Comparison of Induction and Synchronous Reluctance Machine Based Actuators for Elevated Temperature Environments.

This paper compares the designs of an induction and a synchronous reluctance machine-based actuator for use in an elevated-temperature environment application and compares their dynamic and loss performances: The dynamic requirements of the application must be met, while the low permissible overtemperature of the windings calls for minimum loss designs, all within a certain limited available volume. The comparison is done both theoretically, using semianalytic models, and experimentally, with realized prototype machines. The uncertainties introduced by the manufacturing process are also considered and their influences on the final products’ performances investigated. [ABSTRACT FROM PUBLISHER]
