Electric motor 110 kW, 2980 rpm, 400 V / 690 V, 4LC-315S-2 LV

For production lines, pumps, fans and compressor sets, the 4LC-315S-2 with an output of 110 kW brings a practical benefit in the form of high energy efficiency and stable operation in the range of 2900-3000 rpm. In this speed class, the IE4 design can noticeably reduce operating losses compared with IE3, which is reflected in long production cycles where every kilowatt hour matters. This is a three-phase motor designed for low-voltage networks of 400 V / 690 V and for operations that need reliable performance without unnecessary downtime.

Efficiency and stability in continuous operation in the range of 2900-3000 rpm

The motor design uses principles typical for the segment marked 2-pole electric motor, that is, for solutions with high speeds and good dynamic behaviour. An efficiency of 96 % and a power factor of 0.89 help to reduce grid load and energy costs in applications with long daily duty. For maintenance engineers, the starting profile is also important: the Tst/Tn ratio is 1.8, the Tmax/Tn ratio reaches 2.3 and the Ist/In ratio is 8.5, which makes it easier to assess motor behaviour during start-up and load peaks. In practice, this makes it easier to design switchboards, soft starters and frequency converters in line with operational requirements.

Construction features that simplify integration into production

The motor has a shaft height of 315 mm, a packing weight of 843 kg and packing dimensions of 1302*727*1026 mm, so it can be planned into installation and logistics without unexpected complications. The 2-M63X1.5 cable entries provide space for connecting power cables in an industrial environment. The bearing arrangement DE 6317-C3 and NDE 6317-C3 supports stable operation under higher mechanical load, and 3 PTC thermistors increase safety under thermal stress. The rotor inertia of 1.5 kg*m² is suitable for applications where a predictable starting characteristic and control of acceleration are important.

Operating data for more precise drive design

The rated speed of 2980 rpm and the noise level of 92 dB(A) should be taken into account when placing the motor in the plant and when designing enclosure. The high efficiency of 96 % is suitable for modernisations where not only output is monitored, but also the overall TCO of the drive. For the technical department, it is valuable that VYBO Electric works with in-house development and premium materials, while also providing expert technical advice when selecting a replacement for an existing drive.

Industrial applications of the electric motor

The motor is suitable for operations where a combination of higher output, precise deployment and resistance to long-term load is required. Thanks to its rated parameters, it can be used with direct-drive and geared-drive equipment.

• Pump stations with continuous operation.
• Large-capacity ventilation and air-handling units.
• Compressor units in industrial sites.
• Crushers and sorting technologies in raw material processing.
• Grinding mills and mixing equipment in processing lines.
• Transport and conveyor systems with higher load.
• Modernised production lines with 400 V / 690 V supply.

Compared with standard solutions, this design offers room for energy savings and greater stability in operation where long running and repeated starting are expected. If you need to verify compatibility with existing equipment, check whether the motor is suitable for your application. The electric motor is in stock and ready for rapid deployment in your operation.
