STATOR FOR AN ELECTRICAL MACHINE WITH IMPROVED PROTECTION AGAINST POTENTIAL DIFFERENCES BETWEEN ADJACENT STATOR COILS

A stator (5) for an electrical machine (1) is described, which comprises an annular stator base body (7) with stator grooves (13, 13a, 13b) which are open towards the inside, and stator coils (14a, 14b) of a stator winding (8) which are arranged in the stator grooves (13, 13a, 13b) and assigned to a...

Summary:A stator (5) for an electrical machine (1) is described, which comprises an annular stator base body (7) with stator grooves (13, 13a, 13b) which are open towards the inside, and stator coils (14a, 14b) of a stator winding (8) which are arranged in the stator grooves (13, 13a, 13b) and assigned to a plurality of phases (L1 . . . L3) of the electrical machine (1). Adjacent stator coils (14a, 14b) of the same phase (L1 . . . L3) are here contra-wound and electrically connected in parallel. Furthermore, an electrical machine (1) with such a rotor (3a . . . 3c), and a drive arrangement and a vehicle (17) with such an electrical machine (1) are described.
