1000 rpm electric motor for stable operation of production technologies
The 3LC PRO 3LC-315L1-6 electric motor with a power output of 110 kW is designed for operations where an ideal balance between purchase price and energy savings is decisive. This 1000 rpm electric motor runs at a rated speed of 990 rpm, making it well suited to continuous-load applications where smooth power delivery and drive stability are important.
In practice, technicians particularly value how an IE3 electric motor helps reduce losses during long-term use. IE3 efficiency class is reflected in operating costs on energy-intensive lines and creates room for more rational energy management when modernising drives. This approach is important for medium-sized businesses and large factories seeking to optimise consumption without disrupting the production rhythm.
Robust cast-iron frame for demanding industrial applications
A robust cast-iron frame helps maintain mechanical rigidity under vibration, continuous load changes and installation in technological units with higher dynamic demands. Reinforced cast-iron bearing shields and reinforced cast-iron feet increase structural durability in long-term operation, which is particularly beneficial in engineering production and industrial automation.
An asynchronous electric motor in this class integrates well into drives where reliable starting, stable torque and minimal service intervention are expected. Designers also value rotor inertia of 6.077 kg/m², which helps when designing acceleration and sizing downstream transmissions.
Starting, current and torque values for drive design
Starting is characterised by a starting torque ratio of 2 and starting current ratio of 6.7, which are important when selecting the starting method and assessing network loading. A breakdown torque ratio of 2 supports use in equipment where resistance to short-term overload is expected and control over machine movement must be maintained.
Rated current of △ 400V 196 A and rated current of Y 690V 113.62 A give designers flexibility to choose the connection according to the power-distribution system. A power factor of 0.85 supports correct power-supply sizing and, together with efficiency of 95.1%, contributes to rational operation in production segments with long operating hours.
Applications for manufacturing, processing and logistics
The 3LC PRO 3LC-315L1-6 is suitable for the following operations:
- belt conveyors for dense materials
- process-water pumping stations
- cooling-tower fan units
- compressed-air compressor units
- mixing equipment in chemical production
- aggregate crushers in raw-material treatment plants
- extruders in plastics processing
- granulators in recycling lines
- rolling mills in light metallurgy
- winding machines in the paper industry
- centrifugal separators in food processing
- transport systems in automated warehouses
- agitators in fermentation tanks
Overview for installation and servicing without unnecessary downtime
When designing switchgear, cable glands 2-M63X1.5 simplify power routing and reduce complications during connection. DE bearing 6319-C3 and NDE bearing 6319-C3 are suitable for applications where long-term operational reliability and predictable service intervals are important. A noise level of 83 dB(A) corresponds to industrial use where performance is combined with control of operating conditions.
Package dimensions of 1412*727*1026 mm and a packaged weight of 974 kg are important when planning handling, storage and installation in production. When specifying the supply, you therefore have the information needed for logistics, lifting operations and receiving goods at the plant.
