“Testing the windmill at 5 Bft . Results till now OK , Rpm stays around 300 , Amps 20 ,Volt 30 . Electronic system doing good .”
“The actuator is made of a battery-screwdriver with a threaded rod m6 and a travelling nut , distance adjustable with micro-switches. The blade-angle can be controlled by Rpm ,Manual, and anemometer with a micro-controller. A generator can be connected with a timing-belt or co-axial with your design (which I made before succesfully). It’s not for beginners ,but I like mechanical-engineering.”
Below is an older concept for control by servo on the tail.
” The tail is moving by a small actuator ( as used for adjustment hospital beds).
The generator is made according to your design and it has an electrical break , double safe . The rotor of 10ft has a lot of extra power . And I see sometimes burned stators on Internet (Alan) I decided so.”
additional information addes 24th August:
“My findings : In high wind there is a direct effect to a lower constant rpm 300 .
I can hear a low noise level of stall in high wind.
Nice load current 20 – 25 amps.
The electronical circuit board can be more compact .It takes 400 millies max.
An LCD readout is preferred.
Waiting for more wind .
