In conveyors, pumps, mixers and production lines, a 3000 rpm electric motor can determine whether the technology keeps pace with production without unnecessary downtime. The 3LC-200L1-2 model delivers 30 kW of power to help maintain stable operation while also providing scope for savings in applications where both energy costs and reliability during long shifts are monitored.
In practice, it is particularly useful as a solution for light and medium industry, OEM machines and smaller technological units. Three-phase electric motors in this class are used where straightforward integration into an existing assembly, a sensible starting reserve and reliability during repeated starts are required. An electric motor with a shaft height of 200 mm also works well in compact machines where space for servicing and installation is important.
3000 rpm electric motor for stable operation of production technology
The rated speed of 2970 rpm supports smooth power transmission in applications requiring a fast working pace and precise response. As a 400 V electric motor in a △ 400V connection with a rated current of 52.1 A, it fits standard industrial power systems, while the Y 690V connection with a current of 30.2 A enables flexible use in equipment with a higher voltage level.
Robust cast-iron frame provides firm support under long-term load and reduces sensitivity to vibration in more demanding operation. Reinforced cast-iron bearing shields and reinforced cast-iron feet help maintain accurate alignment, which is important during frequent starts, fluctuating loads and mounting on the machine frame.
- 30 kW output covers drives for conveyors, pumps and process mixers.
- Rated current of 52.1 A at △ 400V simplifies switchboard and protection design.
- Rated current of 30.2 A at Y 690V expands application options in industrial units.
- Starting torque ratio 2 helps manage starting without unnecessary mechanical stress.
- A noise level of 84 dB(A) is suitable for areas where workplace acoustic load is monitored.
IE3 efficiency for lower consumption during long shifts
IE3 efficiency class – Super High Efficiency supports more economical operation, particularly where the motor runs for many hours each day. In smaller technological units and OEM assemblies, the difference is reflected in better energy utilisation and consistently balanced operation without having to change the drive concept.
An efficiency of 93.3% and a power factor of 0.89 help when designing drives in plants where not only consumption but also the quality of operating conditions is monitored. Combined with a starting current ratio of 7.6 and rotor inertia of 0.180 kg/m², the result is a motor with predictable behaviour during starting and repeated cycles.
Installation, bearings and cable connection in practice
DE bearing 6312-C3 and NDE bearing 6312-C3 support long bearing life under typical industrial loads. Cable glands 2-M50X1.5 simplify wiring in switchboards and confined technological spaces where fast installation without improvisation is important.
Packaging dimensions of 862*492*656 mm and a packaging weight of 249 kg simplify logistics during goods receipt and installation planning. With supply from the proven manufacturer and distributor VYBO Electric, the technician can be confident of working with a solution that fits standard industrial procedures and service practices.
Applications in light and medium industry
The 3LC-200L1-2 model is suitable for belt conveyors used in material sorting, centrifugal pumps for process water, extraction fans, screw compressors, dry-mix mixers, rotary spreaders, roller conveyors, cutting lines and smaller pressing units. In each of these machines, it is important that the 3000 rpm electric motor maintains a stable rhythm and does not limit the performance of the complete assembly.
When selecting a motor for OEM machines, compatibility with standard mounting dimensions and easy integration into serial production are also important. A 400 V electric motor is therefore suitable for projects where the manufacturer needs a repeatable assembly, predictable operating behaviour and servicing that does not prolong downtime.
Why 3LC PRO is suitable for serial machines
3LC PRO in this configuration appeals to designers, maintenance teams and purchasing departments because it combines performance, efficiency and robust mechanical construction in a single solution. In practice, this means less time spent tuning the drive and more time with the technology working for production.
For projects where service life, installation readiness and energy balance are important, this is a motor that fits everyday industrial practice without unnecessary modifications. Contact us.
