Electric motor 200 kW, 740 rpm, 400 V / 690 V, 4LC-355L2-8 LV

When selecting a motor for continuous production, it is worth choosing a solution that reduces energy losses and service downtime; that is why the 4LC-355L2-8 model with an output of 200 kW is suitable for operation in the 700-750 rpm range and for applications where substantial cost savings are expected over the long term. It is a low-voltage asynchronous electric motor designed for large installations in which smooth operation, robust mechanics and the ability to work under high operating load without unnecessary overheating are decisive.

Higher efficiency in operations with a constant load

An efficiency of 95.4% and a power factor of 0.82 help to reduce operating costs under long-term load, which is especially important for an energy-saving industrial motor in continuous production cycles. The rated current with a delta connection at 400 V is 373 A and with a Y connection at 690 V is 216.2 A, so the drive can be correctly integrated into different voltage systems. The starting ratio Ist/In 7.8, the starting torque ratio Tst/Tn 1.6 and the breakdown torque ratio Tmax/Tn 2 provide an overview of the motor’s behaviour at start-up and during short-term dynamic load changes.

• Large-scale production technology gains a reliable drive with high operating stability.
• Drive units in production installations benefit from a balanced ratio of power, current and speed.
• Conveyors in metallurgical and processing lines profit from smooth engagement and low sensitivity to load fluctuations.
• Grinding mills and crushing equipment use a robust design for impact loads.
• Compressor stations gain a stable operating mode during long duty cycles.
• Pumping systems in large facilities benefit from constant speed and durable bearing arrangement.
• Ventilation and extraction units use power reserve for continuous airflow.
• Extruders and similar technological equipment benefit from low-speed industrial applications with an emphasis on stable torque.

Mechanical durability for aggressive environments

The 355 mm frame size and all-cast iron construction support the strength of the assembly, vibration damping and corrosion resistance in aggressive environments. A package weight of 1884 kg and a rotor inertia of 14.2 kg*m² confirm that this is a substantial drive ready for integration into heavy industrial infrastructure. Noise level of 89 dB(A) is a value that must be taken into account when designing the machine room, enclosure and acoustic measures across the entire technological block.

Installation and electrical details for integrators

The 2-M63X1.5 cable entries make it easier to route supplies in space-demanding installations, and the DE 6322-C3 and NDE 6322-C3 bearings support reliable operation under long-term load. Accessories include 3 PTC thermistors, which help with thermal monitoring of the winding and increase the safety of connection in production applications with variable operating modes. Precise mechanical dimensioning is also important for technical teams, so the package dimensions of 1660*840*1160 mm make it easier to plan transport, storage and handling at the installation site.
