A rotor assembly for an electromechanical device includes a molded wire support. In a conductive printed board having terminals which are provided either in a contiguous manner or at a defined array spacing, and are connected to conduction paths, terminals connected to the terminals and spaced with different array spacing from the defined array spacing are provided on the ends. Such aerogel materials and methods of manufacturing the same are described. Compression for the tile related to the primitive is disallowed in the characteristic indicates the final compression will not be retained.
