Electric motor with interference suppressor

摘要

An electric motor includes a commutator housing mounted integrally with a stator. The housing includes brushes and an interference suppressor filter that links the brushes pairwise. A commutator including a support ring is integrally mounted with a rotor shaft and has a plurality of metal segments arranged around a circumference of the support ring. A capacitor is connected between two adjacent metal commutator segments. Combining the two interference suppressor devices directly on the commutator and the commutator housing maximally reduces spurious signal emissions and satisifies the most stringent electromagnetic noise class requirements.
