 748).Pidgeon machines possess fixed inductors arranged in a manner that increases the electrical induction effect (and it electrical output is at least double that of typical machines of this type [except when it is overtaxed]).The essential features of the Pidgeon machine are, one, the combination of the rotating support and the fixed support for inducing charge, and, two, the improved insulation of all parts of the machine (but more especially of the generator's carriers).
