Abstract :
AC excitation schemes of a brushless self-excited type three-phase synchronous machine are presented. The rotor field winding of the machine is short-circuited with the diode, and an exciter or other exciting equipment is not required in this machine. The two excitation schemes proposed have the advantage of reducing the torque ripple as compared to the scheme which superimposes a singular rotating field with different speeds from the positive-phase-sequence field. This confirmed by the simulation. Experimental results are also given.<>
