Description
そのため、センサレス駆動時に回転子の位置を高精度に検出することができる永久磁石式回転電機を得ることができる。
まず、図1を参照しながら、永久磁石式回転電機のセンサレス駆動時における磁極位置の検出方法について説明する。図1は、永久磁石式回転電機の磁極位置の検出方法を示す一般的な説明図である。図1において、永久磁石式回転電機には、磁極位置検出用の高周波電圧が重畳された駆動電圧が印加され、測定された各相電流の電流波形を処理することによって、磁極位置が推定される。
そのため、センサレス駆動時に回転子の位置を高精度に検出することができる永久磁石式回転電機を得ることができる。
図12は、この発明の実施の形態2に係る永久磁石式回転電機の構造を示す断面図である。図12において、回転子20の外半径をR0とし、回転子20表面の曲率半径をR1とすると、R0およびR1を、R0>R1となるように設定している。
