Electric motor 250 kW, 2980 rpm, 400 V / 690 V, 4LC-355M2-2 LV

Compared with an IE2 or IE3 solution, the 4LC-355M2-2 with an output of 250 kW and rated speed of 2980 rpm. provides more scope for economical operation, especially where stable running is expected in the range 2900-3000 rpm. The motor uses advanced materials and sophisticated winding design, which support long-term efficiency in low-voltage applications in modern production facilities.

Efficient operation in the speed range 2900-3000 rpm.

This IE4 electric motor is suitable for drives that need high operational reliability and consistent performance when supplied at 400 V or 690 V. The rated current reaches 411 A with delta 400 V connection and 238 A with star 690 V, while the power factor of 0.91 helps with stable grid loading. The efficiency of 96.5 % supports reduced losses and better energy management in long operating cycles.

Construction ready for demanding environments

The all-cast iron design with a frame height of 355 mm is intended for rigid mounting, good vibration absorption and resistance to external influences. The noise level of 97 dB(A) corresponds to the 250 kW output class and industrial use, where suitable installation and service access are also important. The package weight of 1606 kg and package dimensions of 1607*822*1161 mm make handling planning easier during installation and drive replacement.

Industrial applications of the electric motor

The motor is used in drives for light and heavy industry, in pumps, compressors, fans, conveyors, mixers, gear units, process lines, processing equipment and high-speed applications where a solid performance base is required. For starting and dynamic loads, the ratios Tst/Tn 1.6, Tmax/Tn 2.2 and Ist/In 8.5 are important, as they help to estimate behaviour in real operation.

Detailed features for reliable integration

The bearing arrangement DE 6319-C3 and NDE 6319-C3 supports the stable rotor mechanics, whose moment of inertia is 3.4 kg*m². The cable entries 2-M63X1.5 make connection easier in switchboard and machine assemblies, while the 3 PTC thermistors increase winding protection through temperature monitoring. Given these parameters, the motor is suitable for projects where long service life, service reliability and a precisely selected power rating are required.
