Electric motor 37 kW, 2970 rpm, 400 V / 690 V, 4LC-200L2-2 LV

When selecting a drive for pumps, fans, compressors or larger machines, it is worth choosing a solution that can handle long-term load without unnecessary losses. The 4LC-200L2-2 model with an output of 37 kW for 400 V / 690 V and operating in the range 2900-3000 rpm delivers exactly that kind of operating mode, in which noticeably lower energy consumption and more stable operation can be achieved in year-round service. In practice, it is a choice that supports significant cost savings, especially where the motor operates for many hours a day.

This IE4 electric motor is designed for demanding industrial use, where the combination of high efficiency, mechanical durability and reliable starting reserve is important. With an efficiency of 94.8 % and a power factor of 0.89, it helps reduce operating losses, while the starting torque with a ratio of Tst/Tn 2 and the breakdown torque with a ratio of Tmax/Tn 2.3 provide confidence at start-up and when the load fluctuates. The starting current Ist/In 9 should be taken into account when designing the switchboard and protection, especially in systems with more sensitive low-voltage infrastructure.

Energy savings in long-term operation in the 2900-3000 rpm range

In segments with continuous operation, it is important for the motor to save not only energy, but also the maintenance budget. Precisely for this reason, the low-voltage asynchronous electric motor with a centre height of 200 mm is suitable for assemblies where stable performance and durability under repeated load are expected. The noise level of 84 dB(A) remains within parameters that are common for many industrial spaces, and therefore the motor is also suitable for halls, technical rooms or outdoor technology units.

• The rated current with delta connection 400 V is 63.3 A, which makes starting design and supply cable sizing easier.
• The rated current with Y connection 690 V is 36.7 A, which allows flexibility under different network conditions.
• The rotor inertia of 0.2 kg*m² supports a quick response of the drive at start-up and when the load changes.
• The 6312-C3 bearings on both the DE and NDE sides increase suitability for long-term industrial operation.
• The 3 PTC thermistors help with thermal winding protection and better monitoring of operating conditions.

Use in drives with high demands on reliability

In environments where the motor is expected to start smoothly and deliver stable performance under high load, a design with robust support and well-considered cooling proves its worth. The packaging weight of 263 kg, packaging dimensions of 862*492*656 mm and 2-M50X1.5 cable glands make logistics and mounting into prepared frames or base plates easier. This type is therefore suitable for installations where quick integration into an existing technological unit is important.

Industrial applications of the electric motor

• Pumping stations with a requirement for stable pressure and long-term operation.
• Fans for air handling, extraction and process cooling.
• Compressors in operations with regular or continuous compressed air demand.
• Drives and units of large machines in heavy manufacturing.
• Technological lines with higher inertia and frequent loading.
• Industrial pumps for water supply and process systems.
• Air management in small and medium-sized manufacturing plants.
• Solutions for high-speed applications where efficient operation in a speed class close to rated speed is important.
• Operations with a 400 V or 690 V network, where connection adjustment is required.

Construction for demanding environments and reliable installation

The robust cast iron construction helps limit vibration and increases resistance to corrosion, which is beneficial in aggressive environments as well as in operations with higher dust levels or humidity. Thanks to the fully cast-iron design, the motor behaves firmly even under long-term mechanical stress and fits better into a professional range for industrial use. The VYBO Electric brand builds its portfolio on its own research and development, offering solutions intended for reliable integration into modern drive systems.

If you need a motor for an application where efficiency, stability and service confidence are decisive, this model represents a sensible basis for a project or for replacing an existing drive.
