基于搜索线圈的全速域内嵌式永磁同步电机转子位置检测

Using the search coil to provide the backup rotor position for the interior permanent magnet synchronous motor (IPMSM) can improve its operational reliability and prevent equipment damage. This article proposes a rotor position detection method for the IPMSM based on the search coil in the full-speed range. Make the search coil into the flexible printed circuit (FPC) and stick it on the top of the...
