A robust cast-iron frame helps maintain drive stability during demanding shifts where durability, service reliability and the long-term efficiency of the 3LC-160M-6 are decisive. This 1000 rpm electric motor is suitable wherever smooth starting, consistent performance and reasonable operating costs in everyday production are expected from a three-phase drive.
In light and medium industry, OEM assemblies and smaller technological units, this electric motor helps keep the process running without unnecessary downtime. When designing the drive, a power output of 7.5 kW, frame size 160 mm, 400/690 V supply and rated current of 15.4 A at △ 400V simplify integration into standard power systems and machine assemblies.
1000 rpm electric motor for production lines with smooth operation
A rated speed of 980 rpm gives the machine a practical operating rhythm for conveyors, mixing units and process equipment in continuous operation. In practice, this means less abrupt acceleration, better control of transmitted torque and smoother interaction with the other parts of the technology. With a rated current of 8.93 A at Y 690V, the connection remains flexible even in solutions using a dual-voltage configuration.
Robust cast-iron frame for everyday industrial loads
The cast-iron construction is advantageous in machines operating under vibration, in dusty environments or during longer duty cycles. Reinforced bearing shields and rigid cast-iron feet support more precise mounting, resulting in smoother operation and improved resistance to repeated loading. A packaged weight of 116 kg is also important, indicating a robust construction suitable for rigid installations.
- Suitable for conveyor modules in packaging lines.
- Suitable for pumping units in water-treatment technology.
- Suitable for fans in extraction systems.
- Suitable for agitators in chemical media preparation.
- Suitable for roller conveyors in internal transport.
IE3 efficiency class for lower losses under normal load
IE3 efficiency class helps reduce unnecessary losses during operation, which is particularly important wherever the motor runs for long hours in a steady state. Super high efficiency is most noticeable in equipment that remains running throughout the shift and where even small differences in consumption affect the monthly result. A power factor of 0.79 and efficiency of 89.1% complete the profile of a motor intended for long-term use.
Machine manufacturers also value predictable starting behaviour. A starting torque ratio of 2, breakdown torque ratio of 2.1 and starting current ratio of 7 support sensible behaviour during start-up and short-term load fluctuations. An asynchronous electric motor of this type therefore fits well into assemblies requiring reliable drive performance without complicated adjustment.
9 applications for OEM machines and smaller technological units
In practice, this electric motor is used in briquetting lines, belt conveyors, feed mixers, containerised pumping stations, extraction fans, horizontal agitators, granulators, packaging machines and compact pressing equipment. The manufacturer’s years of experience are also evident in details that simplify installation and long-term operation in serial assemblies.
Cable glands and bearings for easier integration
Two cable glands 2-M40X1.5 are practical for machine installation, simplifying power-cable routing and cable organisation in the switchgear or on the equipment frame. DE bearing 6309-2RZC3 and NDE bearing 6309-2RZC3 support stable operation and predictable servicing during repeated use.
Rotor inertia of 0.106 kg/m² and a noise level of 73 dB(A) complete the profile of a motor prepared for real workshop and production conditions. Package dimensions of 752*407*566 mm simplify storage, handling and shipping planning. If you need a motor for a reliable production drive, order the 3LC-160M-6 today while it is available for deployment in your technology.
