EDKR(AT)315M8 AND

Asynchronous EDKR motors(AT)315M8 VA are designed to work from an alternating current network with a frequency of 50 Hz with isolated neutral of coal mines and mines, dangerous due to the content of mine gas (methane) and (or) coal dust as a drive for stationary machines and mechanisms (pumps, fans, compressors), as well as drives of other mechanisms and machines with similar modes of operation. Nominal values ​​of the main engine parameters in the S1 mode according to DSTU IES 60034-1 are given in the table.
