Use it with care, though.  I found a mistake on the very first page I looked
at.  Under "motor relationships", single phase amps knowing kW, should be
(kW * 1000) / (E * PF).

For the question I'm pondering : Does anyone know how to increase the
no-load speed of a parallel-wound DC motor without rewinding or changing the
supply voltage ?  ISTR there was a way to do it, but I don't remember what
it was and I can't find my old motor theory book.
