD motors are designed for operation from an alternating current network in the composition of drives of cleaning combines and other machines and mechanisms with similar operating modes including in the frequency-controlled drive for operation in mines and mines dangerous for mine gas content (methane) and coal dust.
The engine EKVD4-180TV is designed to drive the working bodies of coal-cleaning combines equipped with electric motors SG7W455L-4 produced by Damel (Poland), the EKVD5-285T engine is designed to drive a coal-mining machine for long lavas 4SL20 (manufactured by JOY MINING MACHINERY), EKVD3.5- 22-01 is designed to drive the feeding of the coal-mining machine MB410E produced by T Mаchinery a.s. (Czech Republic).
Technical characteristics of electric motors are given in the table. The work in the frequency-controlled drive is specified when ordering.
