An electrical machine utilizes a consequent pole rotor with a polyphase stator assembly and a control coil to produce a widely variable voltage output. Either constant-speed-variable-voltage performance, or variable-speed-constant-voltage performance may be easily achieved by varying the magnitude and level of D.C. current supplied to the control coil. Single and double rotor embodiments are disclosed, with cogging being easily suppressible in the double rotor embodiments.
