Abstract: In a field winding for a rotor (12) in an electrical power generator, a slip plane (36) between the top winding (28) of the rotor and the stack of windings below the top winding to reduce the thermal strain energy in the rotor. The slip plane allows the winding stack to slide underneath the top winding to relieve thermal stress in the stack. Because the top winding is isolated by the slip plane, thermal stresses created in the top winding are confined to the top winding. Similarly, the corners (44) of the end turns (18) for the top winding are wider than the end turn corners of the underlying winding stack. These wide top end turns abut the corner end blocks (46) for the field winding. The winding stack underneath the top turn is free to expand from thermal excitation, because the end turns of the stack are not confined by corner end blocks. <IMAGE>
