This is my first first step to build my own wind power generator.

A 3-phase 1.5kW ASEA (1400-1700 RPM) squirrel cage motor have been capacitor coupled to allowing the rotor to be temporarly magnetized, and therefore working as a 1-phase generator around nominal rotation speed.

The motor is B3-connected to a 5,3:1-gear assembly.
This 'generator' was then connected to a mill cutter with variable speed to test the function and output of the generator.

In this video the millcutter was running at 262 rpm (well within the rotational speed of the oncoming blades).
The blades will be fabricated in wood, but if that doesnt work properly, glass fiber-composite blades will be bought online.

To calculate the proper dimensions and rpm of the blades,

was used.
