Existing derating schemes typically restrict torque or current in response to thermal rise or rely on complex model-predictive controllers. The proposed AAC method directly regulates rotor speed and acceleration, offering a simple and effective means to ensure safe operation under thermal and mechanical constraints. The AMEBA (A Mechanically Based Antenna) six-phase PMSM, developed in-house, serves as the laboratory platform for initial validation. An experimental setup has been implemented to verify the algorithm, and detailed simulation and experimental results will be presented in the full paper. The study also introduces a newly designed interior PMSM (IPMSM) prototype that employs a rare-earth-free rotor with carbon-fiber wrapping. While the carbon sleeve enhances mechanical strength and high-speed capability, it also raises challenges related to rotor stress, acceleration-induced forces, and thermal management. Excessive heating may result in demagnetization of the magnet, thereby reducing its reliability and performance. Future work will extend the AAC framework to incorporate rotor stress and magnet temperature, enabling integrated thermal–mechanical protection.
