The 3LC-200L2-2 offers an excellent balance between purchase price and energy savings and is designed as a 2-pole electric motor for operations where stable starting, good efficiency and long-term spare-parts availability are important. In light and medium industry, this electric motor is particularly suitable where the drive is connected to pumps, fans, conveyors and other machines with regular loads. The manufacturer draws on years of experience, reflected in a design suitable for everyday industrial practice as well as OEM drive technology.
IE3 efficiency class – Super High Efficiency supports lower energy consumption during prolonged operation and is particularly beneficial in shift-based applications where the motor is used repeatedly throughout the day.
A robust cast-iron frame provides firm support for the bearing arrangement and better resistance to vibration in confined technological units. Reinforced cast-iron bearing shields and reinforced cast-iron feet help maintain accurate motor positioning even during frequent starting or installation in machine frames where a rigid base and limited service space are expected. The design is therefore suitable for operations that need a reliable asynchronous drive without unnecessary downtime.
2-pole electric motor for machines requiring fast response
A rated speed of 2970 rpm is suitable for applications where the mechanical system must accelerate quickly and run smoothly without unnecessary transmission overload. Rated current of 64 A at △ 400V and 37.1 A at Y 690V helps with switchboard and protection design in standard drive projects. A power factor of 0.89 supports sensible use of electrical energy under stable load.
Starting performance remains important in practice, including repeated operating cycles. A starting torque ratio of 2 and breakdown torque ratio of 2.3 help in applications where the drive must pick up quickly and then maintain its operating point without fluctuations. A starting current ratio of 7.6 is important when sizing the entire installation, particularly in smaller technological units where available input power is monitored.
Cast-iron construction for everyday industrial loads
In light and medium industry, installation often requires attention to alignment accuracy, vibration and maintenance access. A robust frame and mass stability are therefore important. A packaging weight of 263 kg reflects the substantial construction, which provides a stable base when mounted on the machine. Rotor inertia of 0.190 kg/m² helps when designing cyclic movements where acceleration and coast-down behaviour must be considered.
Packaging dimensions of 862*492*656 mm simplify transport planning and warehouse handling. Cable glands 2-M50X1.5 provide practical space for connection in industrial assemblies where safe cable routing and clear installation are priorities. DE bearing 6312-C3 and NDE bearing 6312-C3 complete a concept designed for long-term loading in electric drives.
Asynchronous electric motor for OEM machines and smaller units
This asynchronous electric motor is suitable for OEM machines where the designer needs to combine performance with reasonable operating requirements. In smaller technological units, it performs well in conveyor modules, mixing units and compact lines that need to run reliably without complicated modifications. It can therefore be used as a versatile drive building block when designing machinery.
Its use in drive technology also makes sense where repeated starting, short running intervals and easy maintenance are required. This makes it suitable for assemblies that must remain service-accessible while also withstanding long-term operation.
Specific industrial applications for 3LC PRO
The following are typical industrial applications for this motor:
- Horizontal belt conveyor for a packaging line.
- Screw conveyor for bulk materials in a mixing plant.
- Centrifugal process-water pump in a treatment plant.
- Radial fan for extraction from a production hall.
- Aeration compressor in a smaller wastewater treatment plant.
- Roller conveyor in an assembly line.
- Mixer for industrial tanks and storage vessels.
- Packaging-material crusher in a recycling line.
- Granulator for plastics processing.
- Pressing unit in a smaller production cell.
- Unwinding and winding stand for films and strips.
- Grinding unit in a metalworking workshop.
- Feeding mechanism for automated packaging machines.
Operation built around efficiency and service logic
In long-term use, performance is not the only factor that matters; it is also important how the motor fits into servicing, installation and the energy balance of the complete line. IE3 efficiency class supports economical operation and helps reduce operating costs without requiring a complete redesign of the drive solution. This is practical both when modernising older equipment and in new production where a sensible budget and stable operation are required.
If you need a motor for equipment that must run regularly without unnecessary compromises, the 3LC-200L2-2 is a functional solution for production environments. Take advantage of the offer and choose a drive that supports long-term reliability and lower operating losses.
