Title (EN) ELECTRIC MACHINE APPARATUS
(FR) APPAREIL DE MACHINE ÉLECTRIQUE
Abstract:
(EN) The present disclosure relates to a rotor (3) for an electric machine (1). The rotor (3) includes a plurality of permanent magnets (6-n), each permanent magnet being mounted in a magnet aperture (10-n) formed in the rotor (3). A plurality of flux barriers (11-1, 11-2, 12-1, 12-2, 23-1, 23-2) and bridges (13-1, 13-2, 14-1, 14-2, 24-1) are formed in the rotor (3). The bridges (13-1, 13-2, 14-1, 14-2, 24-1) are each formed between one of said magnet apertures (10-n) and an adjacent one of said flux barriers (11-1, 11-2, 12-1, 12-2, 23-1, 23- 2). Each bridge comprises opposing first and second sides (15-1, 15-2, 16-1) formed by the magnet aperture (10-n) and the flux barrier respectively. The first side includes a first circular arc (17B, 21B, 27B, 33B, 37B) (17B, 21B, 27B) and the second side includes a second circular arc (18B, 22B, 28B, 34B, 38B) (18B, 22B, 28B). The present disclosure also relates to an electric machine (1) including a rotor (3); and to a vehicle (2) including an electric machine (1).
(FR) La présente invention se rapporte à un rotor (3) pour une machine électrique (1). Le rotor (3) comprend une pluralité d'aimants permanents (6-n), chaque aimant permanent étant monté dans une ouverture d'aimant (10-n) formée dans le rotor (3). Une pluralité de barrières de flux (11-1, 11-2, 12-1, 12-2, 23-1, 23-2) et des ponts (13-1, 13-2, 14-1, 14-2, 24-1) sont formés dans le rotor (3). Les ponts (13-1, 13-2, 14-1, 14-2, 24-1) sont formés chacun entre l'une desdites ouvertures d'aimant (10-n) et une barrière adjacente parmi lesdites barrières de flux (11-1, 11-2, 12-1, 12-2, 23-1, 23- 2). Chaque pont comprend des premier et second côtés (15-1, 15-2, 16-1) opposés formés par l'ouverture d'aimant (10-n) et la barrière de flux respectivement. Le premier côté comprend un premier arc de cercle (17B, 21B, 27B, 33B, 37B) (17B, 21B, 27B) et le second côté comprend un second arc de cercle (18B, 22B, 28B, 34B, 38B) (18B, 22B, 28B). La présente invention concerne également une machine électrique (1) comprenant un rotor (3) ; et un véhicule (2) comprenant une machine électrique (1).
