Abstract
A permanent-excited electric motor/induction machine has a laminated core (1) made of stator laminations (11) and a yoke winding (2). The yoke winding (2) has an inner winding part (21) and an outer winding port 22. The inner winding part 21 is arranged radially inside the stator lamination (11) in at least one winding receptacle (3). The outer winding part (22) is arranged radially outside the stator lamination (11) on an outer surface (4) of the laminated core (1). A soft-magnetic shield (5) is formed on the entire circumference around the outer winding part (22). At least one nonmagnetic connecting element (6), that contacts the stator lamination (11) and the soft-magnetic shield ring (5), is arranged between the stator lamination (11) and the soft-magnetic shield (5).
