Sensorless drive of surface-mounted permanent-magnet motor by high-frequency signal injection based on magnetic saliency
TL;DR: In this paper, a sensorless control scheme of a surface-mounted permanent magnet (SMPM) motor using high-frequency voltage signal injection method based on the highfrequency impedance difference is presented.
Journal ArticleDOI
Analysis of permanent magnet machine for sensorless control based on high frequency signal injection
TL;DR: In this article, a simplified high-frequency model of an SMPM machine in the estimated rotor reference frame is developed and a sensorless rotor position and speed estimation algorithm is described.
Journal ArticleDOI
Comparison of PM Motor Structures and Sensorless Control Techniques for Zero-Speed Rotor Position Detection
TL;DR: In this article, the rotor position of a synchronous permanent magnet (PM) motor can be detected by means of the injection of a high-frequency stator voltage superimposed to the fundamental component.
Proceedings ArticleDOI

TL;DR: In this paper, the authors present a complete design methodology for the sensorless vector control of permanent magnet synchronous machine (PMSM) motor drives in fan-type applications, which is built over a linear asymptotic state observer used to estimate the PMSM back-EMF, and a novel tracking controller based on phase-locked loop (PLL) system, which by synchronizing the estimated and actual d-q frames estimates the rotor speed and position.
Proceedings ArticleDOI
Advantages of inset PM machines for zero-speed sensorless position detection
TL;DR: In this paper, the rotor position of a synchronous Permanent Magnet (PM) motor with anisotropic rotor can be detected by the control system which superimposes a high?frequency signal to the steady?state stator voltage.
