Abstract: The present invention relates to a two-phase, two-column linear pulse motor propulsion system, and more particularly to a two-phase, two-column linear pulse motor propulsion system which can implement high-speed driving, stopping, and switching directions forward/backward through non-adhesive driving characteristics by improving accelerating performance and torque performance.The two-phase, two-column linear pulse motor propulsion system comprises a field unit 121, 122 prepared in two columns in the longitudinal direction under a moving body 110 so as to generate a magnetic field; an armature unit 131, 132 which is prepared on a travelling track, generates a shifting field by the power supplied from a power conversion device, is prepared in two columns so as to correspond to the two-column field unit 121, 122 and generates the propulsion force of the moving body 110 through interaction due to a two-phase synchronous signal. Thus, it can improve propulsion force and acceleration/deceleration performance, compared to a linear propulsion system with one phase.
