IEC standard or SEW drive end solution
The standard IEC flange configurations are commonly required for the majority of pump, fan and gearbox applications. However, as SEW Eurodrive are a major supplier to the food industry, Marlin Stainless offer the option of the special shaft and flange dimensions required by this range of gearboxes to enable direct replacements.
TEFC and TENV
Totally Enclosed Fan Cooled (TEFC) motors rely on air being pulled from the back end of the motor through a fan, this is then blown over the motor body to dissipate the generated heat. Whereas, Totally Enclosed Non Ventilated (TENV) motors work on the basis of more active material and better efficiencies reducing the heat generated through losses. This negates the need for a fan at all. The TENV type motors are, as a result of this, slightly shorter and again have cleaner lines and fewer areas for entrapment of dirt.
