Abstract: (Sponsored by TC 3) This webinar by Dr. Shuo Wang (UNNC) explores Synchronous Reluctance Motors (SynRM) with higher efficiency without rare-earth materials. The discussion begins with the core characteristics and advantages of SynRM, including its robust rotor construction, low cost, no demagnetization risk, and excellent load performance.
This webinar provides an overview of high-frequency signal injection techniques for the parameter identification of Synchronous Reluctance motor drives, with a particular focus on achieving maximum torque per ampere operation and sensorless control. The analysis examines the influence of key injection parameters, including the selection of injection frequency and the choice of injection axis in the dq reference frame. It is shown that the choice between d-axis and q-axis injection leads to different levels of flux distortion, torque ripple, and overall loss. The comparative assessment of these injection strategies is validated through simulation and experimental results, providing practical guidance for high-performance, efficiency-oriented motor control.
Finally, real‑world application scenarios are presented, including fans, pumps, compressors, and extruders. Case studies demonstrate that SynRM with advanced sensorless drives achieves significant energy savings over induction motors, offering a cost‑effective, maintenance‑friendly alternative to rare‑earth permanent magnet machines.
