What reading level is How to Build a One Half Horse Power Dynamo Or Motor book?
To quickly assess the difficulty of the text, read a short excerpt:
No. 26 wire (sixteen one-thousandths inch diameter) is wanted. Wind six and one-half layers, eight turns per layer for each half winding. "A", Figure 12, shows the arrangement in one slot. There will be 52 turns per segment. The current capacity will be two amperes.
Higher voltage should not be attempted in so small a ma- chine, as the excessive number of turns of wire introduces the insulation so many times as to reduce the amount of copper below its safe current-carrying capacity. An armature... would last so short a time as scarcely to repay the builder for his trouble.
Field Winding. In consequence of the round core of the field magnet, this winding can be quickly done in a lathe. Figure 13 shows a detail of a spool. It consists of three leatheroid or fiber discs four inches outside diameter, the two outer ones having a hole two and one-sixteenth inches diameter, the inner one two and one-eighth inches. A tin or other thin sheet metal tube, soldered along its lapped edge, and rolled with a small flange at the ends, holds the discs in position.
