1. A rotor comprising:
a rotor winding including a top surface, wherein said rotor winding includes a core recess defined through a thickness of the rotor winding;
a core shaped to be inserted into said core recess;
a raised protrusion positioned on and extending from the top surface of said rotor winding adjacent said core recess when said core is partially inserted into said core recess, and said raised protrusion adapted to be pushed into said core recess;
and
said raised protrusion configured to deform upon application of force to the top surface of said rotor winding when said core is pushed into said core recess so that material from said raised protrusion flows from said top surface into said core recess to secure said core within said core recess.
