1. A linear propulsion system comprising:

  • a track comprising a first plurality of stator sections and a second plurality of stator sections, the second plurality interleaved between the first plurality, each stator section including frame and a plurality of coils mounted on the frame, each stator section having an activated state and a deactivated state;

    a vehicle;

    a mover functionally mounted to the vehicle and disposed adjacent to the track, the mover including a plurality of magnets; and

    a dual inverter system operably connected to each of the stator sections, the dual inverter system including;

    first and second multi-phase inverters, the first inverter operably connected to the first plurality of stator sections, the second inverter operably connected to the second plurality of stator sections; and

    a controller operably connected to the first and second multi-phase inverters,wherein a propulsion force on the vehicle is generated when the mover is adjacent to one or more of the stator sections in the activated state.
