摘要
This paper proposes a new method for properly estimating the rotor initial phase (i.e., the position) of the newly emerging self-excited hybrid-field synchronous motors (SelE-HFSMs), which have the rotor held by both a permanent magnet and a diode-shorted held winding. The proposed method injects a spatially rotating high-frequency voltage and detects the rotor phase directly by evaluating the norm of the associated current. The method is very simple, hut has a high degree of usability.
