Abstract
A method for manufacturing a rotor of a rotary electric machine, including a stack of magnetic laminations defining the slots in which bars made from a first electrically conducting material are received, in which method a second electrically conducting material, different from the first, is injected using an injection machine, from the front of the laminations stack, the bars being held at their rear end against the pressure associated with the injection by a positioning tool that passes through a cavity used for forming a short-circuiting ring at the rear of the laminations stack.
