ABSTRACT:
The motor housing comprises a cup-shaped ferromagnetic part having an open end and an axial end plate of ferromagnetic material closing off the open end to form a motor housing of rectangular cross-section when viewed in longitudinal section. A generally disk-shaped rpm-signal generating structure is mounted interiorly of the motor housing, coaxial with the rotor axis, at one axial end of the housing, and just inward of a wall of the motor housing which forms part of the flux-conducting magnet system of the motor, whereby such wall shields the rpm-signal generating structure at least against electromagnetic interference originating exteriorly of the motor housing. The motor comprises slip rings or commutator segments on whose surfaces stationary brushes ride. The brushes are provided with longitudinal recesses, projections or internal bores, so that the brush configuration itself makes for longitudinal brush guidance, and the brushes are mounted on brush guide members which engage such longitudinal portions of the brush. The rotor shaft and the motor housing are conductively connected by means of a contact element engaging the rotor shaft at one axial end, to prevent build-up of electrostatic fields as between the rotor shaft and the motor housing.
