This study presents a simple sensorless algorithm based on the high-frequency signal injection for an interior permanent magnet synchronous motor. The sensorless drive using a square-wave-type injection signal has an enhanced control bandwidth and reduced acoustic noise owing to the reduction of filters and availability of high injection frequency. However, this method still needs discrete filters...
In-Wheel System is a high-efficiency system to supply a new concept of platform which raises the efficiency of motor drive system and applies it to an environment-friendly automobile by installing a highly efficient electric motor directly to wheels and removing factors of power train. In addition, this system receives a lot of favorable attention especially from various fields (e.g. electric vehicle,...
