    • A rotation transmitter for rotor-excited electrical machines, in particular for synchronous generators in motor vehicles, is disclosed, which has a primary part (14) with a primary core (17) comprised of a magnetically conductive material and a primary winding (18) inserted into it, and has a coaxial secondary part (15) that can rotate in relation to the primary part (14) and has a secondary core (20) comprised of magnetically conductive material and a secondary winding (21). In order to achieve a small diameter design and in order to control the radial forces produced in the rotating secondary core (20), the primary and secondary parts (14, 15) are disposed next to each other in the axial direction and the primary and secondary cores (17, 20) have flat end faces (171, 201) oriented toward each other, which enclose an axial working air gap (23) between them
    • 公开了一种用于转子激励电机的旋转发射器,特别是用于机动车辆中的同步发电机,其具有主要部分(14),主要部分(14)具有由导电材料和初级绕组(18)组成的初级铁芯(17) 并具有能够相对于主要部分(14)旋转的同轴二次部件(15),并且具有由导磁材料和次级绕组(21)组成的次级芯体(20)。 为了实现小直径设计并且为了控制在旋转次级芯(20)中产生的径向力,主要和次要部件(14,15)在轴向方向上彼此相邻设置,并且主要和 二次铁心(17,20)具有朝向彼此定向的平坦端面(171,201),其在它们之间包围轴向工作气隙(23)
