3-Phase motor turned into 1-phase home made wind power generator

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.

Ordinary motor run capacitors in a 2C-1C config:

"Motor AC capacitor 30 µF 475 VAC"

The proper capacitance with this "2C-1C"-method is about 60µF/kW to 80µF/kW.

It is in theory possible to get 80% out of the peak power, but increasing the RPM yields even more, so with a slight overspeed, over 1.5kW is possible!

You are welcome to PM me for the electrical drawing, cause youtube wont publish it (?)

this 2c-1cconfig.,this 2c is this the capacitor with mark 2C or is it two capacitors conected togeather,i have 3 phase ac motor and i want to convert it to single phase generator,how to wire that motor

[tehatemachine]

@Bcroft39 you don't. You have to buy a phase converter, which is basically another electric motor that uses a single phase and converts it to three.

I have a 3 phase motor on a table saw I recently purchase pretty cheap but I'm not wired for 3 phase. How can I convert it to single phase?

[andranik12]

could u tell me what type of capacitor you used or what type i would need per kw

are you geting 1.5kw's ???

do you get the power from the same wires you normoly would give power to get the motor working???

could u also tell me how you wire the capacitor together??

thanks in advance

bra jobbat!
