LOHER低壓 J系列電機

J series Low-voltage motors for tailored drive solutions Overview General description Technical data overview Features Customer benefits Typical applications General description J series from Loher have a modular cooling design featuring double-flow inner cooling for a high power density and a homogeneous temperature distribution.2 versions are available: Mounted air-water heat exchanger (JNWA–... type for roller bearings / JNXA-... for sleeve bearings): Optimum cooling is guaranteed specifically for these series due to the harmonized and coordinated heat exchanger. The motor power loss is dissipated through the cooling water and is therefore de-coupled from the ambient temperature. The heat exchangers are available in a wide variety of versions with single and double pipe types. The high quality heat exchanger materials used are adapted to the specific requirements. Mounted air-air heat exchanger (type JNRA–... for roller bearings / JNQA-... for sleeve bearings): The motors are equipped with air-air heat exchangers. The cooling pipes are manufactured out of galvanized steel; stainless steel versions are available for especially aggressive atmospheres.
