Abstract
A magneto repulsion electrical tape wound coil has been developed with improved current distribution and improved heat transfer. The coil is easy and is expensive to manufacture and simple to mount. The coil comprises a conductive strip (e.g., a copper strip) with rectangular openings stamped in it with a standard metal stamp. The single row of openings are at regular intervals and arranged so that the width of the openings and the spacing of the openings is such that when the coil is wound there is an overlap of the openings, forming radial passages extending from the outer periphery of the coil to its central core electrode. Cooling fluid may be supplied from a hollow inner electrode so that the cooling fluid flows radially, outwardly. Since the openings overlap to form radial passages, a cross-flow path for the cooling fluid may be established where fluid enters the passages on one side of the coil and exits from the other side of the coil.
