Electric motor 30 kW, 1480 rpm, 400 V / 690 V, 4LC-200L-4 LV

In the operation of pumps, fans or compressors, energy loss, thermal reserve and reliability during long shifts are decisive. The 4LC-200L-4 model with an output of 30 kW is designed for the 1400-1500 rpm speed class, where it can maintain stable performance while also reducing unnecessary losses that commonly arise with less energy-efficient motors. In practice, this means that the three-phase motor in IE4 class can reduce the energy load by approximately 15 % to 20 % compared with IE3, depending on the nature of the operation, which is particularly noticeable in continuous duty.

The design with an IEC 200 mm frame makes it easier to integrate into existing assemblies while maintaining space for good cooling. The motor uses principles typical of super premium efficiency, namely advanced materials, sophisticated windings and optimised air gaps, which improve operational economy. As a 4-pole electric motor, it is suitable where a balanced compromise is required between torque, speed and efficiency in low-voltage infrastructure.

Operation in the 1400-1500 rpm range for stable industrial running

In this speed segment, the motor provides a rated speed of 1480 rpm, which is a practical value for both direct and reduced drives. The rated current at delta 400 V is 53.1 A and at star 690 V is 30.78 A, so the connection design can be adapted to the supply system and starting conditions. The power factor of 0.85 helps to keep the network load reasonable during long-term operation.

Technical features that support reliable performance

The motor achieves an efficiency of 94.9 % and a noise level of 76 dB(A), which is important when installed in a machine room or in a technological unit with higher acoustic requirements. The starting torque ratio Tst/Tn is 2, the breakdown torque ratio Tmax/Tn is 2.3 and the starting current ratio Ist/In is 9, so the unit is ready for normal load conditions during start-up and transient states. The rotor inertia of 0.3 kg*m² supports a predictable drive start-up.

Installation and service data for the maintenance technician

The DE bearing 6312-C3 and the NDE bearing 6312-C3 are selected for operation with an emphasis on longer service life and mechanical reserve. The 2-M50X1.5 cable entries make tidy connection easier, while the accessories in the form of 3 PTC thermistors provide effective thermal protection of the winding. The package weight of 279 kg and the package dimensions of 862*492*656 mm are important when planning handling, storage and installation in operation.
