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