要約(英語): This paper describes permanent magnet synchronous motors by having the characteristics of a bonded magnet. In general, most PMSMs use a Nd-Fe-B sintered magnet. Because the Nd-Fe-B sintered magnet has a high magnetic energy, it is possible to obtain high torque and high output power. On the other hand, the magnetic energy of the bonded magnet is lower than that of the Nd-Fe-B sintered magnet. However, this magnet has a higher permeability than the Nd-Fe-B sintered magnet and the eddy current is negligible. It is found that flux weakening control is useful because of the high permeability. This paper presents experimental results that verify the usability of the bonded magnet machines.
