The Study of Continuous Rolling Mill Inter The study aims to determine effect of the fluctuating technological conditions of rolling on distribution of inter- stand tensions and loads of rolling motors for three variants of the continuous rolling mill: with the speed control system only, for electric drive of the rolling mill with properties of the torque ,...
Universal motor The universal motor is modified in several ways to allow for proper AC supply operation There is a compensating winding typically added, along with laminated pole pieces, as opposed to the solid pole pieces found in DC motors A universal motor's armature typically has far more coils and plates than a DC motor, and hence fewer windings per coil...
Characteristics of DC motors Generally, three characteristic curves are considered important for DC motors which are, (i) Torque vs armature current, (ii) Speed vs armature current and (iii) Speed vs torque These are explained below for each type of DC motorThese characteristics are determined by ,...
Rolling Mill Let us revisit the rolling mill introduced in Chapters 1 and 3 It was decided to use drawing force and roll gap as control inputs and keep the rolling speed constant; the input thickness cannot be manipulated and will be used for feedforward control...
