Abstract
A generator has a stator which is provided with a multipole main winding and with an auxiliary winding, which is separate from and has the same number of poles as said main winding and a coil width not in excess of one-half of the pole pitch of said main winding. An exciter has a field-exciting winding. A controller is connected between said auxiliary winding and said field-exciting winding to energize the latter.
