Abstract

The method of securing the output ends of rectangular cross-section stator conductors is capable of withstanding the high electromagnetic forces acting on the windings as they leave their slots in the stator casing and avoids the consequent damage to insulation. Expanding filling pieces or shims are inserted between stator conductors so that they form a continuous-circular arch. Expansion of the wedge shaped shims in a tangential sense provides a compressive holding force on the arch. The wedging arrangement is held in place by a form of lacing (56) providing a radial force on the shims. Each shim has a movable quoin which produces the tangential force when forced radially.
