Abstract
The series loop blocks of an armature end-winding structure are formed with grooves along a portion of their side surfaces to allow air flow to pass through the grooves to the series loop caps. Provision of the grooves on the side surfaces also facilitates machining of the ungrooved side surface portions of the series loop blocks for better fit and assembly between adjacent series loop caps.
