Electric motor 132 kW, 990 rpm, 400 V / 690 V, 4LC-315L2-6 LV

Irregular drive operation, unnecessary losses and higher maintenance demands can slow down the entire line, especially when operation is required in the 900-1000 rpm range. That is precisely why the 4LC-315L2-6 with an output of 132 kW is designed to deliver balanced performance, efficiency and reserve for stable industrial operation in this speed class. It uses a well thought out construction with advanced materials and sophisticated windings that help maintain long term reliability even under higher load.

Energy efficient operation in the 900-1000 rpm speed class

This 6 pole electric motor is suitable where smooth starting, precisely controlled operation and good load resistance are required. At the rated speed of 990 rpm it achieves 96 % efficiency and a power factor of 0.86, which helps reduce energy losses in long term use. In practice, this is a solution that fits well into modernisations where a return is expected through higher efficiency and lower thermal stress.

Construction ready for industrial load

The 315 mm frame size provides a solid foundation for use in production units where mechanical stability and consistent output are decisive. The rated current of the delta 400 V connection is 231 A and the rated current of the star 690 V connection reaches 133.9 A, so the motor can be flexibly adapted to the site’s power supply system. The rotor inertia of 6.9 kg*m² supports smooth starting and good dynamics in applications where torque control is important.

Operating data that make drive design easier

• The starting torque ratio Tst/Tn of 1.6 supports starting in applications with a slightly higher load capacity.
• The pull-out torque ratio Tmax/Tn of 2 provides the necessary reserve when the load changes.
• The starting current ratio Ist/In of 8 is important when designing the network and starting the motor.
• The noise level of 83 dB(A) allows better assessment of acoustic conditions in the production area.
• DE bearing 6319-C3 and NDE bearing 6319-C3 contribute to reliable bearing support.
• Accessories with 3 PTC thermistors help monitor the temperature condition of the winding.

Connection to low voltage systems without unnecessary compromises

The motor is ready for use in low voltage infrastructure and in projects where precise electrical design is important. The 2-M63X1.5 cable glands make installation and cable organisation easier, which will be appreciated by technology suppliers and service teams when replacing older drives. A packed weight of 1069 kg and packed dimensions of 1412*727*1026 mm are important details when planning handling, transport and installation space.

Use in production operations with demanding requirements

• Pumps benefit from stable speed and torque reserve during long term media transfer.
• Fans use smooth operation and efficiency that supports energy efficient running.
• Compressors gain a reliable foundation for continuous load in air technologies.
• Conveyor lines benefit from smooth start up and consistent output under repeated load.
• Mixing and processing equipment uses a good torque reserve as resistance changes.
• Heavy industry will appreciate a design suitable for drives for light and heavy industry in demanding operations.

If you are modernising a drive and looking for a solution with an emphasis on energy efficient and reliable operation, this IE4 electric motor offers a suitable technical basis for long term use. VYBO Electric draws on its own development and experience, which is reflected in premium materials and stable running, so it is worth requesting a quotation for your specific project.
