A motor encoder is a rotary encoder mounted to an electric motor that provides closed loop feedback signals by tracking the speed and/or position of a motor shaft. There are a wide variety of motor encoder configurations available such as incremental or absolute, optical or magnetic, shafted or hub/hollow shaft, among others.

Looper and tension control, shown in Fig. 2, is important in hot strip mills because they affect both the dimensional quality and the mass flow of a strip. The high strip tension between stands induces width shrinkage, thickness reduction and moreover can produce an edge wave on a strip. However, it does make the mass flow more stable and hence ...
