Abstract: A coil for an electric machine including a conductive strand having a first end, a second end, and a plurality of windings between the first and second ends and an electric insulating body within which the conductive strand is at least partially encased, wherein at least a portion of the insulating body includes perforations that allow a coolant to penetrate into the insulating body to cool the coil during use of the electric machine. A method of making the coil includes molding or printing the insulating body about the conductive strand so as to have perforations therein.
