In Halbach machines, the potential demagnetization of permanent magnets (PMs) should be considered to avoid irreversible demagnetization (ID). In this paper, the Halbach machines with air- and ...

Permanent magnet synchronous machines (PMSMs) have been widely used in many industrial applications due to their superior performance. Under normal operating conditions, the permanent magnets (PM) ...
