Abstract
A three phase winding for a high voltage machine with Y connected legs, whose coil groups, disposed on the circumference so as to be cyclically distributed, consist of series connected coils alternatingly energized in the opposite sense, has its size and copper requirements reduced by providing as many coil groups with the same direction of the magnetic flux and direction of increase in potential as there are coil groups of opposite direction of the magnetic flux and direction of increase in potential with the groups so distributed over the circumference and interconnected lengthwise that, at most, the phase voltage is applied to the phase transitions between adjacent coil sides.
