Economical operation for production lines that run every day
The 6-pole electric motor 3LC-225M-6 delivers 30 kW of power and an ideal balance between purchase price and energy savings. In practice, this means a sensible choice for drives that must operate reliably, without unnecessary downtime and without pressure from excessive operating costs. For light and medium industry, an electric motor of this type is often exactly the component that balances the requirements for power, starting and long-term operating economy.
The 3LC-225M-6 operates at 985 rpm, which supports stable drive performance in technologies where smooth torque transmission and predictable machine behaviour are important. IE3 efficiency class supports lower consumption under normal load and, combined with disciplined operation, can noticeably reduce pressure on the energy budget. For machine manufacturers and integrators, it is a practical foundation for designing a modern drive that is also easier to justify during internal investment approval.
IE3 efficiency class means lower losses in normal operation
IE3 efficiency class is suitable wherever the motor is not used only occasionally but forms part of the regular production cycle. Super high efficiency is particularly noticeable when the equipment runs for long hours and differences in consumption translate into real costs. This asynchronous electric motor therefore fits drives where not only performance but also long-term return is monitored.
In drive technology for conveyors, pumps or fans, efficiency is one of the main reasons this model appears in OEM manufacturers’ specifications. Rated current at △ 400V is 56.2 A and at Y 690V is 32.58 A, simplifying both switchgear design and protection settings for the specific network. The manufacturer also draws on the manufacturer’s years of experience, reflected in a design intended for repeated industrial loading.
Robust cast-iron frame keeps the motor in a stable position
A robust cast-iron frame gives the construction reserve capacity appreciated in machines exposed to vibration, frequent starting or precise motor-position requirements. Reinforced cast-iron bearing shields and reinforced cast-iron feet increase assembly rigidity and help maintain mounting precision even in long-term operation. For smaller technological units, this is an advantage that reduces the risk of unwanted installation deformation and makes servicing easier.
A noise level of 74 dB(A) is acceptable for many industrial installations where both performance and the working environment are considered. Rotor inertia of 0.624 kg/m² supports consistent starting and assists in designing a drive with the correct acceleration profile. Combined with 6313-C3 bearings on both the DE and NDE sides, it is a solution prepared for operation in typical industrial cycles.
For OEM machines and compact technological units without unnecessary compromises
A 225 mm frame and package dimensions of 1012*652*846 mm simplify planning installation in machine bases and custom OEM assemblies. Cable glands 2-M50X1.5 provide practical routing of the incoming supply and a clean connection to industrial switchgear. Integrators also benefit from an electric motor that can be incorporated into assemblies designed for precise service access and straightforward replacement during planned maintenance.

Starting behaviour that helps with drive design
Designers also need to know how the motor behaves during starting and overload peaks. A starting torque ratio of 2, breakdown torque ratio of 2.1 and starting current ratio of 6.9 provide a good basis for designing a drive with standard industrial requirements. In practice, this helps when selecting the coupling and gearbox and when sizing protective and switching devices.
Data that simplify installation and servicing
With a packaged weight of 378 kg, handling suitable for standard workshop logistics should be planned. When designing the assembly, it is also useful that the 3LC PRO series is based on practical details that simplify repeatable installation in serial machines. This approach is suitable wherever not only immediate performance but also spare-part supply stability and service predictability are important.
If you need a drive that should operate economically while handling typical industrial loads, 3LC-225M-6 is ready to perform this task without unnecessary compromises. Take advantage of the offer and choose a motor that supports both energy savings and reliable operation of your technology.
