ABSTRACT:
An electromechanical machine having an improved arrangement for sealing lead wires. A housing structure of the electromechanical machine includes a tubular lead conduit, such as a short pipe section, through which the lead wires extend. A resinous sealing compound, such as an epoxy, is located within the tubular lead conduit. The lead wires are thus potted, and a predetermined degree of isolation is provided between the inside of the machine housing and the ambient environment. Preferably, the inner surface of the tubular lead conduit defines a labyrinthine structure, such as a series of parallel grooves, to further enhance the sealing function.
