Electric motor 15 kW, 2960 rpm, 400 V / 690 V, 4LC-160M2-2 LV

When selecting a drive for pumps, fans, compressors and heavier industrial units, it is worth focusing on operating reserve, efficiency and service availability. The 4LC-160M2-2 400/690 V model with an output of 15 kW operates in the speed class of 2900-3000 rpm and, thanks to its IE4 design, can reduce energy losses by approximately 15 % to 20 % compared with IE3 class solutions. In practice, this means lower thermal loading, more stable operation and better operating economy during long daily cycles. This three-phase motor 400/690 V is suitable wherever reliable starting and smooth power transfer are required without unnecessary compromises.

The 160 mm frame size design uses an all-cast-iron construction designed to absorb vibrations and increase durability in environments with increased dust, humidity or aggressive fumes. For the operator, this brings less transmitted shock to the bearings, lower mechanical stress on the mounting and longer-term stability when mounted on a solid base as well as on a machine frame. With regard to high-power drives, this is a low-voltage asynchronous electric motor designed for continuous operation in industrial applications where durability and easy integration into existing infrastructure are important.

Operation in the 2900-3000 rpm range for stable performance in technology

The rated speed of 2960 rpm places the motor precisely in a segment where high circumferential speed and stable behaviour under changing load are important. The starting ratio Tst/Tn 2, breakdown ratio Tmax/Tn 2.3 and starting current Ist/In 9.5 provide sufficient reserve when starting pumps, fans and compressor units. The power factor of 0.89 and efficiency of 93.3 % support economical operation, which is crucial for controlling energy consumption in multi-shift lines.

In terms of noise, the motor reaches 81 dB(A), so with correct installation it is possible to maintain acceptable operating conditions even in halls with a higher density of technology. The rotor inertia of 0.1 kg*m² helps with the dynamic response of the drive and simplifies the design of starting modes in applications where rapid attainment of operating speed is required. Combined with precise bearing and winding design, this creates a drive that fits well into a production environment with an emphasis on long-term stability and service predictability.

Connection and mounting elements for easier integration into machines

For integration into switchboards and cable routes, 2-M40X1.5 cable glands are available, allowing clear routing of the power supply and related signals. The DE 6309-2RZC3 bearing and the NDE 6309-2RZC3 bearing are selected to support reliable operation under standard industrial load while also simplifying service intervention during planned maintenance. The 3 PTC thermistors help with thermal protection of the winding and increases safety in operations where emphasis is placed on monitoring thermal stress.

Thanks to these elements, the motor is suitable for both new installations and modernisation of existing drives, while VYBO Electric technical advice can help with selecting the appropriate connection method, mounting and operating mode. As a brand with its own research and development and a strong position in the market in Central Europe, it offers solutions that combine performance, service support and long-term operating certainty. If you need a motor for demanding duty cycles, check whether the motor is suitable for your application.

Industrial use for drives with increased demands on efficiency

The motor is suitable for systems where super premium efficiency is decisive and where every improvement in efficiency is reflected in operating costs. For pump stations, extraction fans, compressors and process transmissions, it provides stable 15 kW output with 400 V / 690 V supply and helps maintain efficient operation even with a higher number of starts. In such conditions, precise matching between the electric motor and the machine duty point is important so that neither energy nor mechanical reserve is wasted.

For businesses with low-voltage infrastructure, compatibility with common industrial protection, control and monitoring elements is also essential. The combination of robust construction, suitable bearings and thermal protection creates the conditions for long service life in continuous operation. When designing the system, we therefore recommend verifying the load, starting conditions and cooling method so that the drive uses its potential as efficiently as possible.
