A robust cast-iron frame gives this four-pole electric motor a solid foundation for everyday operation in light and medium industry. The 3LC-180M-4 model delivers an ideal balance between purchase price and energy savings, which is decisive in drives for production lines, conveyors and processing equipment.
The design with reinforced bearing shields and cast-iron feet increases resistance to vibration, imperfect alignment and long-term loading in cyclic operation. This is exactly why this three-phase electric motor performs well wherever stable starting, precise speed maintenance and minimal service intervention are required from the drive.
Four-pole electric motor for stable operation of production technologies
A rated speed of 1475 rpm provides a balanced compromise between torque and speed, which helps in drives for agitators, pumps and smaller compressor assemblies. A rated current of 33.5 A at △ 400 V and 19.42 A at Y 690 V simplifies switchgear design and the sizing of protection in machine assemblies.
In practice, this is appreciated by OEM manufacturers as well as maintenance teams that need a motor without unnecessary compromises during starting and loading. A starting torque ratio of 2 and breakdown torque ratio of 2.3 support reliable acceleration in operations where equipment starts under load. A starting current ratio of 7.8 also helps estimate behaviour at switch-on more accurately.
IEC frame size 180 mm for easy integration into machines
IEC frame size 180 mm facilitates integration into existing frames, gearboxes and pumping units. Cable glands 2-M40X1.5 simplify connection in switchgear and make installation easier in compact technological units.
- Production conveyor in a packaging line.
- Screw conveyor in plastics granulation.
- Centrifugal pump in a water-treatment plant.
- Agitator in a food-processing tank.
- Air-handling fan for factory-hall ventilation.
- Pressing unit in light engineering production.
- Operating drive for a smaller compressor unit.
IE3 electric motor reduces energy demand under stable load
IE3 efficiency class supports energy efficiency that becomes apparent during longer duty cycles as well as repeated daily use. Super high efficiency is particularly beneficial in facilities where the motor runs for much of the shift and every percentage difference in losses affects costs.
Efficiency of 92.6% and a power factor of 0.86 help make better use of supplied energy in typical industrial applications. A noise level of 76 dB(A) is suitable for production areas where workplace acoustic load is also monitored. Rotor inertia of 0.168 kg/m² supports predictable behaviour during starting and stopping.
Proven motor for thousands of industrial installations
This IE3 electric motor builds on a solution proven in thousands of industrial installations, from smaller technological units to serial OEM assemblies. The DE bearing 6311-C3 and NDE bearing 6311-C3 contribute to long-term operational stability, which is important in continuous production as well as frequent starting.
A packaged weight of 182 kg and package dimensions of 802*447*576 mm simplify logistics when shipping to a site or assembly warehouse. The 3LC-180M-4 model is ready for applications where reliable operation, straightforward integration and controlled operating costs are expected. Take advantage of the offer and equip your drive with a motor that supports energy efficiency and long-term operational reliability.
