This standard specifies the technical requirements, test methods, inspection rules, quality guarantee period, marking, packaging, transportation and storage requirements for ZCF series DC tachometer generators. This standard applies to ZCF series DC tachometer generators. This series of motors is a closed self-cooling separately excited DC generator with a commutator. Under constant excitation current, the armature voltage generated is proportional to the armature speed.
