Identification of parameters of single-phase PM synchronous motor

Utilization of Finite Elements Programs and Matlab Simulink in the Study of a Special Electrical Motor

“…In order to obtain starting torque different design solutions are used: the realization of pole shoes with some notches or achieving a tapered air gap, the utilization of the rotor with some additional permanent magnets (parking magnets) [1], [2], [4], [9]; all these constructive solutions in order to impose to the rotor a preset rest position, so the PM magnetic field axis to be unaligned with the axis of stator winding. This paper will refer to such motor, with tapered air gap, Ushaped magnetic circuit and PM rotor, and it completes the study presented in [5]. Fig.1a shows the cross section of the motor and Fig.…”
