An electric machine

Abstract

An electric machine comprises a stator (101) and a rotor (102) rotatably supported with respect to the stator. At least one of the rotor and the stator comprises a core structure (103) and windings whose coil sides (104) are located in slots of the core structure. Openings of the slots are provided with tapes (105) each having a body section (106) comprising at least one surface coated with adhesive material (115) attaching the tape in place in one of the slot openings. Each tape further comprises one or more electric conductor strings (107-109) in mechanical contact with the body section. The electric machine comprises electric conductors (110) having galvanic connections with a stator frame and with the electric conductor strings of the tapes. Thus, the electric conductor strings of the tapes constitute a capacitive shield that reduces capacitive coupling between the stator and the rotor and thereby reduces bearing currents.
