1500 rpm electric motor for drives that must keep production running at a stable pace
A rated power output of 132 kW and speed of 1485 rpm give the 3LC PRO 3LC-315M-4 model an ideal balance between purchase price and energy savings. This 1500 rpm electric motor is designed for applications where long-term operation, repeated starts and careful evaluation of total drive costs are expected.
In practice, it is a solution for medium-sized businesses and large factories that need reserve capacity for technological lines, conveyors and units operating within industrial automation systems. As an asynchronous electric motor with a 400/690 V supply, it performs well wherever reliable operation without unnecessary maintenance intervention is required. IE3 efficiency class supports lower consumption under normal load and improves operating economics over time.
IE3 efficiency class reduces losses during long shifts
An IE3 electric motor is suitable for operations where every kilowatt-hour matters. Super high efficiency is most noticeable in machines with long production cycles, where the motor runs under stable load and reduces pressure on the energy budget. Combined with a power factor of 0.89, it provides a suitable basis for designing a drive intended to keep operation predictable even at higher utilisation.
A starting torque ratio LRT/RLT of 2 and starting current ratio LRA/RLA of 7 are parameters designers consider when sizing protective devices, frequency converters and starting circuits. A breakdown torque ratio BDT/RLT of 2.2 helps under loads where short-term resistance peaks occur. Rated current of △ 400V 224 A and rated current of Y 690V 129.86 A are also important for design, enabling precise integration into power-distribution and starting schemes.
Robust cast-iron frame for demanding installation and operating conditions
The construction with reinforced cast-iron bearing shields and reinforced cast-iron feet provides rigid mounting in machine assemblies where frame stability and resistance to vibration are decisive. This robust cast-iron frame is suitable for installation in space-intensive technology where precise alignment and reliable torque transmission are required.
DE bearing 6319-C3 and NDE bearing 6319-C3 support smooth operation under loads typical of industrial drives. Rotor inertia of 4.210 kg/m² assists with designing acceleration and coast-down, which engineers appreciate in applications with greater mechanical coupling. A noise level of 88 dB(A) is important when planning the workplace, enclosures and operator-protection measures.
Connection and handling prepared for industrial installation
Cable glands 2-M63X1.5 assist with switchgear and cable-route design, simplifying secure installation of the power supply into the motor terminal area. Package dimensions of 1412*727*1026 mm and a packaged weight of 989 kg should be considered when receiving, storing and planning installation on the line. In environments where production continuity is critical, these details shorten preparation time and reduce the risk of unplanned downtime.
Specific use in machines and technological units
The 3LC-315M-4 model is suitable for the following applications:
- Main drive of a belt conveyor in a bulk-material packaging line.
- Agitator drive in a chemical reactor with continuous operation.
- Drive motor for a screw compressor in a technological station.
- Motor for an aggregate crusher in construction and quarry processing.
- Pumping-unit drive for a cooling-water circulation circuit.
- Main fan motor for dust extraction in wood-processing production.
- Extrusion-line drive in plastic-profile production.
- Motor for a rolling station in metal-processing operations.
- Drum-mixer drive in food-processing technology.
- Main drive of a sorting conveyor in a material-logistics hub.
