Design of a 5-phase multilayer winding motor drive for a fault-tolerant testbench environment

This thesis focuses into the design and analysis of a 5-phase synchronous permanent magnet (PM) motor featuring 20 slots and 18 poles. The motor incorporates a fractional slot concentrated winding (FSCW) configuration with four layers, strategically chosen to mitigate unwanted magnetomotive force (MMF) harmonics. The study encompasses detailed design considerations, including the selection of the winding configuration and layering, to achieve optimal performance. Additionally, a comprehensive machine control strategy is implemented to facilitate the motor's operation in both normal and faulty modes. Through simulations and analyses, this research explores the impact of the chosen design parameters on the motor's performance, fault tolerance, and capability. The presented findings contribute valuable insights into the integration of winding configurations and control strategies for enhancing the robustness of synchronous PM motors in practical applications.
