  • Commutator motor with a retention device for retaining a brush during assembly
    Patent number: 6333580
    Abstract: An axially movable protective sleeve is provided for the axial assembly of a rotor-side commutator onto a stator-side brush holder. The protective sleeve both protects against moisture and provides an axial assembly that is simple in production. The axially movable protective sleeve encircles a commutator, and initially secures brushes in a retention position for assembly and then releases the brushes to rest on a brush contact surface of the commutator, when the commutator is in its operational end position.
