This paper presents principle and basic characteristics of a novel linear synchronous motor based on "half-wave rectified self excitation principle". The field winding is short circuited through a diode and the armature winding is conventional 3-pahase windings. If the amplitude of the balanced 3-phase currents is modulated by an alternating wave with bias frequency, the produced magnetomotive force pulsates at bias frequency and moves at synchronous velocity. This pulsating magnetomotive force induces the electromotive force with bias frequency in the field winding. The field excitation is obtained by rectifying the electromotive force with the diode of the field winding. In this paper, we design and build the experimental machine and confirm the basic characteristics. We also deduce the performance equations and investigate on the thrust ripple reduction.
