A voltage propulsion drive coil assembly for a linear motor propulsion system for powering and propelling a magnetic levitation train in a track. The linear motor propulsion system includes at least one moving magnet assembly formed of a plurality of uniformly spaced pole ends with alternating magnetic polarity. The drive coil assembly includes a plurality of coils, each coil at least as long as the length of the magnet assembly and each coil at least as wide as the width of the magnet assembly. The coils and the magnet assembly are aligned lengthwise and arranged so that a constant number of coils is cut by magnetic flux lines at any given time. The coils comprise wire wound a predetermined number of turns. The number of turns in a coil is: (i) inversely proportional to the speed the train is expected to travel at that point on the track and (ii) directly proportional to the force required to propel the train at that point on the track.
