A robust cast-iron frame gives this drive a solid foundation for long-term operation in light and medium industry. The 3LC-180L-6 model delivers an ideal balance between purchase price and energy savings, while as a six-pole electric motor with a power output of 15 kW it fits applications where stable torque, sensible speed and low maintenance requirements are important.
The construction with cast-iron feet and reinforced bearing shields increases durability under continuous load, vibration and frequent starts. This IE3 electric motor is designed to reduce energy losses in everyday production while maintaining consistent operation in machines that run in long duty cycles. Thousands of industrial installations confirm that it is suitable for repeated integration into OEM assemblies as well as modernisation of existing lines.
Thanks to a rated speed of 980 rpm, the motor performs well wherever balanced torque transmission without unnecessarily aggressive acceleration is required. The three-phase electric motor operates with a 400/690 V supply, simplifying switchgear and connection design in industrial units. IE3 efficiency class also supports energy-efficient operation under long-term load, which is particularly valuable in continuous service.
Six-pole electric motor for balanced operation
For applications requiring smooth starting and stable speed, this drive is suitable for:
- screw conveyors in packaging lines,
- belt conveyors in assembly halls,
- agitators in chemical production,
- pumping units for process water,
- fans for air-handling units,
- granulators in plastics processing,
- crushers in recycling operations,
- lower-power compressor stations,
- worm feeders,
- mills for fine grinding of raw materials,
- textile winding and unwinding machines.
Cast-iron frame for rigidity, lower vibration and longer service life
The cast-iron frame helps maintain mounting precision and reduces sensitivity to mechanical stress during operation. This is important in machines where the motor is mounted on a frame, base skid or compact unit assembly. Combined with 6311-C3 bearings on both the DE and NDE sides, it creates a solution prepared for long operating intervals and predictable servicing.
Energy efficiency reflected in operating costs
An IE3 electric motor with efficiency of 91.2% and a power factor of 0.81 helps keep consumption under control under normal load. Industrial operations also benefit from a noise level of 73 dB(A), supporting better working conditions near the machine. Rotor inertia of 0.250 kg/m² is also useful when designing the assembly and accounting for acceleration and coast-down dynamics.
Installation details for OEM machines and smaller technological units
When integrating the motor into equipment, cable glands 2-M40X1.5 simplify routing of power conductors in compact spaces. A packaged weight of 211 kg and package dimensions of 872*447*576 mm simplify logistics and installation planning in the workshop or on the production line. Rated currents of 29.3 A at △ 400V and 16.99 A at Y 690V are also important for unit design and support correct sizing of protection and control.
To provide power reserve during starting, the motor offers ratios of LRT/RLT 2, BDT/RLT 2.1 and LRA/RLA 7.3. 3LC PRO therefore provides a reliable basis for conveyors, agitators, pumps and technological units requiring repeatable operation and technical discipline. Take advantage of the offer for a motor that combines robust construction with energy savings and stability for everyday use.
