The design of electric turbochargers is a challenging task because it requires a suitable compromise between mechanical, output power and thermal characteristics. The present paper motivates the use of hysteresis motors in this high-speed application. This choice is driven by the high mechanical strength, elevated working temperature and output power density of the semi-hard magnetic materials that constitute the active part of hysteresis machines. An analysis is carried out with meaningful information extracted from the material properties, which is subsequently compared to the state-of-the-art machine technologies through the data available in literature. Since the followed approach is centered in the property analysis of semi-hard magnetic materials, the results are not related to any particular motor layout.
