Electric motor rotor

The rotor (1) has a support structure (5) provided with a housing (10). A permanent magnet (15) is placed in the housing that comprises an external wall (35). The external wall comprises a holding strip (48) radially projected toward interior of the housing from the external wall to exert a support on the magnet for blocking the magnet in the housing along radial direction. Space is formed between the external wall and/or interior wall (30) of the housing and the magnet along the radial direction. The housing is extended through the support structure along the radial direction. An independent claim is also included for a method for manufacturing a rotor of an electrical motor. Ce Rotor comprend une structure de support (5) munie d'au moins un logement (10) dans lequel est logé un aimant permanent (15). Le logement (10) comprend une paroi extérieure (35), laquelle comprend au moins une languette de retenue (48) en saillie radialement vers l'intérieur du logement (10) à partir de la paroi extérieure (35) du logement (10), de sorte à exercer un appui sur l'aimant (15) de manière à bloquer l'aimant (15) dans le logement (10) selon la direction radiale.
