Impact of machine magnetization state on permanent magnet losses in permanent magnet synchronous machines [PDF]

open access: yes2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017
Permanent magnet synchronous machines (PMSMs) operation above based speed is typically achieved by injecting negative d-axis current to produce flux weakening. However, this increases permanent magnet (PM) losses, reducing therefore the machine efficiency.
