The problem of motor control in industrial practise and especially in steel plant operation is one in which there is as great a diversity of opinion as in any other problem that presents itself to the industrial engineer. In this paper, it is the intention to take up some of the reasons for the use of automatic control for motors as opposed to manual control, and also some of the tests which have recently been made at the Youngstown Sheet & Tube Co. on the new developments in automatic control which have been brought about by the use of the series-wound accelerating switch, and the deductions and standards that have resulted from these tests, in connection with previous experience in automatic and manual control.
