Emissions from an Overheated Electric Motor with Slot Cells and Winding Phases Insulated with an Aromatic Polyamide Paper
Abstract
A standard Navy 10-horsepower electric motor, with varnish wire and slot cells and phases insulated with an aromatic polyamide paper, was operated in a glass enclosure at sequential operating temperatures (from 73C to 334C) in order to trap possible hydrogen cyanide and/or other volatile emissions generated under normal and overheat conditions. The total emission of hydrogen cyanide (669 micrograms) on heating would produce only 0.02 parts per million hydrogen cyanide concentration if this amount were released in a 1000 cubic-foot room. Only aldehydes reached the threshold limit value (2 parts per million).
