Electric motors of the Direct current D818
Engines low-speed series D are intended for work in electric drives of hoisting-and-transport mechanisms of metallurgical units and live rolls in the long, short-term and repeated and short-term modes in the conditions of the increased humidity, dust content and vibration (for example, rolling, steel-smelting and domain shops).
Engines are characterized by high reloading ability and wide range of regulation of frequency of rotation.
Are delivered in the closed execution with natural cooling, and also in protective execution with independent ventilation with air supply through tunnel pipes from the air route, or from the fan equestrian.
Degree of protection of engines of the closed execution — IP44, by delivery to export — IP54.
Engines are manufactured on the rated voltage of 220 V and 440 V with ways of excitement: consecutive, mixed, parallel and parallel with the stabilizing winding. For engines operating modes are set: in the closed execution of S2 — 60 min., S3 — 15%, 25%, 40%, 60% and S1, in the protected execution — the S1 mode.
Engines are manufactured with designs on a way of installation IM1003, IM1004, IM4014 in accordance with GOST 2479.
By request of consumers engines can be delivered with adjusting and connecting sizes according to the publication MEK 34-13, with terminal boxes and precision tacho generators.
Engines allow to carry out regulation of frequency of rotation by change of the brought tension and extent of excitement.
Engines correspond to GOST 183-74, the publication MEK 34-13, are issued on TU 16-87 of Irak.524314.003tu.
For the drive of live rolls engines have special execution with the lowered rotation frequency.
Electric motors of a series D have certificates of conformity on safety of Gosstandart of the Russian Federation.
Warranty period for engines — 3 years from the date of input of the engine in operation, but no more than 3,5 years from the date of receiving by his consumer.
