GleichstromDynamos
GleichstromDynamos are electrical machines that convert mechanical energy into direct current. They operate on the same basic principle as other dynamos: a rotating armature placed in a magnetic field induces voltages in the windings; a commutator and brushes rectify this alternating voltage so the external circuit sees a unidirectional current.
Construction and operation: The device comprises a rotating armature with coils, a stator that provides magnetic
Types: excitation can be separated (independent field supply), self-excited (shunt, series) or compound. Shunt and compound
Winding schemes include lap and wave windings, which affect the distribution of current in the armature and
Applications and history: GleichstromDynamos were central to early electric power systems and rail traction, as well
