CDA - No run of the mill starter

This was the case when their 2-high rolling mill became increasingly unreliable. The enormous torque required by the mill is supplied by a 16 ton flywheel driven originally by the waterwheel but since 1957 driven by a 142hp slip-ring motor.

Slip ring - Wikipedia

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.
