GFA series Coreless Permanent Magnet Axial Flux Generators have been designed starting from the needs of small wind generators and later, seen the excellent performances, has been used in a wide variety of applications, where small dimensions and weight are crucial. GFA generators have very good efficiency, due to their double rotor equipped with rare earth (Nd-Fe-B) magnets and the small gap betweern stator and rotors.
Their particular construction technique, almost totally in aluminum, determines limited size and weight.

Coreless axial flux technology reduces to 0 the starting torque, optimasing the transformation of mechanical energy into electricity.

GFA generators are available with different stators and poles number to meet the needs of different RPM and powers.
Green Line can design and develop axial flux generators based on specific customer needs even for small quantities.
