Rated power of 15 kW and a speed of 2950 rpm make the 3LC-160M2-2 a practical basis for operations where a 2-pole electric motor must provide fast acceleration, stable running and reasonable operating costs. In light and medium industry, this combination of power and speed is well suited to drives that operate every day without long interruptions.
This IE3 electric motor provides benefits that are immediately noticeable in drive technology, both in energy consumption and service planning. Customers in OEM manufacturing and smaller technological units value a motor that integrates well into an existing assembly without requiring complicated compromises in switchboard design or mechanical coupling.
IE3 efficiency class – Super High Efficiency supports the long-term economy of normal-load operation. In serial production, pumps, fans or conveyors, the savings are most apparent where the motor runs for long hours and differences in losses accumulate with every shift.
Experience with these types of assemblies is built over many years and makes a difference when selecting a drive. More than 15 years of supplying industrial applications helps in choosing a solution that matches not only rated power but also the starting method, load characteristics and required service availability.
2-pole electric motor for fast production-line acceleration
The 2-pole motor design with a rated speed of 2950 rpm is suitable where the drive needs to respond quickly and reach operating speed without unnecessary delay. For a production line, this means smoother starting, a shorter time to operating mode and better utilisation of the production cycle.
- Rated current △ 400V: 26.5 A supports power-supply design in standard industrial networks.
- Rated current Y 690V: 15.36 A is suitable for connection according to project documentation at higher voltage levels.
- Starting torque ratio 2 helps when starting loads that require reliable breakaway torque.
- Breakdown torque ratio 2.3 improves reserve during transient drive conditions.
- Starting current ratio 8.1 must be considered when designing protection and control.
Cast-iron frame for long service life in demanding operation
The robust cast-iron frame, reinforced cast-iron bearing shields and reinforced cast-iron feet provide mechanical stability in applications where vibration, frequent starting and rigid machine mounting are expected. This construction is practical for installation in technological units where the drive must maintain accurate geometry even under prolonged load.
In an asynchronous electric motor, this means a lower risk of inconvenient downtime caused by mechanical stress. For maintenance, the DE 6309-2RZC3 and NDE 6309-2RZC3 bearing arrangement is also important, supporting stable operation in real industrial conditions.
Dimensions and weight for easier integration
Packaging dimensions of 752*407*566 mm and a packaging weight of 129 kg are important for goods receipt, storage and installation into a production line. Rotor inertia of 0.062 kg/m² helps when designing starting conditions and selecting a suitable switching method according to the type of load.
IE3 energy efficiency in everyday operation
An efficiency of 91.9% and a power factor of 0.89 provide a good basis for economical operation in applications where the motor runs during most shifts. In practice, this is particularly valuable to operations that monitor energy costs while still requiring full drive performance.
A noise level of 81 dB(A) should be considered when locating the machine in a production hall or close to operators. With suitable machine enclosure and correct mounting, the motor can be integrated into existing drive technology without unnecessary structural modifications.
Six specific applications for OEM and industrial assemblies
The 3LC PRO model is suitable for smaller technological units as well as machines requiring a reliable 2-pole electric motor with fast acceleration and rigid mounting.
- Centrifugal pump for cooling-water circulation in a processing line.
- Industrial radial fan for extracting air from a paint booth.
- Chain conveyor in packaging technology with stable traction.
- Lower-power extruder for plastics production.
- Compressor assembly in a service station with repeated starts.
- Mixer in a food-processing technological unit with continuous operation.
Operating details that simplify installation and servicing
Cable glands 2-M40X1.5 simplify routing the supply cable when connecting the motor to a switchboard and help keep cabling neatly arranged. For maintenance, it is also important that the motor can be incorporated into standard service plans without unusual interventions in the mechanical part of the machine.
