Portal Point Generator

Back to overview

An efficient and compact generator that can be coupled with wind turbines or water wheels to produce upwards of 100W

I would recommend to go for lower AWG, 18-20, that would reduce the resistive and heating losses as well as reduces the breaking effect when connected to a load. this should allow the turbine to pick up speed, and give you a decent current output, without the need to step down the voltage

Hi Vijay !
And thank you for sharing and documenting your project ^^

Because the V2 is not finished yet, i plan to realize your generator V1 to test it on my Savonius
I can got easily all the components, but for realisation, but I've two questions :
• To do very precise job on coils, how many turn of the 30 AWG wire have to be done ?
• The enamel copper wire is sell by weight, so, how many weight is necessary to make the 6 coils ?

And bonus question, with time passed and experience acquired, for optimizing the V1, would you still use 30 AWG wire ? In case of not, what AWG of wire  and number of turn do you recommend ?

Good luck for V2 ^^

Hi Vijay

I finaly realized the generator, and  for my needs, make somes modifications in the 3Ddesign and electrical parts.

Brilliant Work! i'm going to post a log about this!
