PMG construction manual - Scoraig Wind

If the PMG is always used at higher speeds, it is better to use thicker wire, which can carry more current without getting so hot. Using thicker wire means there are fewer turns on the coils, which means that the PMG would not work at low speed. To use the same PMG for both low and high speeds, it is possible to change the connections.
