Abstract
Lap wound direct-current dynamoelectric machines may allow excessive currents to flow in single turn windings when such machines are operated at relatively low speeds and/or relatively high voltages, and plural turn windings cannot be practically formed from heavy gauge wire, or from heavy gauge rectangular wire or from rectangular wire, to efficiently fill armature slots. A plural turn, preformed winding is disclosed having two ends for connection to commutator segments substantially adjacent each other on the armature, and with at least four sides defining at least two open turns, for engaging slots in the armature core which are spaced substantially 90.degree. apart for a four pole machine. A three open turn winding is also disclosed. The number of open turns is limited only by space available in the armature coil slots.
