Permanent magnet – GDG Series

GDG Series

Special Permanent Motor Design perfect for vertical axis wind turbines, with the following main characteristics :

  • Torque patent technology: thanks to the newest “Precise Coil” technology, no hysteresis and very low starting torque (<1Nm);
  • Original structure: very compact design;
  • Perfect for low speed applications, no gearbox needed, direct drive;
  • High standard quality components, for use in extreme environments;
  • Low energy loss, low mechanical resistance, high efficiency;
  • High heat dissipation due the aluminum alloy outer case and special internal structure.
