摘要

Rectifier performance with the low-inductance counter electromotive force (emf) load of a large d-c motor may be some-what different than the more conventional performance resulting from a highly inductive load. If, at low average values, the current is not continuous but flows in pulses, both the static and the dynamic characteristics of the rectifier-motor system are affected. In the case of a main drive motor for a hot strip mill stand, mill performance may be impaired by the dynamic characteristics associated with discontinuous current flow. One means of over-coming this is the addition of a series-saturating reactor to the armature circuit.
