The 3LC-315M-2 with an output of 132 kW provides an excellent balance between purchase price and energy savings for operations where a 3000 rpm electric motor must keep pace with continuous production, pumps, ventilation systems and conveyor systems.
In designs for medium-sized companies and large factories, this asynchronous electric motor is suitable where stable torque, straightforward integration into the drive and disciplined long-term operation are decisive.
IE3 electric motor for lower operating losses under continuous load
IE3 efficiency class supports more economical operation during daily use on production lines, in pumping stations and in equipment running across multiple shifts. Industrial automation requires a motor that responds predictably without burdening the operating budget with unnecessary losses.
A rated speed of 2980 rpm helps maintain smooth acceleration of technological units and supports accurate connection to gearboxes, couplings and other drive components. A starting torque ratio of 1.8, breakdown torque ratio of 2.3 and starting current ratio of 7.1 are important when designing starts where both network conditions and the mechanical load of the equipment must be considered.
Robust cast-iron frame for vibration, impacts and long service life
The robust cast-iron frame with reinforced cast-iron bearing shields and reinforced cast-iron feet increases resistance to vibration and installation impacts. Engineers appreciate this approach when mounting the motor in heavier frames, steel structures and technological foundations where the rigidity of the entire drive unit must be verified.
DE bearing 6317-C3 and NDE bearing 6317-C3 are suitable for operations designed around long service intervals and careful monitoring of noise, since a sound level of 92 dB(A) is an important criterion when locating the machine in a hall.
Industrial applications for manufacturing, logistics and water management
Installation and handling requirements are also important when integrating the motor, because a packaging weight of 923 kg and packaging dimensions of 1412×727×1026 mm affect transport, storage and placement into the technology.

400/690 V for flexible switchboard connection
Rated current of 224 A at △ 400V and 129.86 A at Y 690V simplifies switchboard design, selection of protection and cable sizing. For designers, this means more accurate drive configuration in accordance with the voltage system and required starting method.
Rotor inertia of 2.111 kg/m² is important when calculating starting dynamics and assessing suitability for applications with frequent starts. More than 15 years of experience in industrial drives translates into selecting solutions that correspond to actual operating loads rather than catalogue values alone.
Speed and torque for stable performance in everyday operation
For production applications, the key point is that a 3000 rpm electric motor with a nominal speed of 2980 rpm can maintain a constant working pace even during long-term use in automated lines. This solution is suitable for operators who need a reliable drive core without unnecessary changes to the machine’s mechanical concept.
If you need a motor for new or modernised technology, choose the 3LC-315M-2 and obtain a drive that combines energy savings, structural rigidity and operating reliability in demanding industrial applications.
