Abstract: A winding frame structure for an automation winding machine to conveniently produce the windings of a motor includes two barrier plates, four ceramic heat conductive structures with high heat conductivity, and special-structured grooves. The ceramic heat conductive structures can significantly enlarge the heat dissipation area of the windings.
