Abstract
A method for forming the heads of coils made of rectangular wire so that it fits within the slots of the stator of an electric machine. The method includes receiving a coil having unformed first and second heads separated by first and second legs and applying controlled deformation to yield properly shaped heads. Actuators are provided for causing sequential actuated movements of one of the first and second legs to force the head-forming elements into contact with different portions of the first and second heads while allowing selective free movements of the other leg in response to the actuated movements.
