摘要： A method of manufacturing an electric machine that includes providing a core defining a slot, coating a magnet body prior to installation of the magnet body into the slot and installing the magnet body into the slot wherein the coating on the magnet body has a thermal conductivity of at least about 0.3 W·m−1·K−1, advantageously of at least about 0.5 W·m−1·K−1, and even more advantageously of at least about 2 or 3 W·m−1·K−1 and wherein the coating is in a partially cured condition when the magnet body is inserted into the slot. The coating may form a substantially voidless material bridge between the magnet body and the core over at least a portion of the magnet body and thereby thermally couple the magnet body with the core. An electric machine manufactured in accordance with the method is also disclosed.
