Electric motor 22 kW, 2965 rpm, 400 V / 690 V, 4LC-180M-2 LV

Compared with IE2 or IE3 class solutions, this motor offers greater scope for energy savings as well as lower thermal stress in long-term operation. The 4LC-180M-2 model with an output of 22 kW and a speed range of 2900-3000 rpm is designed with emphasis on advanced materials, precise rotor processing and sophisticated windings so that it can operate reliably in applications where stability, efficiency and predictable load are decisive. In practice, this is an IE4 electric motor that helps reduce operating losses during long duty cycles.

For operators of pumps, fans, compressors and large machines, not only output is important, but also starting behaviour. This three-phase motor 400/690 V has a rated current of 38 A when connected in △ 400 V and 22.03 A when connected in Y 690 V, which makes integration into low-voltage infrastructure easier. The starting torque Tst/Tn 2 and breakdown torque Tmax/Tn 2.3 provide reserve for starting under load, while the starting current Ist/In 9.5 must be taken into account when designing starting and protection. The power factor 0.89 supports economical operation and efficiency of 94 percent is especially important where the motor runs for most of the day.

Operation in the speed class 2900-3000 rpm for stable performance

The rated speed of 2965 rpm naturally fits into the segment where high productivity and precise holding of the operating point are expected. This solution is suitable for high-speed applications where smooth operation without unnecessary fluctuations and with a good reserve for dynamic load is required. At a noise level of 83 dB(A), it is advisable to allow for installation in a plant room or to use structural noise reduction according to the nature of the operation.

Construction, bearings and accessories increasing service reliability

The all-cast-iron design combined with the IEC frame 180 mm provides robust mounting for industrial use and better handling of vibrations. Bearing DE 6311-C3 and bearing NDE 6311-C3 are selected for reliable operation under load, while the rotor inertia of 0.1 kg*m² supports predictable response during starting. The package also includes 3 PTC thermistors, which help with thermal monitoring of the motor in more sensitive applications.

Dimensions and connection for rapid integration into the technology

Cable entries 2-M40X1.5 make connection easier in standard industrial assemblies and the packaging dimensions of 802*447*576 mm together with a packaging weight of 184 kg are important when planning handling, storage and installation. This motor is a suitable choice for drives where a reliable purchase, long service life and a sensible operating reserve are required. If you need a motor for new equipment or as a replacement in an existing line, request a quotation and check suitability for the specific operating conditions.
