Abstract
A field assembly for a motor includes a connecting terminal for making electrical contact with a point intermediate the ends of a field winding. A terminal board configuration provides pocket portions for engaging a turn of the winding, including the intermediate contact point, and for retaining the turn of the winding fixed relative to the assembly. The turn is brought out during a winding process and is engaged by one or more of the pocket portions. A frictional terminal is inserted into one of the pocket portions to provide frictional electrical connection to the intermediate point. The terminal boards are each configured to have a plurality of pocket portions. Pocket portions engaging and providing electrical contact with ends of the winding are arranged on terminal boards mounted on one end of the assembly. Pocket portions engaging and providing electrical contact with the intermediate point on the winding are arranged on a terminal board mounted on an opposite end of the assembly.
