The 3000 rpm electric motor in the 3LC-160M1-2 version delivers efficiency and value that noticeably simplify drive design in light and medium industry and keep technology running at a stable pace. The 11 kW output and 2950 rpm speed are suitable for operations requiring a fast response to load, smooth starting and a sensible reserve for everyday production. In practice, this means fewer compromises when choosing between performance, space and operating costs.
3000 rpm electric motor for stable production-line operation
An asynchronous electric motor of this class fits machines that operate in repeated cycles and require reliable starting as well as dependable performance under prolonged load. The rated speed of 2950 rpm provides the dynamics needed where conveyors, mixers or pumps must accelerate quickly without unnecessary downtime. With a rated current of 19.6 A at △ 400V and 11.36 A at Y 690V, the drive integrates well into switchboard design and service-maintained production lines.
IE3 efficiency class – Super High Efficiency supports economical operation under normal load. An efficiency of 91.2% and a power factor of 0.89 help reduce energy losses and improve drive economy over longer production cycles. Whether used in single-shift, multi-shift or continuous operation, the electric motor therefore operates more efficiently and makes operating costs easier to plan.
Robust cast-iron frame for demanding industrial operation
The robust cast-iron frame increases resistance to vibration and helps maintain accurate alignment even where machines are started and stopped every day. Reinforced cast-iron bearing shields and reinforced cast-iron feet add structural rigidity that installers and maintenance teams appreciate when mounting the motor on a base frame. This design is practical in plants where long service intervals are expected and the operating environment does not tolerate weak points.
The manufacturer’s years of experience are evident in how the motor handles normal vibration, installation loads and repeated starts without unnecessary adjustments. A noise level of 81 dB(A) also allows sensible use in grouped assemblies where keeping acoustic conditions within reasonable limits matters. Rotor inertia of 0.054 kg/m² additionally supports predictable drive behaviour when calculating acceleration times.
3LC PRO for OEM machines and smaller technological units
In OEM applications, a key advantage is an electric motor that fits the machine concept without complicated modifications. The 3LC PRO model is suitable for smaller technological units where compact installation, stable performance and straightforward connection to existing production systems matter. Cable glands 2-M40X1.5 simplify power-cable routing and support a clean installation in both switchboard and machine assemblies.
DE bearing 6309-2RZC3 and NDE bearing 6309-2RZC3 provide a sound basis for long-term operation focused on reliability and service availability. This is important in applications where downtime costs more than the replacement part itself. The motor is therefore well suited to packaging lines, dosing systems, conveyor modules and process units that must operate to a precise rhythm.
Practical 400/690 V configuration for maintenance
The 400/690 V supply makes the motor easy to use in standard industrial networks as well as in assemblies that require switching between △ and Y connections. This flexibility helps when designing starts, sizing protective devices and carrying out service work. Maintenance teams also benefit from predictable motor behaviour in operations where loads vary according to production orders.
Typical applications for this three-phase electric motor include centrifugal chemical pumps, conveyor belts for granulate, screw conveyors for bulk materials, paint mixers, drying-system ventilation units, compressor units, packaging machines, beverage filling lines, briquetting presses, film cutters, plastic regranulate mills, aggregate sorters, roller feeders, cooling-circuit pumps and smaller extrusion lines.
Order a motor for production without unnecessary downtime
The 3LC PRO 3LC-160M1-2 model is ready for operations that need a balance of performance, efficiency and mechanical durability in one solution. If your workshop or production line needs to operate reliably under regular load, order this motor in good time and reduce the risk of downtime during the next planned expansion of your technology.
This 3000 rpm electric motor is a sensible basis for both drive modernisation and new machines where rapid commissioning is important. When available from stock, the decision becomes a practical step that saves both time and service capacity.
