The robust cast-iron frame gives this solution a solid foundation in applications where continuous load, vibration and long production shifts are expected. The 3LC-315L2-6 1000 rpm electric motor delivers efficiency and value for medium-sized companies and large factories that need to maintain production flow without unnecessary downtime.
When designing the drive, you will appreciate stable operation at 990 rpm, which is suitable for applications with higher torque and sensitive starting conditions. The three-phase electric motor is easier to integrate into existing lines where reliable power, a sensible operating reserve and predictable servicing characteristics are required.
1000 rpm electric motor for smooth operation of production systems
This IE3 electric motor is designed for applications that need to combine long-term loading with reasonable operating costs. The IE3 efficiency class supports lower energy consumption under normal load and, in practice, helps during continuous operation of technology where every saving contributes to annual results.
In technical practice, it performs well in media pumping, conveyor systems and machines with higher starting resistance. Thanks to the rated speed of 990 rpm, the drive remains easy to specify for designers who need to balance torque requirements, thermal load and the stability of the complete assembly.
Robust cast-iron frame for engineers dealing with real operating conditions
The cast-iron frame helps absorb mechanical stress and maintain motor geometry even under prolonged loading. Reinforced cast-iron bearing shields and reinforced cast-iron feet increase durability on base frames, in pumping stations and in drives exposed to higher vibration.
This solution is beneficial where the motor is installed in robust units and a long service interval is expected. Industrial practice confirms that three-phase electric motors of this class are used in thousands of industrial installations, from simple machine assemblies to larger technological systems.
IE3 efficiency and performance that fit production discipline
For operators of halls and production lines, it is important that the motor can handle repeated starts and steady load without unnecessary fluctuations. The starting and breakdown torque ratios help when designing a drive in situations where reliable acceleration of the system and a secure transition to operating speed are essential.
The rated current of 232 A at △ 400V and 134.49 A at Y 690V simplifies sizing of switchboards, protective devices and cable routes. Installation and service teams will also value the 2-M63X1.5 cable glands, DE bearing 6319-C3 and NDE bearing 6319-C3, which support disciplined long-term operation.
Real applications in lines, pumps and conveyors
The 3LC PRO model is suitable for conveyor systems, mixing units, fan assemblies, compressor assemblies, briquetting presses, material crushers, process agitators, centrifugal pumps, drainage stations, belt conveyors, granulators, fibre winders and operating drives in raw-material processing.
Operating data such as a noise level of 83 dB(A), rotor inertia of 6.824 kg/m², package weight of 1069 kg and package dimensions of 1412*727*1026 mm are also useful when planning installation. These values simplify logistics, handling and installation in the structure without unnecessary surprises at the installation site.
If you need a 1000 rpm electric motor for production technology that must not slow down your daily output, order the 3LC-315L2-6 model today. It is ready immediately for 400/690 V projects, and for enquiries we recommend acting quickly to maintain continuity of supply.
