Rotor having injected cage

The invention relates to a rotor (1) for a rotary electric machine, having a stack of magnetic laminations (2) that each have perforations (3), the superposition of these perforations (3) within the stack (2) forming notches (4), at least some of the perforations (3) having, on at least part of their periphery, friction reliefs, electrically conductive bars (10) of a first material, which are received in at least some of the notches (4) and bear against the reliefs by at least one main face (11). 本发明涉及一种用于旋转电机的转子(1)，所述转子具有：磁性叠片形成的叠片堆(2)，每个磁性叠片具有开口(3)，这些开口(3)在所述叠片堆(2)内的叠置形成狭槽(4)，所述开口(3)中的至少一些开口具有在其外围的至少部分上的摩擦凸起；导电杆(10)，所述导电杆由第一材料制成，所述导电杆容纳在所述狭槽(4)中的至少一些狭槽中，并通过至少一个主面(11)抵靠所述凸起。
