Permanent Magnet Generator QUESTION What kind of mounting options can you propose ? ANSWER Machine with bearings & housing : Floating mounting Foot or Flange mounting Machine without bearings Rotor and Stator fitted

Permanent Magnet Generator QUESTION Most PMG used Alnico magnets. Why should Earth Rare magnets solution be better ? Rare Earth magnets, type Nd - Fe- Bor, are stable, with a high coercitive magnetic field, high energy. Consequently, we have a lower volume for the same power. Rare Earth Magnets advantage ? The necessary passport for reliable, and compact design.

Permanent Magnet Generator QUESTION What kind of additional options can you propose ? ANSWER We propose a wide range of electrical & mechanical options. Currently our customers focus on : - double frequency winding : typically 50 Hz & 60 Hz - thermal capacity at a temperature : up to -55°C Customer key target : one standard PMG for all applications
