GES 120 Alternators

GES 120 Alternators

Moog's GES 120 series alternators are designed to meet the application requirements of manufacturers of small size wind and hydraulic turbines. These synchronous alternators with rare-earth high polarity permanent magnets, are characterized by a higher yield and a reduced weight compared to the more traditional asynchronous alternator solution.

Benefits

  • Excellent weight / power ratio
  • Elevated ouput
  • Low maintenance
  • Encapsulated windings for safe and long lasting operation
  • Outer shell made of aluminum or steel suitable for all weather conditions
  • Frameless version can be integrated directly in your own mechanics

The ratings shown are referred to the following conditions:  Environmental temperature: -25 ° + 40 ° C (for higher temperatures a performance "derating" can be expected). Altitude not exceeding 1000 m from sea level (for higher altitudes a performance "derating" can be expected). Power output at the alternator terminals with P.F. = 1. Alternator reached by a flow of air at about 8 - 10 m/sec.
