IEEJ Transactions on Electrical and Electronic Engineering   8 87-93   Jan 2013   [Refereed]
This paper presents a new signal injection method without torque ripple for sensorless controls of salient-pole synchronous motors at low speeds. At low speeds, since the back electromotive force (EMF) including position information decreases, add...

AIP Conference Proceedings   1865    Jul 2017
© 2017 Author(s). This study presents a new method of current controls of PMSMs (Permanent Magnet Synchronous Motors) based on a maximum torque control reference frame, which is suitable for high-performance controls of the PMSMs. As the issues of...
