An excitation control scheme for a two-axis excited synchronous motor is described, which, by the direct connection of the quadrature field winding and the armature circuit through a diode bridge rectifier, enables the motor power factor to be maintained at approximately unity, irrespective of load. The steady-state performance based on a simple phasor diagram is verified by experimental results.
