NM112 technical data<\/h2>\n<\/div>\n

NM112 opens the mid-range group with 70 N.m nominal torque and a 48 mm maximum bore. It is often evaluated when a drive has a noticeably larger shaft interface but still operates within a 3000 rpm limit.<\/p>\n<\/div>\n

Pumps, mixers, conveyors and general machinery can bring different starting behavior to the same nominal power. For NM112, state whether the drive starts loaded, cycles frequently or sees process shock so the application can be reviewed beyond its 70 N.m continuous rating.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
