NM82 technical data<\/h2>\n<\/div>\n

NM82 sits between the compact NM67 and the larger-bore NM97. Its 32 mm maximum bore makes it relevant to many small and medium rotating-equipment interfaces where shaft fit becomes the first sizing filter.<\/p>\n<\/div>\n

The nominal rating is 28 N.m with a 3000 rpm speed limit. NM82 can be evaluated for pump sets, blowers and machinery with moderate continuous duty, but loaded starts and repeated cycling should be stated rather than hidden inside a generic motor-power figure.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
