Abstract

The present invention relates to a rotor of a rotary electric machine with flux concentration, comprising: - a shaft (2) extending along an axis of rotation of the rotor, and - a rotor mass (3) fitted onto the shaft, having a central opening for fitting it onto the shaft, and comprising: - permanent magnets (7) fitted into housings opening radially onto the central opening (5), - a stack of magnetic laminations (4), at least one of the magnetic laminations being of a single piece, the stack defining the housings (18) in which the permanent magnets are fitted.
