A line-start permanent-magnet synchronous motor (LSPMM) consists of a stator with symmetrical three-phase armature windings and a salient pole rotor with a permanent magnet for excitation and a starting winding similar to the squirrel-cage winding of an induction motor. In this paper, a general analytical method based on tensor analysis is proposed for practical performance calculation of a three-phase LSPMM. The general equation for the currents of the three-phase LSPMM is derived from the transient impedance tensor expressed in polyphase symmetry axes, and the general equation for vibratory and nonvibratory torques is derived from the current equation.
