• Manufacturer: Leroy-Somer (Nidec)
• Model series: LSA 49.1
• Frame size: M49.1M6
• Pole configuration: 4-pole
• Number of wires: 12-wire reconnectable, offering voltage flexibility.
• Power output:
  • At 60 Hz: 700 kW (875 kVA)
  • At 50 Hz (approx): For a similar model (LSA 49.1 M6 at 50 Hz), power is 750 kVA, or 600 kW.
• Excitation system: AREP (Auxiliary Winding) is typically included. Some configurations may use a Permanent Magnet Generator (PMG) or SHUNT system.
• Automatic Voltage Regulation (AVR): The AREP system uses an R450 or similar digital regulator.
• Voltage range: Reconnectable for a wide range of voltages, from 190V to 480V, depending on the winding connection.
• Insulation: Class H, for high-temperature resistance.
• Protection: Standard IP23 ingress protection.
• Winding pitch: 2/3 pitch winding, which helps minimize harmonic distortion.
