The three-phase 3LC-180M-2 electric motor is designed to bring the efficiency and value of the 3LC-180M-2 model into everyday operation in light and medium industry. This 3000 rpm electric motor with an output of 22 kW and a rated speed of 2960 rpm fits drives where smooth starting, stable running and sensible network loading during long shifts are important.
3000 rpm electric motor for smooth production-line operation
IE3 efficiency class supports lower energy consumption under normal load, which is valuable in operations working in repeated cycles that want to avoid unnecessary energy costs. A power factor of 0.89 helps keep the drive in a sensible electrical balance, including in systems controlled by a frequency converter or directly from the mains. Industrial automation also requires predictable response, and that is a practical advantage of this solution.
For integrators and OEM machine manufacturers, compatibility with a standard 400 V motor supply is also important, with a rated current of 38.5 A at △ 400V. At Y 690V, the rated current is 22.32 A, making design easier in applications with different supply configurations. LRT/RLT 2 and BDT/RLT 2.3 provide useful data for assessing starting and breakdown behaviour in systems with higher inertia.
Robust cast-iron frame for smaller technological units
The robust cast-iron frame with reinforced cast-iron bearing shields and reinforced cast-iron feet helps absorb loads caused by frequent starts, vibration and prolonged operation on a production line. A packaging weight of 184 kg and rotor inertia of 0.089 kg/m² are values that support stable operation in machines where accurate power transmission matters.
ISO certificates are part of the standard supply verification process for many purchasing and technical departments, particularly when the motor is intended for a line where safety, repeatability and transparent servicing requirements matter. A noise level of 83 dB(A) remains within a range that can be managed in an industrial environment without unnecessarily complicating the acoustic design of the hall.
Dimensions and bearings for installation without delays
Installation discipline also matters in restricted machine enclosures and compact assemblies. Packaging dimensions of 802*447*576 mm simplify logistics and storage, while cable glands 2-M40X1.5 support practical cable routing in confined spaces. Both the DE 6311-C3 bearing and NDE 6311-C3 bearing are selected for longer service under stable axial and radial loads.
8 applications for production and technological use
In practice, this three-phase electric motor is particularly suitable for the following assemblies:
- belt-conveyor drives in packaging lines,
- mixers for chemical and food dosing systems,
- process-water pumps in treatment plants,
- fans and extraction units in paint shops,
- compressor units in smaller workshop compressed-air systems,
- crushers and feeders in recycling lines,
- winding and unwinding stands in material processing,
- grinding and cutting units in OEM machines.
Operating performance for everyday loads
A 3000 rpm electric motor designed this way makes sense where fast operation, repeatable starting and long service life are required together. If you need a motor for an assembly line, machine or smaller technological unit, order the 3LC-180M-2 in good time to shorten downtime and maintain smooth production.
