Electric motor 22 kW, 985 rpm, 400 V / 690 V, 4LC-200L2-6 LV

In operations where electricity consumption and reliability under long-term load both matter, the 4LC-200L2-6 with an output of 22 kW helps reduce energy losses and maintain stable performance in the speed range of 900-1000 rpm. This three-phase motor is designed so that, when modernising drives for pumps, fans, compressors and large machines, it delivers noticeably more efficient operation than standard solutions, while the IE4 design typically reduces losses by approximately 15 % to 20 % compared with IE3. The construction with a 6-pole electric motor helps achieve a suitable compromise between torque, efficiency and low operating demands.

Operation in the range of 900-1000 rpm for stable process load

The nominal speed of 985 rpm falls into a segment that is practical for applications with a continuous medium flow, regulated throughput or higher system inertia. The motor has a nominal current of 41.8 A at △ 400 V connection and 24.23 A at Y 690 V connection, so it can be naturally integrated into low-voltage infrastructure with the option of suitable power supply settings. The power factor of 0.81 and efficiency of 93.7 % support economical operation in applications where the motor runs continuously.

Design parameters that support long service life and quieter operation

The IEC 200 mm frame provides a robust base for industrial deployment, and the packaging weight of 272 kg confirms a heavy-duty design suitable for more demanding operating conditions. Noise level of 74 dB(A) remains at a level that can be taken into account when installing the unit in technical areas. The rotor inertia of 0.4 kg*m² helps the system start more smoothly, and the 6312-C3 bearings on both the DE and NDE sides are selected for reliable standard industrial duty. The 2-M50X1.5 cable entries make connection easier in control panel and machine assemblies.

Starting and torque data for correct drive sizing

When designing a drive, the starting torque ratio Tst/Tn 2, the breakdown torque ratio Tmax/Tn 2.1 and the starting current ratio Ist/In 8.5 are important. These values help estimate the motor’s behaviour during start-up, short-term overload and cooperation with technology with higher starting resistance. The motor is therefore suitable for operations where repeated starting or smooth operation with power reserve is expected.

Use in production and process assemblies

The motor is used in pumps for water management and process circuits, in fans for air handling and cooling, in compressors with higher operating load, as well as in mixers, conveyors, grinders, granulation lines, presses, centrifuges and smaller production units. Its application is also supported by accessories with 3 PTC thermistors, which improve temperature monitoring of the windings under longer load. In environments where reliable start-up, precise technical coordination and long-term operating efficiency are required, this is a solution with a good reserve even for modernising older drives in production lines.

When designing for a specific application, also take into account the packaging dimensions of 862*492*656 mm and the handling method during installation. If you need to reduce energy costs, maintain compatibility with the power supply system and at the same time obtain a motor in stock, VYBO Electric will recommend a suitable connection and operating setting. Check whether the motor is suitable for your application.
