Investigation of saliency in a switched-flux permanent-magnet machine using high-frequency signal injection
journal contribution
posted on 2017-09-12, 09:57 authored by Tzu-Chi Lin, L.M. Gong, J.M. Liu, Zi-Qiang ZhuIn order to facilitate the selection ofmachine whether
it is suitable for high-frequency (HF)-signal injection-based sensorless
control or not, this paper proposes a complete experimental
investigation method for the analysis and validation of machine
saliency level, including primary saliency, which is essential for
HF injection-based sensorless control, and the secondary saliency,
which will deteriorate the rotor-position estimation. The experimental
results obtained on a new type of switched-flux permanent-
magnet (SFPM) machine prove that with identified primary
saliency, the accurate rotor-position estimation can be achieved,
and with small secondary saliency, the estimation will not be deteriorated
much in the SFPM machine. The conclusion is verified by
the experiments based on the HF pulsating signal injection-based
sensorless control at zero and low speeds.
