The ingots produced were rolled to blooms and then slabs in the Templeborough Cogging Mill.

The unique advantage of ironless DC motors is that there is no cogging (torque variations caused by changing attraction between the iron and the magnets).

Because there is no magnetic iron core, ironless in runners have no "cogging", in that they spin freely with no magnetic interaction when power is disconnected.

I will be hang'd, if some eternal villain, Some busy and insinuating rogue, Some cogging, cozening slave, to get some office, Have not devised this slander; I'll be hang'd else.
