Design Considerations for High Surface-Speed and High-Load Switched Reluctance Machines
This thesis investigates and determines the design considerations to be addressed when designing switched reluctance machines (SRMs) operating at high surface-speeds and high-loads. A new method is introduced to the traditional machine design procedure that captures all of the mechanical, thermal …

Fast transfer path analysis using controlled electric motors as in-situ blocked force vibration sources
Under certain driving and road conditions, steering manoeuvres may provoke audible noise inside the vehicle compartment induced by the electric power steering (EPS) system. Regarding noise, vibration and harshness (NVH), engineers require practical tools to assess, design and troubleshoot steering …
