Multiturn coil for field poles of dynamoelectric machine

A multiturn coil assembly comprising:

• outer, intermediate and inner electrically interconnected windings, having conduit means for passing of a cooling fluid therethrough,
• each winding occupying a single vertical row of turns over the entire coil height, being wound with an equal number of turns stacked in the same direction as the other windings, and having first and second terminals;
• said windings being concentrically arranged so that the inner peripheral dimension of said outer winding is substantially equal to the outer peripheral dimension of said intermediate winding, and the inner peripheral dimension of said intermediate winding is substantially equal to the outer peripheral dimension of said inner winding;
• each winding being oriented so that said first terminals of all the windings are positioned adjacent one another and adjacent one end surface of said coil assembly, while said second terminals of all the windings are positioned adjacent one another and adjacent the other end surface of said coil assembly;
• all the terminals of all the windings being directed towards only one side of the coil assembly and electrically interconnected adjacent the outer surface of said one side of the coil by means of non-intersecting connectors;
• said connectors also serving as conduits for passing a cooling fluid therethrough.
