Electric motor 160 kW, 1490 rpm, 400 V / 690 V, 4LC-315L1-4 LV

When a production drive loses stability, downtime, consumption and maintenance costs rise. The 4LC-315L1-4 model with an output of 160 kW is designed for operation in the speed class 1400-1500 rpm, where a precise balance between efficiency, torque and reliable starting is important. The design uses advanced materials and sophisticated windings, so it helps to maintain stable performance even under long-term load in industrial conditions.

IE4 efficiency brings lower losses in continuous operation

This IE4 electric motor is suitable for operations that want to reduce energy intensity without compromising robustness. With an efficiency of 96.6 % and a power factor of 0.9, it can make better use of the supplied energy, which is important in long production cycles, pumps, fans and conveying technology too. The 315 mm frame size provides a solid mechanical reserve and makes it easier to integrate into modernised assemblies with low-voltage infrastructure.

Drive parameters support safe starting and stable operation

The starting torque ratio Tst/Tn 1.8 and the maximum torque ratio Tmax/Tn 2.2 show that the motor is ready to handle standard operating peaks during start-up and load changes. The starting current ratio Ist/In 8.5 is important when designing the starting method and sizing supply components. The rated current in delta connection at 400 V is 269 A and in star connection at 690 V it is 156 A, giving technology suppliers more scope for a more precise choice of start-up and protection.

Mechanical design increases readiness for long industrial operation

For drives for light and heavy industry, the combination of durability and service predictability is crucial. The DE 6319-C3 bearing and the NDE 6319-C3 bearing support smooth operation and 3 PTC thermistors help monitor the thermal load of the winding. The rotor inertia of 4.7 kg*m² contributes to suitable dynamics during run-up and smaller fluctuations during operation. Noise level 88 dB(A) should be taken into account when designing the workplace already at the project stage.

Dimensions and connection make installation into existing technologies easier

The packaging dimensions of 1412*727*1026 mm and the packaging weight of 1088 kg confirm that this is a solution for heavier industrial use with an emphasis on precise logistics and handling. The 2-M63X1.5 cable entries make connection easier in control cabinet and machine assemblies, and when designing it is practical to allow for a clearly defined installation space. This design is suitable where a drive is being modernised without unnecessary compromises in installation.

Overview of the main technical benefits for designers

• Rated speed of 1490 rpm is suitable for standard industrial operations in the medium speed class.
• Output of 160 kW provides sufficient reserve for more demanding process lines.
• Efficiency of 96.6 % helps reduce operating losses during long running periods.
• Power factor 0.9 supports more efficient use of electrical energy in the system.
• Accessories in the form of 3 PTC thermistors increase control over the thermal condition of the motor.
• 6319-C3 bearings on both sides unify service requirements.

Use in modernisation projects and stable operation

The motor is suitable for conveyor systems, pumps, fans, compressor sets, mixers, process units, production lines and auxiliary units where long-term load capacity and precise drive control are expected. In practice, it will prove itself when replacing older units, when reducing energy intensity and also in projects that need a reliable 4-pole electric motor for continuous production. VYBO Electric builds on many years of experience in the development of industrial electric motors, so this model combines premium materials, in-house design solutions and confidence for a responsible purchase.
