The National Electrical Manufacturers Association NEMA suggests that a motors voltage range is plus or minus 10 of the nameplate voltage. Therefore, a motors nameplate that states 115 volts, can be supplied a voltage between 104 V and 126 V. A 230 V motor can be supplied with a voltage between 207 V and 253 V.
As regards abnormal rolling conditions - which are more or less very normal for rolling mills - roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll failure have to be discussed and determined or vice versa to reduce the risk of repeated roll
