4-pole 15 kW electric motor for economical operation
The 4-pole electric motor designated 3LC-160L-4 operates with a power output of 15 kW and a rated speed of 1470 rpm, enabling it to reliably drive pumps, conveyors and mixers in light and medium industry. In practice, it provides savings wherever stable operation, a sensible performance reserve and return on investment in drive technology are decisive. The 3LC-160L-4 is therefore also suitable for OEM machines and smaller technological units that need a motor without unnecessary compromises in operation.
IE3 efficiency class helps reduce energy consumption under normal load and keeps operation economical even during longer duty cycles. This makes the asynchronous electric motor attractive for applications where not only purchase costs but also costs over the entire equipment life cycle are monitored.
IE3 efficiency class for lower operating costs
The robust cast-iron frame provides secure mounting within the assembly and improved resistance to vibration generated by everyday starting and loading. Reinforced cast-iron bearing shields and reinforced cast-iron feet are a solution for environments where long-term stability and a rigid connection to the machine frame are expected from the motor.
Starting characteristics are also important when integrating the motor into machinery. A starting torque ratio of 2.2 and starting current ratio of 7.8 give the designer confidence when designing a load that starts against resistance. A breakdown torque ratio of 2.3 also supports a smooth transition into operating mode without unnecessary performance fluctuations.

Dimensions, bearings and connection to the technology
The 160 mm frame size facilitates installation in standardised assemblies and simplifies replacement in existing drives. Cable glands 2-M40X1.5 enable practical connection in switchgear and machine installations, while the DE bearing 6309-2RZC3 and NDE bearing 6309-2RZC3 support precise rotor operation and long-term reliability.
An asynchronous electric motor in this class also performs well where the machine has limited installation space. Package dimensions of 822*407*566 mm and a packaged weight of 162 kg assist with planning logistics, installation and handling both in production and service warehouses.
Operating characteristics that support long shifts
A power factor of 0.86 and efficiency of 92.1% support balanced operation over extended periods, which is particularly important in pumping stations, compressor assemblies and conveyor systems. A noise level of 73 dB(A) helps maintain acceptable working conditions in operations where the motor forms part of a continuous technological process.
Rotor inertia of 0.112 kg/m² is important when designing acceleration and deceleration of the system, especially if the motor works with a gearbox, coupling or belt drive. Combined with a rated current of △ 400V 27.3 A and a rated current of Y 690V 15.83 A, this makes it easier to select the connection according to the specific power-distribution system.
Applications in light and medium industry
The motor is used in clearly defined applications where reliable operation and easy integration into the line are decisive.
- Bulk-material conveyor in a packaging line.
- Belt-conveyor drive in an aggregate sorting plant.
- Mixer in food pre-processing.
- Process-water pump in a utilities treatment plant.
- Extraction fan in a paint shop.
- Screw feeder in a dosing system.
- Drive unit for a smaller briquetting line.
- Drum-screen drive in a recycling facility.
- Compressor unit in a workshop compressed-air network.
- Roller transport system in an assembly hall.
Practical experience that speeds up selection
When designing a drive, it is worthwhile to draw on real experience of what works in operation. More than 15 years of experience with motors and drives helps determine whether starting reserve, frame strength or easy replacement in an existing machine is most important for a given application. In this category, the IE3 electric motor performs well wherever consumption, stability and service practice are considered together.
