Parallel hybrid excitation alternators (PHEAs) are large in size but offers wide flux regulation capability. Series hybrid excitation alternator has limited flux regulation capability but compact compared to PHEAs. A new rotor excitation topology has been proposed for a series hybrid rotor excitation alternator (SHREA). The proposed machine is not only small in size but also have wide flux regulation capability. The proposed machine can be classified as a series hybrid machine as permanent magnets and field windings are arranged in a single rotor ensuring series addition of permanent magnet flux and field winding flux. In this study, one more rotor configuration for quick maintenance SHREA is also proposed. As the name suggests, for any fault in excitation winding, they can be easily replaced. Two 1.3 kW prototypes with such designs have been validated with finite-element method simulation and hardware testing.
