Electric motor 7,5 kW, 980 rpm, 400 V / 690 V, 4LC-160M-6 LV

Unwanted outages, load fluctuations and unnecessarily high consumption can slow down the entire operation, so when choosing a motor it is worth opting for a solution that can handle stable output and long-term load. The 4LC-160M-6 model with an output of 7.5 kW belongs to the speed segment of 900-1000 rpm and is designed to deliver reliable operation in low-voltage infrastructure, with an emphasis on efficiency. Its basis is a design with advanced materials and well-considered windings that help maintain high operational reliability even in conditions where long service life and minimal downtime are expected.

Efficient performance for operation at rated speed 900-1000 rpm

For pumps, fans and compressors, it is crucial that the motor maintains stable speed without unnecessary losses. This IE4 electric motor achieves an efficiency of 91.3% and a power factor of 0.76, which helps reduce energy costs in everyday operation. At a supply voltage of 400 V it draws 15 A, and when connected in Y at 690 V it draws 9 A, so it can be suitably integrated into standard industrial systems.

Rated current, speed of 980 rpm and 6-pole arrangement create a suitable combination for applications where smooth starting and an even torque curve are important. The starting torque ratio Tst/Tn of 2 and the breakdown torque ratio Tmax/Tn of 2.1 provide a reserve at start-up and during transient states, while the starting current ratio Ist/In of 8 corresponds to industrial use with a clearly defined load.

Construction that helps with long operating life

For a motor with a centre height of 160 mm, not only output but also mechanical durability and sensible thermal behaviour play an important role. The DE 6309-2RZC3 and NDE 6309-2RZC3 bearings support balanced rotor operation, whose inertia is 0.1 kg*m². Noise at 73 dB(A) remains at a level that operations can accommodate without excessive acoustic load.

In practice, the accessories in the form of 3 PTC thermistors also help, extending monitoring of the winding temperature condition. The 2-M40X1.5 cable glands make wiring easier in switchboards and when installing into machine assemblies. This approach will be appreciated especially by operations that need a solution with an emphasis on reliable protection and consistent output.

Use in industrial drives with high demands

• Pumps benefit from stable operation during continuous fluid conveying in process and water management applications.
• Fans benefit from steady speed in ventilation and industrial extraction.
• Compressors gain a motor suitable for long-term operation with regular load.
• Conveyor systems use a drive with reliable starting and smooth torque transmission.
• Mixers in the chemical industry appreciate consistent output with varying medium resistance.
• Pumping stations benefit from a robust design for repeated starts and long runs.
• Cooling circuits benefit from precise control with low-voltage power supply.
• Machine lines in the processing industry require a motor with a reserve for transient states.
• Production units operating at 400 V use the motor as a reliable main drive.
• Process units use IE4 efficiency to reduce energy demand.
• Pressing equipment needs stable torque under cyclical load.
• Crushers and mulching units benefit from the durable design of the rotor and bearings.
• Drying lines appreciate quieter operation during long-term use.
• Filtration units need a motor with long service life and reliable temperature monitoring.
• Large machines in industrial halls gain a drive ready for demanding operation.

Installation and mechanical design for easier mounting

The packed weight of 116 kg and packed dimensions of 752*407*566 mm provide a clear idea of logistics and handling when receiving the goods. The motor can therefore be planned into installation even before it is mounted into the machine itself, which makes preparation for servicing and warehouse management easier. Thanks to this, it is suitable for integrators as well as maintenance teams that need to have a spare part ready without delay.

VYBO Electric is based on its own development and many years of experience in the manufacture of electric motors, which is reflected in the emphasis on material quality and reliable operation. If you are looking for a drive for pumps, fans, compressors or other machines with continuous load, this model is a sensible choice for modern industrial use.
