Accurate operation, load reserve and long service life form the basis of the value offered by the 3LC-315L1-2. This 3000 rpm electric motor is designed to deliver the efficiency and value of the 3LC-315L1-2 model in continuous operation, where stable performance, reasonable operating costs and reliable starting under load are essential.
An output of 160 kW and a rated speed of 2980 rpm are well suited to drives that must operate without unnecessary interruptions or compromises in dynamics. For medium-sized companies, large factories, engineers and designers, it is important that a three-phase electric motor fits existing technology without creating unnecessary maintenance demands. This is why this IE3 electric motor is worthwhile in projects where not only output but also long-term operating behaviour is monitored.
3000 rpm electric motor for drives with smooth torque transfer
A rated speed of 2980 rpm supports smooth power transmission in applications requiring stable operating characteristics. A starting torque ratio of 1.8 and breakdown torque ratio of 2.3 provide useful reserve during starting and load changes. This is particularly practical where three-phase electric motors are used in assemblies with frequent starts, intermittent loads or starting through a gearbox.
Robust cast-iron frame for operation without unnecessary downtime
A robust cast-iron frame, reinforced cast-iron bearing shields and reinforced cast-iron feet increase durability during installation and long-term loading. This design helps absorb vibration and protect the bearing arrangement in environments where the motor is exposed to a demanding service regime. DE bearing 6317-C3 and NDE bearing 6317-C3 support reliable operation in applications running in regular production cycles.
In practice, this design performs well in cement conveyors, mixers, crushers, presses, fans, pumping stations, extrusion lines, compressors and rolling drives. In these applications, mechanical reliability and the ability to withstand long production shifts without unnecessary maintenance intervention are important.
IE3 efficiency for lower losses in everyday operation
IE3 efficiency class – Super High Efficiency supports more economical operation under normal load and helps reduce costs where the motor runs for a large part of the year. Rated current of 265 A at △ 400V and 153.62 A at Y 690V together with a power factor of 0.91 provide a sound basis for sensible sizing of the complete drive. For an IE3 electric motor, this is a practical advantage reflected in operation during long production cycles.
Construction ready for industrial deployment
A noise level of 92 dB(A) should be considered during machine and enclosure design, although it is a standard parameter for this power class in large industrial operations. Rotor inertia of 2.394 kg/m² helps when designing starting characteristics and coordinating with frequency converters, couplings or gearboxes. A packaging weight of 997 kg and packaging dimensions of 1412×727×1026 mm simplify planning for handling, storage and installation in production units.
The 3LC PRO model in this power category is backed by thousands of industrial installations, which is particularly useful when comparing service experience and repeated use in standard applications. The cable glands are listed without a specification, so their connection should be verified directly according to the project and mounting method.
If you need a drive for a pump, fan, conveyor, mixer, compressor, grinder, separator, extruder or process line, this 3000 rpm electric motor provides a solution for stable production. Order it in good time and secure reserve capacity for planned deployment without delays in preparing the technology.
