With combining the advantages of the hybrid excited synchronous machine and claw pole machine, hybrid excitation claw-pole synchronous machine (HECPSM) exhibits merits of controllable flux operation and independent flux paths. One novel wide range adaptive speed region control strategy is proposed in this paper, based on the analysis of the field control capability of HECPSM and the space vector control. Independent control methods of maximum torque per ampere (MTPA), space vector and minimum copper loss (MCL) control were employed for the proposed machine during three different speed regions in order to obtain satisfied performance in the whole speed range. The correctness and effectiveness of the proposed adaptive speed region control strategy and drive system design were verified by simulation and experimental results, which demonstrated that the proposed control strategy maximized the range of speed regulation while exhibiting the high efficiency.
