775 Motor based Dynamo

Jasonb:
The intension was to write it up for Model Engineer Mag, but as there have been a few changes there I will have to see if it goes there or just on the web.

I'll try and remember you when the 2D drawings are done.

mikehinz:
Jason, thanks very much!  if your build is published, let me know when.  And of course if you do make the drawings available, I'd very much appreciate them!

Jason,

That is a very nice looking motor to dynamo conversion.

What was the overall length of the motor you used?

Chuck

Jasonb:
Sizes below which seem fairly standard but best to pull your chosen motor apart and check before making parts.

Couple of sectional views which should show what is going on. The pockets either end take the bearings stripped from the motor but not drawn. Brushes are in their "relaxed" position hence they are not resting on the comutor. The notches in the square insulators stop the brushes from rotating when they are put under spring pressure.

kuhncw:
Jason,

Thank you for sharing the section views and motor specs. 

Your dynamo makes a great project. Let us know when it is published.
