Motor Cooling

The document discusses various electric motor cooling systems from Van Houcke UK Ltd. It describes different types of cooling for low voltage motors including totally enclosed naturally ventilated (TENV), totally enclosed fan cooled (TEFC), and totally enclosed force ventilated (TEFV) motors. It also discusses open drip proof (ODP) motors that are self-ventilated, force ventilated, or ventilated from an independent air source. Medium and high voltage motors can be ribbed, smooth cast iron, or steel fabricated and cooled via TEFC, TEFV, or different air or water cooling systems.
