Electric motor 110 kW, 990 rpm, 400 V / 690 V, 4LC-315L1-6 LV

Compared with an IE2 or IE3 solution, this motor delivers a higher operational benefit where energy is converted for long periods without interruption. 4LC-315L1-6 with an output of 110 kW and a speed of 990 rpm belongs to the 900-1000 rpm segment, which in practice helps reduce losses and achieve a noticeable cost saving when upgrading a drive. For plants, technology suppliers and operations with low-voltage infrastructure, this is a low-voltage asynchronous electric motor that builds on the in-house research and development of the VYBO Electric brand and fits into a professional range for industrial deployment.

The electrical parameters are designed for reliable connection in production units with a requirement for 400 V and 690 V. The rated current in delta 400 V connection is 193 A and in star 690 V connection it reaches 111.9 A, which supports flexibility when designing switchgear and when replacing existing drives. The power factor of 0.85 and efficiency of 95.8 % correspond to operation where long-term energy balance and control of thermal load are monitored.

The motor starting behaviour is suitable for applications requiring a controlled start and firm engagement. The starting torque ratio Tst/Tn is 1.6, the breakdown torque ratio Tmax/Tn is 2 and the starting current ratio Ist/In is 8. The rated speed of 990 rpm together with the rotor inertia of 6.2 kg*m² make it easier to integrate into assemblies where both starting dynamics and steady-state stability need to be taken into account. Noise level of 83 dB(A) remains within the range common for robust industrial drives of this power class.

Operation in the 900-1000 rpm range for long-term energy efficiency

This motor is suitable for processes that require stable torque and precisely controlled speed without unnecessary fluctuations. Combined with an efficiency of 95.8 %, it helps reduce operating losses in long operating cycles while also supporting the modernisation of older units that no longer meet energy efficiency requirements. For businesses comparing replacement with a lower efficiency class, this is a solution with a significant economic effect under continuous load.

Construction that withstands vibration and an aggressive environment

The all-cast-iron design with a 315 mm frame provides a solid base for installation in technological assemblies where resistance to mechanical stress and corrosion is required. The robust cast-iron construction helps dampen vibration and protect the motor during long-term operation in demanding conditions. The 2-M63X1.5 cable entries allow practical routing of cables, while the DE 6319-C3 and NDE 6319-C3 bearings support reliability in heavy-duty operation. PTC winding protection increases safety under thermal stress.

Industrial applications of the electric motor

• Pumps benefit from stable operation during continuous media conveyance in process lines.
• Fans benefit from the balanced ratio of power, speed and efficiency.
• Compressors use the firm starting torque during repeated starts.
• Conveyor gear units support smooth material transfer in production lines.
• Mixers appreciate even operation with technological mixtures.
• Crushers and processing equipment use high resistance under shock loading.
• Extruders need stable speed during the precise processing procedure.
• Rotary dryers require reliable drive during long cycles.
• Transport systems in warehouses benefit from robustness during continuous operation.
• Machine assemblies for heavy industry gain a motor suitable for modernisation work.
• Energy and auxiliary drives in manufacturing plants benefit from low-voltage connection and efficient operation.
