6-pole 11 kW electric motor for stable industrial operation
The 3LC-160L-6 electric motor with a power output of 11 kW and a rated speed of 980 rpm is intended for operations where drive technology must run smoothly, without unnecessary service intervention and while contributing savings and value to the complete solution. This 6-pole electric motor performs well in light and medium industry, OEM assemblies and smaller technological units that need reliable starting and consistent torque under load.
IE3 efficiency class reduces losses during normal operation and helps keep consumption under control even in applications with longer running hours. In practice, this means less pressure on energy costs and better use of available power, which is valuable to anyone designing or operating an asynchronous electric motor in repeated cycles.
IE3 efficiency class reduces costs in long-running operations
In many machine assemblies, an electric drive is assessed not only by rated power but primarily by how it behaves during daily operation. An IE3 electric motor is therefore a sensible choice wherever the motor runs regularly, handles fluctuating loads and must maintain long-term operating stability without disproportionate growth in consumption. In this type of use, efficient operation translates into running costs much faster than with designs offering less reserve.
For integrators and machine manufacturers, it is also important that the motor operates with a rated current of 22 A at △ 400 V and 12.75 A at Y 690 V, allowing sensible integration into standard industrial connections. This helps when designing switchgear, selecting protective devices and setting up the complete drive in line with the technological cycle.
Operation that keeps pace with the production line
In conveyor, pump and agitator drives, it is important that the motor does not fluctuate with changes in load and that its behaviour is predictable for both the designer and maintenance team. A rated speed of 980 rpm supports a stable operating regime in applications where smoothness, pulling force and adequate starting reserve matter. A starting torque ratio of 2 and breakdown torque ratio of 2.1 help when starting loaded mechanisms, while a starting current ratio of 7.2 simplifies power-supply sizing.
A noise level of 73 dB(A) contributes to a reasonable level of acoustic comfort in machine halls where technology is often located close to operators. For the user, this means a motor that can also be integrated into lines where not only performance but also the environment around the machine is considered.
Robust cast-iron frame increases assembly durability
A robust cast-iron frame is suitable wherever the motor operates under vibration, repeated switching or long-term operation on a rigid foundation. Reinforced cast-iron bearing shields and reinforced cast-iron feet help maintain mounting strength even under more demanding mechanical loads, which is particularly important for machines requiring precise alignment and assemblies sensitive to torsional stress.
This design is suitable for companies that do not view the motor merely as a separate component but as part of the complete machine. Practical servicing is also considered in the design, supported by cable glands 2-M40X1.5, DE bearing 6309-2RZC3 and NDE bearing 6309-2RZC3. Rotor inertia of 0.140 kg/m² supports predictable behaviour during starting and transitions between operating modes.
Dimensions and connection simplify integration into OEM machines
In OEM projects, installation discipline and use of space are also decisive. A frame size of 160 mm gives designers a clear basis for integration into the technology, while package dimensions of 822*407*566 mm and a packaged weight of 151 kg are useful for logistics, handling and shipping planning. The 3LC-160L-6 therefore performs well in assemblies where precise connection to existing mechanical components is important.
A 400/690 V supply is suitable for industrial assemblies with standard power systems and allows flexible integration into different types of applications. In practice, this is appreciated by both service and purchasing teams because it simplifies the selection of compatible components and reduces the risk of unnecessary modifications during installation.
Specific applications in everyday practice
This asynchronous electric motor is suitable for the following industrial applications:
- belt-conveyor drive in a packaging line
- screw-conveyor drive for bulk materials
- slat-conveyor drive in food processing
- centrifugal-pump drive in a water-treatment plant
- agitator drive in a chemical dosing tank
- fan drive in an air-handling unit
- compressor-unit drive in workshop technology
- granulation-machine drive in plastics production
- dry-mixture mixer drive in construction-material production
- roller-conveyor drive in wood-processing operations
- smaller-crusher drive in a recycling line
Proven basis for servicing and series production
When selecting a drive, the practical choice is often between an immediately available stock solution and long-term operational reliability. This model combines both because it is built for technologies that operate regularly, with an emphasis on savings, service life and simple integration into existing assemblies. This is also why the 3LC PRO series draws on more than 15 years of experience supplying industrial applications.
