IEEJ Transactions on Industry Applications   132(8) 842-848   Aug 2012
Permanent magnets made of rare earth materials are used in interior permanent magnet synchronous motors (IPMSMs), which are major component of hybrid electric vehicles. The recent remarkable increase in the cost of rare earth materials is a major ...
TAGAMI Kotaro, OGASAWARA Satoshi
IEEJ Transactions on Industry Applications   132(7) 709-717   Jul 2012
Advances in power semiconductor devices have contributed to the realization of high-performance power converters and high-precision motor positioning. However, high-speed switching of power devices lead to a high-frequency leakage current and/or e...
OGASAWARA Satoshi, KUROKAWA Hiroyuki, AKAGI Hirofumi
IEEJ Transactions on Industry Applications   123(6) 667-674   Jun 2003
This paper proposes a new circuit configuration for a position-sensorless drive system using an interior permanent magnet synchronous motor (IPM motor) rated at 3.7kW. The configuration can decrease the number of the sample and hold circuits to fo...
