Development of interior permanent magnet motors reducing harmonic iron losses under field weakening control In this paper, we present the development of interior magnet motors reducing iron loss at high rotational speed under the flux weakening control. The rotor... K Yamazaki,S Ohki,A Nezu,... ...
In this study, we investigate the demagnetization resistance of a concentrated winding IPMSM (interior permanent magnet synchronous motor) accounting for field weakening control by changing the magnetization direction of the permanent magnet under a high-temperature environment. IPMSMs are investigated by ...
