wind turbine model
« on: June 30, 2020, 11:49:42 AM »
I've found some neat solar powered wind-turbines from China - if I remove the large base/solar receiver do you think I'll be able to connect standard DC supply to drive the units? I assume it will only need a few volts?They only cost 12 each compared to 30-50 for a powered German model?

Likely yes.   As to how many volts, you'll have to see when you get one, but unlikely to be overly fussy, will just run stupidly fast on too many volts.   

( The idea of a solar powered wind turbine makes me giggle.  ).

 :thankyousign:
at n gauge the turbine model converts to approx 150' high (30cm) so may work out  well and at low voltage (hopefully) will turn slowly to scale? Wish me luck :laugh:

I'm no expert, but my thoughts are that the voltage required to run the motor for a scale turbine speed may be too small for it to move at all.  I would be inclined to look at some mechanical gearing to reduce the RPM perhaps?

Ooooh a good kit-bash project..   

First, remove the power supply (solar cells) and replaced with a DC controller.
Next, replace motor with a geared on to drive the blades.
Then replace the tower to house the new motor. 
And finally, replace the blades with better shapes. 

That should just about do it.

Sounds like Grandad's broom - the same broom that he'd had and used for 37 years.
In that time it had fifteen new heads and 7 new handles, but it was still the same broom - well, it still had the same nail  :D

I don't think Trigger referred to the same nail - IIRC his "evidence" for it being the same broom was an old photo of him holding it and the broom itself at the time he was telling the story.

Hi There,

I have a windmill on a hill on my layout ( unsurprisingly named Windmill Hill  :D) and I have one of these motors in it .....

https://www.ebay.co.uk/itm/DC3V-9V-5V-6V-5RPM-Slow-Speed-Reduction-Mini-300-Turbo-Worm-Gear-Motor-Robot-Toy/253263644637?hash=item3af7b087dd:g:4KMAAOSwUDZchyMW

so cheap I bought 6, and I run it on 3v which give a very realistic speed for the mill.

All best wishes

Kevin
