Electric motor 11 kW, 1475 rpm, 400 V / 690 V, 4LC-160M-4 LV

In production lines, pumps and fans, it often comes down to whether the drive can handle stable operation without unnecessary losses and overheating. The 4LC-160M-4 model with an output of 11 kW belongs to the speed class in the range of 1400-1500 rpm, so it is suitable where a low-voltage motor needs to maintain constant output while remaining economical. As an IE4 electric motor, it uses a solution designed for higher efficiency, while its design is based on advanced materials and sophisticated windings that reduce losses in normal and demanding operation.

Economical operation under long-term load

This design is suitable for operations where the motor runs for much of the day and every percentage point of efficiency affects energy consumption. An efficiency of 93.3 % and a power factor of 0.83 support balanced electrical input, while the rated speed of 1475 rpm helps maintain stable output in applications with steady operation. For operators, this type of motor means lower heat losses, better use of input energy and more reliable operation in environments where a long duty cycle with few shutdowns is expected.

Use in demanding industrial operations

This 4-pole electric motor is suitable for drives in light and heavy industry, especially for pumps, fans, compressors, conveyors, mixers, machine tools and other equipment requiring reliable operation on a 400 V or 690 V mains supply. The shaft height of 160 mm supports secure mounting in machines with higher mechanical load, and the 6309-2RZC3 bearings on both the DE and NDE sides contribute to stability and greater operational reliability. Thanks to the 2-M40X1.5 cable glands, practical connection in control cabinet and machine assemblies is made easier.

Operational safety and integration readiness

The equipment includes 3 PTC thermistors, which help monitor winding temperature and protect the motor in more demanding operation. When selecting for systems with frequent starts, fluctuating load or higher demands on operational discipline, it is also important that the starting torque ratio of 2 and the breakdown torque ratio of 2.3 provide scope for technically balanced deployment. The VYBO Electric brand draws on long-term development and experience in the field of industrial electric motors, which is reflected in its well-considered design and the use of premium materials.
