EOLIC GENERATOR¦S WINDING

[petronila]

Dear All,

Are the eolic generator´s windings special type?

Did need special Materials like the Inverter duty Wires?

Some guidelines in order to rewind it?

Some good experience to share with this repairs??

Thanks for Inputs.

For wound rotor motors with electronic connection and disconnection through the rotor winding, high voltage spikes are generated in the windings. Therefore in my opinion similar techniques as those for inverter duty motors must be considered. The rotor winding banding and support of the terminal leads should be carefully evaluated.
The bearings could be affected by high frequency capacitive discharge currents, developing flute. Insulate the bearing housings but add a grounding shaft path to prevent bearing circulating currents. Due to high frequency insulated bearing still have capacitive coupled currents, for that reason the shaft grounding device is still required.
