Title:
COMMUTATOR FOR AN ELECTRICAL MACHINE AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO2004038905
Kind Code:
A3
Abstract:
The invention relates to a commutator for an electrical machine, comprising a carrier body (1) produced from a moulding material, and a plurality of metallic conductor segments (3) which are homogeneously arranged on said carrier body about the commutator axis (2) and comprise connecting elements arranged thereon. Said carrier body (1) has two regions which are produced from different moulding materials and are pressed against each other in a positively locking manner, namely a carrier body base (11) and a leakage current screen (9). The radially outwardly open leakage current screen (9) comprising isolating surfaces (10) charged with a leakage current is arranged between the conductor segments (3) and consists of a first moulding material which is more resistant to leakage current than the second moulding material of the carrier body base (11) .
