用于旋转电机的转子，包括限定磁屏障的至少两个极性构件的开放链

Rotor for rotary electric machine including open chain of at least two interpolar members defining magnetic barrier
Abstract:
A rotor (24) for a rotary electric machine (20), mainly for the automotive industry, has a front polar wheel (46N) and a rear polar wheel (46S). Each polar wheel (46N, 46S) includes claws (52) extending axially towards the other polar wheel (46N, 46S). Each claw (52) of the polar wheel (46N, 46S) is circumferentially interleaved between two claws (52) of the other polar wheel (46N, 46S). At least two interpolar gaps (62) are provided between the side faces (60) opposite two consecutive claws (52), and at least two members (68) defining a magnetic barrier are provided in two interpolar gaps (62) associated on either side of a predetermined claw (52D). The front longitudinal ends (72) of the two members (68) are connected by a connector (82) in order to define an open chain (80).
Abstract(Chinese):

主要用于汽车工业的用于旋转电机（20）的转子（24）具有前极轮（46N）和后极轮（46S）。 每个极轮（46N，46S）包括轴向延伸朝向另一个极轮（46N，46S）的爪（52）。 极轮（46N，46S）的每个爪（52）在另一个极轮（46N，46S）的两个爪（52）之间沿周向交错。 在与两个连续的爪（52）相对的侧面（60）之间提供至少两个间极间隙（62），并且限定了磁屏障的至少两个构件（68）设置在两侧相关的两个间隙（62） 的预定爪（52D）。 两个构件（68）的前纵向端（72）通过连接器（82）连接，以限定开链（80）。
