| 摘要 |
<p>The invention relates to a commutator for an electric machine, which comprises a support element (1) produced from an insulating molded plastic material, a plurality of metallic conductor segments (3), arranged evenly about the commutator axis (2) and having connecting elements for a rotor winding. An interference suppressor (9, 9') is connected to the conductor segments (3) in an electrically conductive manner and comprises a number of individual interference suppressing elements (10) corresponding to the number of conductor elements (3). The conductor segments (3) are provided with contact studs (18) that are connected at a distance from their base (19) in associated points of contact (23) with the adjacent contact poles (24) of two adjacent interference suppressing elements (10). The contact studs (18) are designed to be radially resilient and are separated from the adjacent rigid components of the commutators in the area between the base (19) and the point of contact (23) such that the position of the contact studs (18) relative to the adjacent rigid components of the commutator can be modified due to thermal expansion in said area.</p> |
