motor enclosures

[rluxton]

For years I have heard motor enclosure definitions in terms of "open/drip proof", "TEFC ... totally enclosed fan cooled" but have not seen a formal definition of especially the first one, ODP. Does anyone know of a definition source? And, does any one know of a source that compares the American ODP, TEFC, etc to the International Protection rating system for enclosures for motors and other devices?
