Abstract :
TRANSIENT, as well as the steady-state characteristics, of d-c motors and generators must be known if the rolling-mill system performance is to be thoroughly analyzed and the operating performance predicted. This digest presents the transient characteristics of the d-c machine. The constants are divided into three phases of d-c machine performance: (1) direct- or main-axis field, (2) the quadrature axis or interpolar axis, and (3) the mechanical or speed axis.
