Web12 de jan. de 2024 · A high-frequency (HF) mathematical model of a PMSM with an ISF is established. Based on the presented HF model, the HF responses of the PMSM with various severity of ISF under HF voltage injection are analyzed in detail, where both the short-circuit ratio and the fault resistance are considered to evaluate the fault severity. Web18 de set. de 2014 · Abstract: High-frequency injection (HFI) is an alternative method to estimate permanent magnet synchronous motor (PMSM) rotor position using magnetic saliency. Once the maximum fundamental electrical frequency and the power converter switching frequency are set, the HFI voltage amplitude tuning is generally based on trial … WebMethods based on high-frequency signal injection are commonly used for rotor position estimation of PMSM operating in low speed (including standstill) state. Signals injected mainly include rotating high-frequency voltage and pulsating high-frequency voltage, and the latter has a relatively wider application range [13, 14]. in a megger controlling torque is provided by
