Discussion on “concatenated induction motors for rolling mill drive” (Oschmann), Detroit, Mich., June 23, 1914. (see proceedings for June, 1914)

Rudolph Tschentscher: The three points which stand out very prominently to me as a steel man are these: First, the exceptional reliability of the equipment — it entailed a loss of a little over one hour´s time in practically a year´s operation; second, the low operating cost, there being no additional attendance required; and third, probably greater than either of the other two, the rapidity of the control movement. I think the paper gives the time for braking, reversing the forward motion, as being done within one minute. That, to one in the steel business, means a very considerable saving in tonnage.
