A winding for a rotor in a pulse power AC generator has an electrical conductor extending along a closed loop path about an exterior periphery and first and second opposite ends of the rotor core. The conductor includes at least four side conductor portions having first and second opposite ends, and at least four end conductor portions interconnecting the side conductor portions to complete the closed loop path. The side conductor portions extend generally parallel to one another along generally linear portions of the closed loop path and are disposed along and angularly displaced generally ninety electrical degrees from one another about the rotor core exterior periphery. A first pair of the end conductor portions are disposed at the first opposite ends of the side conductor portions along the first end of the rotor core and interconnect respective adjacent pairs of the side conductor portions. A second pair of the end conductor portions are disposed at the second opposite ends of the side conductor portions along the second end of the rotor core and interconnect respective opposite pairs of the side conductor portions. The end conductor portions of the first pair thereof extend along respective non-crossing back-to-back generally ninety electrical degree portions of the closed loop path, whereas the end conductor portions of the second pair thereof extend along respective generally linear portions of the closed loop path which cross one another in a generally orthogonal relation.

An electromagnetic projectile launcher which uses a pulsed AC generator with a power supply. The generator is operative to supply a relatively low current pulse to initially accelerate the armature after which an extremely high current pulse is applied for main acceleration. The pre-acceleration pulse may be derived from an auxiliary winding on the generator or may be provided by a relatively smaller generator operated in synchronism with the main generator or physically coupled thereto.
