EDKR(AT)225M2 BP
Asynchronous EDKR motors(AT)225M2 VRs 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 installations of mines and mines.
Nominal values of the main engine parameters in the S1 mode according to DSTU IES 60034-1 are given in the table. Permissible deviations from the nominal values of indicators according to DSTU IES 60034-1.
It is allowed to operate engines in mode S2 = 60 min, S3, S4 – 60% with the inertia factor F = 2 and frequency of inclusions to 30 included per hour, at the same time, the permissible power value is no more, specified for mode S1.
