A rated speed of 2970 rpm and an output of 45 kW make the 3LC-225M-2 a solution for drives that require stable torque and efficiency in continuous operation. This two-pole electric motor delivers particular value where long working cycles, accurate acceleration and a low level of unplanned downtime are expected.
Two-pole electric motor for precise starting and stable load
A rated current of 76.8 A at △ 400 V and 44.52 A at Y 690 V allows suitable use in standard industrial power systems. A starting torque ratio of 2 and breakdown torque ratio of 2.3 help when starting equipment with a higher shaft load. The starting current ratio of 7.7 is important when designing starting systems where protection sizing and the supply branch must both be considered.
Robust cast-iron frame for workshop and production use
The robust cast-iron frame is designed for operation where mechanical durability and mounting stability are decisive. Reinforced cast-iron bearing shields and reinforced cast-iron feet increase resistance when mounted on a machine frame and during long-term operation with vibration. A noise level of 86 dB(A) remains within a range that can be considered during workplace design without unnecessary compromise in robustness.
Bearing arrangement for longer service intervals
DE bearing 6313-C3 and NDE bearing 6313-C3 support stable operation under loads suitable for light and medium industry. Rotor inertia of 0.334 kg/m² helps when designing the starting process and selecting the connection to a gearbox or other driven component. Cable glands 2-M50X1.5 simplify connection in switchboards and OEM assemblies.
IE3 efficiency class reduces losses in everyday operation
IE3 efficiency class means Super High Efficiency and translates into lower energy consumption during long daily operating periods. An efficiency of 94% and a power factor of 0.9 support energy-efficient operation even in applications where the motor runs in a steady state. This is valuable when an asynchronous electric motor is integrated into lines with repeated starting and stable loads.
This series of asynchronous electric motors is used in conveyor belts for packaging lines, screw compressors, process-water pumps, extraction-system fans, mixers in food production, metal grinders, saw units, mixing units for chemical dosing, granulation lines, smaller extruders and winding drives in textile production. These applications place emphasis on repeatable torque transfer, thermal reserve and service accessibility.
Packaging dimensions and handling during installation
A packaging weight of 342 kg and packaging dimensions of 1012*542*596 mm are important for goods receipt, storage and installation. In practice, they simplify planning of lifting equipment in the workshop and logistics to production units. More than 15 years of experience with industrial drives is reflected in how this asynchronous electric motor is assessed both when selecting a replacement and when designing a new OEM machine.
Two-pole electric motor for OEM machines and technological units
In light and medium industry, a two-pole electric motor is used where compact dimensions, higher speed and a requirement for long-term operation come together. The 3LC PRO model in the 3LC-225M-2 version fits assemblies where existing mounting, shaft coupling and electrical connection must be matched precisely without changing the production logic. This approach saves time both when integrating new lines and when replacing an older drive.
When designing the system, it is useful to consider that the motor operates as an IE3 electric motor with an emphasis on efficiency and operating stability. If you are preparing a drive replacement, order the 3LC-225M-2 in good time so it is available without delays during installation and production start-up.
