Series three-phase asynchronous electric motors LSFA It was developed by Leroy Somer especially for furnaces (baking, glass quenching, ceramic firing, etc.), they are able to withstand ultra-high temperature conditions, the upper limit for the shaft leaves 750 ° C, for the body up to 85 °C.
The design of the motors has a ribbed surface, the frame is made of aluminum, located on removable or cast legs, as well as a variation without them, the flanges and flange adapters are cast iron. The shaft is made of steel or refractory stainless steel, elongated design, keyway connection and central threaded hole.
They can be operated by digital frequency converters, additionally equipped with various sensors to provide thermal protection, valves for draining condensate and other options.
