2-pole electric motor for savings in continuous operation
The 3LC PRO 3LC-315L2-2 is designed for operations that monitor both energy savings and long-term drive value. This 2-pole electric motor with an output of 200 kW and a speed of 2980 rpm delivers stable performance to production lines, pumps and compressor assemblies where smooth starting and balanced operation are expected. For medium-sized companies, large factories, engineers and designers, predictable operation and a low risk of unplanned intervention are particularly important.
IE3 efficiency class – Super High Efficiency supports lower consumption under normal load and reduces pressure on operating costs during long shifts. In practice, this is valuable for any drive technology running in multi-shift production that needs to maintain performance without unnecessary energy losses. Rated current of 331 A at △ 400V and 191.88 A at Y 690V allows more flexible integration into existing power systems. A power factor of 0.91 supports economical use of the network, and an efficiency of 95.8% is beneficial where monthly operating costs are closely monitored.
Cast-iron frame for demanding production conditions
The robust cast-iron frame – reinforced cast-iron bearing shields and reinforced cast-iron feet gives the motor the rigidity appreciated by installers and service technicians in environments with elevated vibration. A packaging weight of 1087 kg and packaging dimensions of 1412×727×1026 mm reflect a robust construction suitable for industrial assemblies where the motor must be supported on a stable foundation. Rotor inertia of 2.654 kg/m² helps stabilise operation in applications with regular starting and load changes. DE bearing 6317-C3 and NDE bearing 6317-C3 support longer service intervals and accurate rotor guidance in demanding operation.
ISO certificates are a practical indication of manufacturing discipline, process control and repeatable supply during purchasing. In technical procurement, this framework matters because it reduces uncertainty when installing the motor in a line or replacing an existing unit. A noise level of 92 dB(A) should be considered when designing the machine room, especially if the motor is integrated into compact spaces with limited acoustic separation.
2-pole electric motor for drives that must not slow production
When designing a drive, this three-phase electric motor is suitable wherever high rotational speed and stable torque transmission to the driven machine are required. Starting torque ratio LRT/RLT 1.8 and breakdown torque ratio BDT/RLT 2.2 help start heavier mechanisms without unnecessary stress on the network. Starting current ratio LRA/RLA 7.2 should be considered when sizing protection and the switchboard, particularly with frequency-converter supply or direct-on-line starting.
In practice, a 400 V electric motor is used in plants where a 400/690 V network forms part of the standard infrastructure. This makes integration into existing technological units easier and simplifies the design of new lines. A three-phase electric motor of this output is suitable for applications requiring long-term operation without parameter fluctuation and without frequent operator intervention.
Specific industrial use in 11 applications

A choice for technicians who calculate operating costs
For engineers and designers, the key advantage is that this 2-pole electric motor allows precise design of gearing, mounting and power supply. When modernising a line or replacing an older unit, it helps shorten installation time and maintain compatibility with industrial requirements. Combined with high efficiency, robust cast-iron construction and a proven manufacturing background, it is a solution that meets the demands of both standard and heavier drive technology.
