Abstract
A method for manufacturing an inner rotor for a rotary electric machine, the rotor comprising a plurality of pole pieces surrounding a shaft, each pole piece being made from a stack of metal sheets () made of magnetic material, the pole pieces delimiting recesses between them for permanent magnets. The method comprises, in succession the steps of cutting blanks () each grouping together n metal sheets (), 'n' being the number of poles of the rotor, the n metal sheets of a blank being held together by temporary bridges () straddling the recesses, at least two bridges each comprising an outer lug (), stacking the blanks while keeping them aligned via the outer lugs, immobilizing the stack of blanks, and eliminating all the temporary bridges in order to free up the radial access to the recesses.
