Electric motor 15 kW, 980 rpm, 400 V / 690 V, 4LC-180L-6 LV

Motor 4LC-180L-6 with an output of 15 kW is designed for operations where stable torque, sensible electricity consumption and long-term return on investment are monitored. In the speed class 900-1000 rpm, it provides a suitable basis for pumps, fans, compressors and other machines with continuous load. As a low-voltage asynchronous electric motor, it helps reduce operating costs where reliability and efficiency in year-round operation matter.

Efficient operation in the IE4 efficiency class

The energy-saving industrial motor with IE4 efficiency class brings lower operating losses, which in businesses results in less heat, better use of electrical energy and more stable running during longer shifts. Motors at this efficiency level use advanced materials, sophisticated windings and optimised air gaps, so they can work more efficiently even under heavier load. In long-term use, this difference is one of the reasons why the investment pays back through energy savings.

Convenient connection into low-voltage infrastructure

The rated current delta 400 V is 28.8 A and the rated current star 690 V is 16.7 A, which makes control cabinet design and protection sizing easier depending on the connection and operating voltage. The power factor 0.8 supports balanced operation in networks where actual load and economy are monitored. For technicians, the starting current ratio Ist/In 8.5 is also important and must be taken into account when starting larger units and when coordinating with switching equipment.

Starting and pull-out behaviour for work with changing load

The starting torque ratio Tst/Tn 2 and the pull-out torque ratio Tmax/Tn 2.1 give the motor the ability to handle normal starts and short-term peaks in systems with variable resistance. In practice, this will be appreciated by operations with conveyor technology, air handling, pumping systems and compressor units, where smooth starting is required without unnecessary strain on the mechanics. The rated speed of 980 rpm also supports compatibility with applications that prefer a lower speed and higher torque effect.

Construction that supports long service life in industry

Most operating decisions depend on details, and that is why the motor offers bearing DE 6311-C3 and bearing NDE 6311-C3 for reliable rotor support in long-term use. The rotor inertia of 0.3 kg*m² helps predictable dynamic behaviour during starting and load changes. The noise level of 73 dB(A) is a value that will be used in practice by operations monitoring the working environment and operator comfort. Accessories in the form of 3 PTC thermistors increase control over the thermal condition of the winding and help protect the motor under abnormal load.

Connection and mechanical installation without unnecessary compromises

The frame size of 180 mm makes it easier to integrate into standard industrial assemblies, where not only performance but also spatial compatibility is addressed. The 2-M40X1.5 cable entries allow practical routing of leads and easier adaptation to installation requirements. The packaging dimensions of 872*447*576 mm and the packaging weight of 211 kg are important for logistics, storage and handling when receiving the machine. For service teams, the consistent technical identification of model 4LC-180L-6 is also important, as it simplifies the selection of spare parts and compliance checks during replacement.

Industrial applications of the electric motor

• Pumps benefit from stable operation when transporting liquids in both continuous and intermittent modes.
• Fans benefit from a balanced ratio of speed and efficiency during long-term operation.
• Compressors appreciate higher starting torque and reliable operation under load.
