This paper discusses the design process of permanent-magnet-free ac machine-based actuators working in elevated-temperature environments for high-dynamic applications. Both demands given by the application with respect to maximum volume, torque-over-speed performance, and the thermal limits of the insulation materials, which limit the maximal loss that may occur, have to be considered. Starting from...
This paper presents an induction and a synchronous reluctance machine-based actuator designed for use in an elevated-temperature environment application and compares their dynamic and loss performances. In the design process, semi-analytic models and suitable controller designs are implemented in a genetic algorithm to develop minimum-loss designs. Simulations and measurements are used to compare...
