WINDMILL EXPERIMENTAL PATTERNS AND PLANS TO SIZE Private
worksheets for prototype experiments. Plans are sideways in
inches. June 29th., 2001by Ray Auxillou, TRUSTEE and Project
Director, the BELIZE DEVELOPMENT TRUST. SIDE VIEW OF WINDMILL
WITH CORRECT HEIGHT for a small battery charger d.c. motor
Construction using aluminum. This windmill on location in the
Tyrol of Europe is a bigger one than the plan here, which is
intended for the back stern rail of a 30 ft sailboat as a small
battery charger. (a) On the motor. A.C. is better than D.C.
because you can run a longer distance with A.C. The higher the
A.C. voltage the further you can go in distance with a line. (b)
The number of poles in a generator indicate the number of rpm
necessary. For example: a 2 pole is 3600 rpm, a 4 pole is 1800
rpm, and a 6 pole a.c. generator would be 1200 rpm. (c) The
higher the cycles, the smaller the wire. A high cycles would
mean a smaller generator. But the rpm would go up also.
Necessitating a bigger reduction gear. (d) Tax I
