The design of the three-phase electric motor 3LC-180L-4 is intended to deliver the efficiency and value of the 3LC-180L-4 model in normal industrial operation without unnecessary demands on the operator. In practice, it is a 1500 rpm electric motor suited to lines where stable starting, reasonable consumption and smooth power transmission throughout every shift are important.
1500 rpm electric motor for smooth operation of production assemblies
A rated speed of 1475 rpm helps maintain consistent operation of conveyors, pumps and smaller processing machines. When supplied as a 400 V electric motor, it performs well in assemblies that require a balanced relationship between torque and operating consumption. With a power factor of 0.86 and efficiency of 93%, the motor is suitable for applications where energy costs are also monitored.
IE3 efficiency class for lower operating costs
IE3 efficiency class supports more economical operation in light and medium industry as well as industrial automation environments. In series operation, the difference is particularly noticeable on machines that run for long hours each day and require balanced performance without frequent intervention. In OEM solutions, it provides a practical basis for designing a drive with a reasonable power reserve.
A starting torque ratio of 2 and starting current ratio of 7.8 are suitable for mechanisms that need reliable starting without excessive stress on the power network. A breakdown torque ratio of 2.3 supports use where the drive may operate under less predictable loads. ISO certificates also strengthen confidence when deploying the motor in projects where repeatable supply quality is monitored.
Robust cast-iron frame for machines under daily load
A robust cast-iron frame is beneficial in assemblies that operate continuously and transmit vibration from the machine to the motor frame. Reinforced cast-iron bearing shields and reinforced cast-iron feet help maintain mounting precision even during long-term operation. 6311-C3 bearings on both the DE and NDE sides support reliability in typical industrial installations.
A noise level of 76 dB(A) suits equipment where not only performance but also the operator’s working environment is monitored. A packaged weight of 216 kg and package dimensions of 872*447*576 mm simplify handling planning in the workshop and during integration into new projects.
Solution for OEM machines and smaller technological units
This three-phase electric motor is suitable for lines where precise connection, straightforward installation and stable operation throughout the shift are expected. Cable glands 2-M40X1.5 simplify electrical installation, while rotor inertia of 0.207 kg/m² helps when designing acceleration and stopping. Thanks to a shaft height of 180 mm, the motor is also suitable for compact machine frames.
It is specifically suitable for the following applications:
- Main drive of a belt conveyor in a packaging line.
- Screw-conveyor drive for bulk materials.
- Pumping unit for process water in an industrial facility.
- Fan assembly for extracting production dust.
- Agitator for process tanks in the food pre-processing section.
- Pressing unit in a smaller processing machine.
- Granulation line in a recycling facility.
- Cutting machine for profile material.
- Briquetting press for processing workshop waste.
- Continuous feeder for a filling station.
- Drum-separator drive in sorting technology.
If you need a 1500 rpm electric motor for a machine that must operate reliably and with reasonable running costs, order the 3LC-180L-4 without delay. In practice, availability can change quickly for projects moving into production without delay.
