Low Voltage Generators for Industrial Applications

  • Number of poles: 4 poles
  • Power ranges:
    15-3125 kVA @ 400V / 50Hz / 1500rpm
    19-3750 kVA @ 480V / 60Hz / 1800rpm

  • Insulation class H
  • Temperature rise class H
  • Rated supply voltage
    50 Hz: 380 - 440 V (Y). 220 - 254 (Δ)
    60 Hz: 380 - 480 V (Y). 220 - 277 (Δ)
    For frame size 180-355 YY and ΔΔ (with 12 leads) and single phase operation with single phase rating are available.
  • Winding and impregnation
    2/3 winding pitch to minimize the 3rd harmonic of line to neutral voltage (L-N). Generators are optimized to ensure very low levels of voltage (line-to-line and line-to-neutral) waveform distortion.
    All windings are vacuum pressure impregnated with high quality polyester-imide resin. Windings withstand all expected mechanical and electrical shocks and vibrations as well as chemicals.
  • Excitation and regulation
    Brushless excitation, built-in AVR, self-excited PMI (Permanent Magnet Insertion) ensures the voltage build up, auxiliary winding for excitation power supply.PMG is avaliable for AMG 0200 to AMG 0500.
    Sustained short circuit current: >3 x In, 10 sec.
