www.weg.net Features and benefits New frame With the optimization of the frame’s structural design, the intent was the best equation between mechanical rigidity and thermal dissipation possible for enclosures, thereby reducing motor vibration and increasing lifetime. The HGF motor frames consist of a single piece of high strength cast iron. External and internal fins, in conjunction with the fan and fan cover, provide the maximum heat dissipation possible for a self-ventilated motor, thus enabling increased levels of rated power per frame size and avoiding the overheating of the motor. The...

www.weg.net Sleeve bearings Motors may be fitted with sleeve bearings as an optional feature in direct coupling applications. Sleeve bearings require less maintenance due to the fact that the lubrication intervals are up to three times longer than the lubrication intervals of conventional bearings, and specially because they present a lifetime similar or longer than that the motor itself. The sleeve bearings are also outstanding for their very low operating noise level and for supporting higher speed levels when compared to conventional bearings. New fan cover The new fan cover was designed...

www.weg.net IEC Non-Sparking (Ex nA) HGF Line NEMA Class I Division 2 HGF Line This line was developed for hazardous areas where explosive atmospheres may occur (as standard: an explosive atmosphere will probably not be present under normal operating conditions and, if any, this will be for short periods of time, that is, an explosive atmosphere may be present accidentally). This type of protection is applied to electrical equipment which does not cause ignition of an explosive atmosphere under normal operating conditions. The IEC Ex nA HGF motors have been certified by BASEEFA, according...
