Raising the turbine

[Otto]

Although I do not have my batteries yet, and while the weather is good,I would like to raise my 50' tower with my DC turbine motor.  I know that the turbine should not be allowed to free spin without a load so I am asking for suggestions as to what I can connect this to until I get my battery bank set up.  This could be in a few days or a few weeks.  I am waiting on someone else for these batteries and unsure when this is going to take place.  As always any help is appreciated.

Thank you,

Otto

 Bring your wire,s down the tower and short them

out.

You can run the wires down the tower and just short them together at the bottom.

However, make sure it is not rotating much especially in high winds. If it is, then the blade may be stronger than the alternator and if that is the case, it will burn out the alternator. It will rotate very slowly when shorted but it should not turn more than a few RPM.

Have FUN!

Otto-

My first turbine was made from a DC electric motor. It would spin if I had the fields shorted or not.

1. You might try to tie the blade to the tower and use a slip knot so you can give it a yank and the rope will fall free.
   
2. Install some type of braking mechanism that can be released at ground level. There have been several mensioned on this site. Harrie and Flux comes to mind.
   
3. A large resistor might also work at ground level, but the turbine would continue spinning.
   
   

Hope this helps

I connect my little ametek genny to the element of an electric space heater while I'm fiddling with the battery bank via a DPDT bayonet switch.

It almost acts like it's shorted out, but any heat has somewhere to go rather than being dissipated inside the motor/PMA if indeed that's what happens to unused current.....

Hi Otto

 Glad to hear your making progress.

 What did you settle on for the motor and blades.

 Good luck to ya and make sure to have an Erection party.:>)

Hi Vawtman, since this is my first wind turbine I made it from a 130 volt 18 amp 3250rpm DC motor.  The blades are made out of PVC.  It is up and spinning.  I have a 12 volt car defroster/heater connected at the base.  I hope to get my batteries soon.  I have searched all over this site for information on a how to wire up the DC generator to the diode, switch, dump controller, fuses and battery bank with no success.  Would you happen to know where I can find out this information? I also need to know,what amp fuse and do I continue to use the same size wire throughout the rest of the system?

Thanks,

Otto

Yea i like the heater idea. at leased u get to see the power going to some kinda use.

the wire depends on distance/volts/current. what size wire are you using and how far does it have to travel?

Hi Otto

 The first thing to do is test the open circuit voltage( no load) in a reasonable wind.

 If you did that, What were the readings?
