1250 HP, 1800 RPM, NEMA Frame 7010, 2300/4000 V, TEFC

GE Motors is proud to introduce its new line of medium voltage totally enclosed fan-cooled (TEFC) induction motors called Quantum™ LMV. This motor was designed by a global engineering team yielding a motor for worldwide applications. Quantum LMV uses an innovative D-Duct heat transfer technology (patent pending). This unique internal structure allows for maximum airflow which leads to more motor output per frame size. The Quantum LMV also hasmore

Features & Benefits

  • Frame and rotor redesign increased motor output per frame
    A new D-duct system and rotor vents result in better temperature distribution throughout the motor.
  • Internal and external fan redesign
    New fans and fan covers offer dramatically improved airflow which results in improved heat transfer
  • Low Vibration
    The Quantum LMV was designed to have a large separation between the frame natural frequency and line frequencies, exceeding API standards, which offers solid mounting and a high degree of safety factor during the starting cycle.
  • Inverter Duty
    The Quantum LMV is designed for variable frequency drive (VFD) applications and strictly adhere to NEMA MG1 part 31 and IEEE-522.
  • Large AC Motors Meets API 541 4th Edition and API 547 for Petroleum and Chemical Applications
    Total electrical/mechanical run out levels meet stringent API standards, which translates to high motor uptime and an improved overall reliability. Efficiency and load are tested via IEEE-112 method
