The invention relates to a DC motor, particularly for a fan device of a motor vehicle, having a stator and a metal grounding plate arranged on the stator, for receiving at least one leadthrough capacitor of an interference suppressor device. The capacitor being arranged in a connection line of the motor. According to the invention, the leadthrough capacitor includes a metal housing with at least one contact section for contacting the stator and/or the metal grounding plate. Thus, a compact interference suppressor device, which can be produced in a cost-effective way and is easy to install, is achieved.

DC motor with a leadthrough capacitor

A DC motor (), in particular for a blower device of a motor vehicle, having a pole housing (), a plurality of contact elements () effecting the bonding to a collector (), a pole housing opening () making it possible to feed electrical connection lines () through into the pole housing (), and an interference suppressor () serving to reduce and/or eliminate line-conducted electrical interference signals, in which the interference suppressor () has at least one leadthrough capacitor (), which is located in an electrical path of at least one connection line (). The invention further relates to an electrical interference suppressor () for an electrical device located in a housing, in particular for a DC motor () in a pole housing (), as well as to the use of a leadthrough capacitor () for interference suppression in a DC motor ().
