Abstract
An axial flux motor may include a motor housing, a shaft rotatably mounted in the housing, and a stator mounted in the motor housing, and having a stator ring and a through-hole through which the shaft extends. Two rotors may be mounted on the shaft within the motor housing on opposing sides of the stator, each rotor having a plurality of magnets arranged radially on a stator-facing surface thereof. In addition, magnet wire may be wound on portions of the stator, the magnet wire comprising an inner coolant passage disposed within a copper tube, and a green glass coating on an outer surface of the copper tube, the green glass coating comprising glass solids, one or more of surfactants, solvents, and polymers.
