摘要：An electric machine, in particular a rotary current generator, has a stator (10)secured in a housing and a claw polar-rotor system mounted on a shaft (2). The rotorsystem has a first polar ring (4) that ends in claws (41) and is designed as the half of apolar wheel, and a second polar ring (3) that ends in claws (31) and is mechanically linkedto the first polar ring (4) by non-magnetic linking means, forming the other half of thepolar wheel. The points of the claws (31, 41) of one polar ring (3, 4) extend into the gapsbetween the claws (41, 31) of the other polar ring (4, 3). An exciting winding (25) isassociated with the polar rings (3, 4) on the shaft side. In order to ensure a high stressresistant, easily accessible weld connection of the polar rings (3, 4), the non-magneticlinking means are constituted by a non-magnetic plate (5) that is adjacent to the surface(42) of the first polar ring (4) opposite to the claws (41) of the first polar ring (4) and thatis linked to said surface and to the points of the claws (31) of the second polar ring (3).
