Abstract: There is described a method and apparatus for forming a core for an electrical machine, in which a stamped metal strip (4a, 4b) is wound onto a mandrel (22), to form a helical winding. The diameter of the mandrel is then increased to apply tension to the wound strip, while the coils of the wound strip are held between clamps (24, 25). The coils of the wound strip are then fixed relative one to another (50, 51), while the coil is held at the increased diameter. The diameter of the mandrel is then reduced to disengage the laminated core from the mandrel. To produce a rotor or stator for an electrical machine, electrical coils are mounted in slots formed in the inner or outer surface of the core. The rotor or stator may then be incorporated into an electrical machine such as a motor or generator.
