A transformer having a transformer core that forms a magnetic flux path between and through a top yoke, leg, and bottom yoke of the transformer core. A winding can be disposed about the leg. Further, a flitch plate, which can have at least one slot that is configured to reduce eddy losses generated by the winding, can be disposed adjacent to the leg and extend between the top yoke and the bottom yoke. The flitch plate can be clamped to the top and bottom yokes by top and bottom clamps, respectively. The top and bottom clamps can each include at least one cutout that reduces an attraction of stray flux from the winding and into the corresponding top and bottom clamps. Additionally, at least one of the top clamp and the bottom clamp can include an internal lattice structure.

An EM driver for accelerating an object may be configured as an EM rifle for accelerating, rotating to spin-stabilize, and releasing a projectile. A core includes a stator coil, forward and reverse coils, a railed shaft, and a transfer shaft. The stator coil generates a first EM field, and the forward and reverse coils generate second and third EM fields which interact with the first EM field to accelerate the armature in forward and reverse directions, respectively. The railed shaft is elongated along a central axis through the armature and includes multiple rails arranged helically around a central shaft. The armature remains in contact with the rails during acceleration so as to impart a turning motion. The transfer shaft is physically coupled with and projects forwardly from the armature and transfers to the projectile the acceleration and the turning motion of the armature in the forward direction.
