The design of the 3LC-315L2-4 is intended to deliver operating savings and value for long-term use in higher-load drives. This 4-pole electric motor provides a solid basis for technologies where efficiency, starting torque and stability during repeated cycles are monitored. For medium-sized businesses and large factories, reliable performance means fewer disruptions to production and better predictability of operating costs.
IE3 efficiency class reduces consumption in continuous operation
IE3 efficiency class is particularly practical in this segment wherever the motor runs for long hours under steady load. Super high efficiency helps maintain a sensible balance between energy consumption and delivered mechanical power, which is appreciated in continuous and multi-shift production. In drives where every percentage point of loss is monitored, this creates room for better cost planning.
A rated power output of 200 kW and rated speed of 1485 rpm support use in applications that need stable torque and smooth starting. With a 400/690 V connection, the 400 V electric motor is suitable for standard industrial networks without unnecessary compromises in switchgear design. A rated current of 334 A at △ 400V and 193.62 A at Y 690V gives designers sufficient flexibility when sizing protection, cables and switching devices.
Robust cast-iron frame keeps the motor stable in demanding production lines
A robust cast-iron frame is important wherever the motor faces vibration, higher gearbox loads or long-term operation in contaminated environments. Reinforced cast-iron bearing shields and reinforced cast-iron feet increase assembly rigidity, reducing the transmission of unwanted stress into the mounting. For designers, this is an advantage when installing on frames, base plates and assemblies subject to higher dynamic loads.
Starting and braking parameters assist when designing drives with frequent starts. A starting torque ratio of 2, breakdown torque ratio of 2.2 and starting current ratio of 7.1 provide an important picture of how the motor behaves during acceleration and overload. Rotor inertia of 5.274 kg/m² also helps when assessing starting times in assemblies with greater mechanical coupling.
4-pole electric motor for pumps, conveyors and mixing technologies
This three-phase electric motor is suitable for operations requiring a combination of power, durability and straightforward service access. A noise level of 88 dB(A) is important when designing production halls and separating technological units in order to maintain safe working conditions. Cable glands 2-M63X1.5 simplify connection in assemblies with robust cable routing and industrial installation.
DE bearing 6319-C3 and NDE bearing 6319-C3 support long-term operation with correctly designed lubrication and precise alignment. ISO certificates within the manufacturing processes are particularly important for many companies because they simplify incoming inspection, internal audits and repeatable quality across recurring deliveries. In drive technology, this approach is practical because it reduces the risk of non-conformities during installation and subsequent servicing.
Specific industrial applications for 3LC PRO
The 3LC-315L2-4 has parameters well suited to demanding technologies with higher mechanical and thermal loads.
- Centrifugal cooling-water pump in a steelworks.
- Main extraction fan in a rolling-mill hall.
- Bulk-material conveyor in a cement plant.
- Belt conveyor for sorted aggregate in quarrying technology.
- Concrete-mixture mixer in a precast-production plant.
- Grain screw conveyor in a grain silo.
- Compressor unit for compressed air in an engineering workshop.
- Plastics extruder in polymer processing.
- Rotary screen in a waste-recycling facility.
- Press drive in a wood-processing line.
- Process-material crusher in a raw-material treatment plant.

Package dimensions of 1412*727*1026 mm and a packaged weight of 1214 kg are important for logistics, storage and planning handling within the plant. When selecting the motor for a specific line, it is also worth considering how it fits into the existing drive assembly, whether for new equipment or modernisation of an older machine. This 4-pole electric motor therefore makes sense wherever stable operation, long service life and reasonable operating costs are expected from a single component.
