    Abstract Permanent magnet (PM) machines are considered the most suitable machine type for very high-speed applications. Still, due to the growing demand for ever higher rotational speeds, PM machines are approaching their limits. The focus of this paper are dierent factors that lie behind inherent speed limitations of permanent magnet machines. The limits - thermal, elastic and rotordynamical - are defined, classified and correlated to basic machine parameters.
