Electric motor 30 kW, 990 rpm, 400 V / 690 V, 4LC-225M-6 LV

When selecting a motor for pumps, fans, compressors and large machines, it is worth focusing on operational efficiency, load stability and dependable service support. The 4LC-225M-6 model with an output of 30 kW and a speed class of 900-1000 rpm helps to reduce operating costs where long-term efficiency and reliable operation in low-voltage infrastructure are decisive. In practice, this is a low-voltage asynchronous electric motor, suitable both for an energy-saving industrial motor system and for low-speed industrial applications with an emphasis on even power transmission.

High efficiency reduces costs during long operating cycles

An efficiency of 94.2 % and a power factor of 0.82 support more economical energy consumption during continuous operation. When connected to 400 V, the motor has a rated current of 55.4 A in delta connection, and at 690 V it reaches 32.1 A in star connection, which makes it easier to select according to the network and technology. The starting current with an Ist/In ratio of 8.3 must be taken into account when sizing protection, the switchboard and starting equipment.

Mechanical construction supports long service life in demanding environments

The all cast iron design with a centre height of 225 mm provides a robust base for higher loads and better vibration damping. A package weight of 378 kg together with a rotor inertia of 0.6 kg*m² creates a stable foundation for drives that must operate without fluctuations. 6313-C3 bearings on both the DE and NDE sides support operation in conditions where precise mounting and resistance to long-term stress are required.

Operating parameters help with precise drive design

The rated starting torque ratio Tst/Tn of 2 and the pull-out torque ratio Tmax/Tn of 2.1 give a clear picture of motor behaviour at start-up and during short-term overload. Noise level of 76 dB(A) is important in installations where the motor is located close to the operator or within production units with stricter acoustic limits. Cable glands 2-M50X1.5 are used for connection, simplifying technical installation and cable routing.

Factory equipment simplifies integration into the control system

The PTC winding protection accessory helps to protect the motor against thermal overload and supports safer operation under fluctuating load. This makes the motor easier to integrate into assemblies where winding condition is monitored and where a rapid response to temperature changes is important. This approach will be particularly appreciated by operations that want to limit unplanned downtime while maintaining simple operational control.
