Electric motor 18,5 kW, 985 rpm, 400 V / 690 V, 4LC-200L1-6 LV

Unlike solutions with lower IE2 or IE3 efficiency, this electric motor offers more thoughtful engineering, which reduces energy losses in both normal and demanding operation. The 4LC-200L1-6 model with an output of 18.5 kW operates in the speed range of 900-1000 rpm, so it naturally fits applications where a balanced ratio of torque, flow and reliable operation is important. Advanced materials, sophisticated windings, and VYBO Electric’s own research and development support stable operation even where long-term load is expected.

Higher efficiency in pump, fan and compressor operation

For operators of pumps, fans, compressors and large machines, it is not only the rated value that matters, but also the ability to maintain efficiency throughout the entire working cycle. This motor achieves an efficiency of 93.4% and a power factor of 0.8, which helps reduce operating losses in low-voltage infrastructure. The rated current at delta 400 V is 35.3 A and at star 690 V is 20.5 A, so the designer can integrate the motor into standard connections with regard to grid conditions.

Speeds suitable for slower industrial drives

Rated speed of 985 rpm, starting torque ratio Tst/Tn of 2 and breakdown torque ratio Tmax/Tn of 2.1 create a practical basis for drives that must overcome load without unnecessary shock behaviour. The starting current ratio Ist/In of 8.5 is important when assessing the power supply system and protective elements, especially in equipment with frequent starts.

Construction that helps maintain stability under long-term load

The all-cast iron design with an IEC frame of 200 mm supports mechanical strength and contributes to better vibration suppression in demanding conditions. Noise level of 73 dB(A) remains at a reasonable level for industrial use, and the packing weight of 248 kg indicates robust workmanship suitable for operations with higher demands for durability. Rotor inertia of 0.4 kg*m² helps to balance drive dynamics, which is especially appreciated by operations with longer working cycles.

• Pumps will benefit from stable operation when conveying liquids with high operational reliability.
• Fans benefit from speeds that are well suited to long-term air circulation.
• Compressors gain a motor suitable for reliable starting under load.
• Large mixers will use a solid base for smooth torque transfer.
• Industrial conveyors will appreciate the balanced ratio of output and speed.
• Gear reducers can rely on a stable input for further mechanical stages.
• Process lines gain a motor that fits well into long-term production cycles.
• Pressing equipment benefits from resistance to repeated mechanical stress.
• Machine assemblies will use a robust design under continuous load.
• Production units with higher dust levels appreciate the all-cast iron solution with better corrosion protection.
• Drives with a frequency converter can operate in a stably controlled mode.
• More aggressive industrial environments gain a design prepared for longer service life.
• Low-speed industrial applications benefit from speeds suitable for controlled energy transfer.

Connection, bearings and winding protection for reliable integration

The motor is equipped with 2-M50X1.5 cable glands, a DE 6312-C3 bearing and an NDE 6312-C3 bearing, which makes it easier to incorporate into service-proven assemblies. The PTC winding protection accessory increases confidence under thermal stress and helps prevent damage at times when operation is working at the limit of load. This design is suitable for drives where long-term reliability without unnecessary downtime is important.

If you are looking for a solution for pumps, fans, compressors or heavier industrial assemblies, this electric motor offers a sensible combination of efficiency, mechanical durability and easy integration into existing technology.
