Electric motor 45 kW, 2975 rpm, 400 V / 690 V, 4LC-225M-2 LV

Model 4LC-225M-2 with an output of 45 kW is intended for operations that require stable performance in the speed range 2900-3000 rpm and a secure connection to low-voltage infrastructure. In practice, it delivers a rated speed of 2975 rpm, a rated current of 76 A at △ 400 V or 44.06 A at Y 690 V, and an efficiency of 95 %, which is especially important for driving pumps, fans, compressors, and large machines. The construction uses elements that work together to reduce losses and help maintain performance even under long-term load.

Economical operation in IE4 efficiency class for stable operation of equipment

For demanding technological units, not only the rated value is decisive, but also the motor’s behaviour under actual load. This IE4 electric motor uses solutions typical of higher efficiency, namely higher quality materials, precisely designed windings, and controlled air gaps. The 225 mm frame provides a solid basis for installation in assemblies where long-term operation without unnecessary downtime is required.

Combined with a power factor of 0.89 and a noise level of 86 dB(A), the motor offers parameters suitable for technologies operating in both production and energy mode. The starting torque ratio Tst/Tn 2 and the breakdown torque ratio Tmax/Tn 2.3 help with starting and load changes. The starting current ratio Ist/In 9 must be taken into account when designing the switchboard and protection, which is a common requirement for high-power drives.

Design features that support long-term reliability

VYBO Electric builds on a long period of its own development and experience from industrial projects, which is reflected in the well-considered design of the details. The motor is fitted with DE 6313-C3 and NDE 6313-C3 bearings, which help ensure stable rotation in heavier duty operation. The rotor inertia of 0.3 kg*m² is beneficial for applications where smooth running and balanced dynamic behaviour are required.

For cabling, 2-M50X1.5 cable glands are prepared, which make it easier to route supply cables and contribute to a cleaner installation in machine assemblies. The equipment also includes 3 PTC thermistors, which support monitoring of the winding temperature. Such a solution is especially appreciated by operators who want to reduce the risk of overheating during long cycles or load fluctuations.

Industrial applications of the electric motor in demanding operation

The motor is suitable for assemblies where high operational reliability and repeated starting under load are required. It can be used in pumping stations, HVAC units, process fans, screw compressors, mixers, conveyor lines, pressing equipment, and in the main drives of production machines. In these segments, it is important to be able to operate in a stable mode without unnecessary energy losses and without excessive thermal stress.

In operations where every hour of downtime counts, this 2 pole electric motor offers a suitable combination of speed, efficiency, and mechanical reserve. The rated speed of 2975 rpm allows use in systems that require rapid power transmission while maintaining a precisely defined operating point. The packed weight of 342 kg and the package dimensions of 1012*542*596 mm are important for logistics, storage, and planning of installation at the site.

Speed range 2900-3000 rpm for drives with a precise operating point

In the range of 2900-3000 rpm, this motor is suitable wherever a higher speed is needed while maintaining reliable operation. This speed class is practical in applications where power is transferred directly to the working machine and any unnecessary loss between the motor and the technology is undesirable. As a result, this solution is suitable for operations looking for a balance between productivity, energy consumption, and long-term service reliability.
