Electric motor 18,5 kW, 2960 rpm, 400 V / 690 V, 4LC-160L-2 LV

For pumps, fans, compressors and even heavier machines, the 4LC-160L-2 with an output of 18.5 kW and speeds in the range 2900-3000 rpm brings direct operational benefits: higher efficiency, lower losses and long-term stability when supplied at 400 V / 690 V. In practice, this means lower energy costs while retaining a reserve for reliable starting and smooth operation in low-voltage applications. This low-voltage asynchronous electric motor is designed to help reduce operating expenses without unnecessary compromises in robustness.

Economical operation under high load

In the industrial drive segment, the decision is based not only on rated output, but also on how the motor handles real load throughout the entire shift. The 4LC-160L-2 model belongs among energy-saving industrial motors with an efficiency of 93.7 % and a power factor of 0.89, which helps to reduce waste heat and make better use of the supplied electrical energy. In long-term use, this improves the cost balance and at the same time makes drive design easier in systems where every percentage of consumption is monitored.

• Rated current delta 400 V is 32 A, which simplifies the sizing of protection and supply components.
• Rated current star 690 V is 18.55 A, so the motor can also be adapted for higher-voltage connection.
• Rated speed 2960 rpm is suitable for drives that need quick response and stable flow.
• The starting torque ratio Tst/Tn is 2, so the motor provides a usable starting reserve.
• The breakdown torque ratio Tmax/Tn is 2.3, which supports handling short-term overloads.
• The starting current ratio Ist/In is 9.5, so it is advisable to allow for appropriate switching and protection.
• Noise level 81 dB(A) is suitable for applications where the acoustic load of the workplace is also monitored.

The design increases reliability in continuous operation

Experienced operators particularly appreciate the fact that the motor maintains its parameters even with repeated starts and long cycles. The rotor inertia of 0.1 kg*m² supports predictable starting behaviour, and the 6309-2RZC3 bearings on the DE and NDE sides are selected for long service life under industrial load. The added 3 PTC thermistors help monitor the thermal condition of the winding, which is especially practical in applications where there are several starts in succession or changing process conditions.

Overview of mechanical and service details

• The packed weight is 156 kg, which is important when planning handling and installation.
• The packed dimensions 822*407*566 mm make logistics and storage easier.
• The 2-M40X1.5 cable glands allow practical and clear cable connection.

Use in demanding industrial operations

For pump and fan drives, stable speed provides precisely the operation that process control needs, while for compressors the ability to deliver power continuously without significant fluctuation is crucial. In engineering operations you will also appreciate that the IE4 electric motor reduces energy demand while maintaining a high level of operational discipline. Thanks to this profile, it is a solution for companies that monitor return on investment, technology availability and easier integration into existing infrastructure.

• Pumps with constant or variable flow.
• Fans for air handling, extraction and cooling.
• Compressors with an emphasis on reliable starting and stable pressure.
• Conveyor and handling mechanisms.
• Machine units in light and medium-heavy production.
• Production lines requiring continuous operation.
• Circulation systems in industrial installations.
• Pumping stations and pressure systems.
• Air systems in service buildings.
• Machines with frequent starts and load changes.
• Operations monitoring energy efficiency.
• Modernised drive assemblies in low-voltage environments.
• Standby drives in technologies where quick restoration of operation is important.

Parameters supporting easier integration into drives

When designing the connection, it is important that the motor has predictable electrical and mechanical characteristics, which makes it easier to select protection devices, contactors and the starting method. Rated values, bearing arrangement and thermal protection form a practical basis for integrators who need to combine reliability with accessible service. VYBO Electric relies on in-house development and premium materials for this type of drive, which is particularly noticeable in the professional range in longer service life and stable build quality.
