Electric motor 11 kW, 2960 rpm, 400 V / 690 V, 4LC-160M1-2 LV

Flow fluctuations, pressure spikes and frequent starting can quickly reveal a weak point in a high-performance drive assembly. The 4LC-160M1-2 model with an output of 11 kW is therefore designed for operation in the speed range of 2900-3000 rpm, where it helps maintain stable performance, precise response and a sensible reserve for long-term load. Its construction uses premium materials and windings optimised for efficient operation, which is especially important where reliable starting, low losses and consistent operation are expected.

Efficiency and serviceability at 2900-3000 rpm

In this speed class it is particularly suitable for pumps, fans and compressors, where the balance of efficiency and available torque is decisive. As a IE4 electric motor it delivers high efficiency of 92.6 % and a power factor of 0.89, helping to make better use of electrical energy even during long operating periods. The noise level of 81 dB(A) remains within a reasonable range for industrial use, and the shaft height of 160 mm makes replacement in existing machine assemblies easier.

Operating reserve for industrial drives

This three-phase motor 400/690 V operates with a rated current of 19.3 A at delta 400 V and 11.19 A at star 690 V, which simplifies its integration into low-voltage infrastructure. The starting torque ratio Tst/Tn is 2, the breakdown torque ratio Tmax/Tn reaches 2.3 and the starting current ratio Ist/In is 9.5, so the motor provides sufficient starting performance even in loaded applications. The rotor inertia of 0.1 kg*m² supports smooth acceleration and stable running during repeated starting.

Construction ready for pumps, fans and large machines

DE and NDE bearings of type 6309-2RZC3 increase operating reliability and reduce the need for frequent maintenance, which is appreciated by drives for light and heavy industry. The 2-M40X1.5 cable entries provide practical connection, while the equipment also includes 3 PTC thermistors for winding thermal protection. The package weight of 116 kg and package dimensions of 752*407*566 mm make logistics easier when delivering to the installation site.

Typical use in stable and demanding operation

The motor is suitable for central pumping stations, air handling units, screw compressors, conveyors, mixers, chippers, process fans, industrial power units, pumping systems, cooling circuits, pressing lines, granulation equipment, compressor rooms, machining centres and other machines requiring long-term performance. Thanks to the in-house development of the VYBO Electric brand and the experience gained over many years of production, the customer receives a solution ready for repeated starts and stable load in real operating conditions.

Integration into existing drives without unnecessary compromises

In practice, it proves itself where efficiency, durability and safe starting need to be combined into one unit. The rated speed of 2960 rpm, efficiency of 92.6 % and power factor of 0.89 create a solid basis for long-term use in technologies requiring stable performance. If you are looking for a motor for a new assembly or a replacement for an existing operation, this model is a sensible choice for designers and buyers alike; request a quotation and choose a solution with an emphasis on reliable operation and premium workmanship.
