Abstract
A combined alternator-compressor including a brushless excitation structure for the alternator. The magnetic flux field for the alternator is generated by a rotating permanent magnet ring structure and a stationary toroidal control coil which is arranged concentrically with and between the rotating permanent magnet ring and an alternator base. The control coil is mounted in additive and subtractive magnetic relationship with the permanent magnet ring for control of the magnetomotive excitation field of the alternator.
