A robust cast-iron frame gives the 3LC PRO 3LC-160M-4 motor the durability appreciated under everyday loads in light and medium industry. This 1500 rpm electric motor combines the efficiency and value of the 3LC-160M-4 model so that it performs well in machines where reliable starting, smooth running and long-term operational dependability are decisive.
A power output of 11 kW and rated speed of 1470 rpm provide a solid basis for conveyors, pumps, fans and mixing units. The 160 mm frame size makes integration into existing assemblies easier, and the 400/690 V supply allows the motor to be readily incorporated into common industrial power systems.
1500 rpm electric motor for smooth operation of production lines
In practice, this electric motor is suitable wherever stable performance without unnecessary fluctuations is expected. Three-phase electric motors with these characteristics are used in OEM machines as well as smaller technological units where every hour of operation counts.
The robust cast-iron frame improves the mechanical strength of the assembly and also helps withstand stress in demanding operation. Reinforced cast-iron bearing shields and reinforced cast-iron feet provide secure mounting in the machine, helping the motor cope better with vibration, frequent starts and longer duty cycles.

- Separator in food-processing technology.
Robust cast-iron frame for machines with higher mechanical stress
In environments where machines are started and stopped every day, a rigid construction is decisive for trouble-free operation. An asynchronous electric motor with this type of frame better withstands mechanical shocks and maintains stable mounting within the equipment over the long term.
This electric motor is designed for operation where consistent performance is expected even under increased load. The manufacturer’s years of experience are evident in the construction details that make deployment easier both in series production and replacement installations.
IE3 supports savings in everyday operation of a 1500 rpm electric motor
IE3 efficiency class shows its benefit particularly where the motor runs for a large part of the day. During long operating intervals, it helps keep consumption reasonably under control, which is important both for machine manufacturers and for operators evaluating drive payback over a broader time horizon.
Super high efficiency is particularly beneficial in applications with steady loads. Combined with a power factor of 0.85 and efficiency of 91.4%, it creates a drive suitable for technologies focused on economical operation.
Practical parameters for installation and long service life
A rated current of △ 400V 20.4 A and rated current of Y 690V 11.83 A simplify switchgear design and the selection of protective devices. A starting torque ratio of 2.2 and breakdown torque ratio of 2.3 assist with starting under load, while a starting current ratio of 7.7 supports correct sizing of the complete electrical system.
A noise level of 73 dB(A) remains reasonable for industrial premises, while rotor inertia of 0.085 kg/m² helps when assessing drive dynamics. Cable glands 2-M40X1.5 simplify connection in typical installations, and the DE bearing 6309-2RZC3 and NDE bearing 6309-2RZC3 support reliable operation over long periods.
Package dimensions of 752*407*566 mm and a packaged weight of 131 kg simplify logistics and installation planning in both workshops and assembly lines. If you need a 1500 rpm electric motor for a specific machine, order the 3LC-160M-4 model in good time to speed up commissioning of the technology.
