GENERAL PURPOSE 3-PHASE INDUCTION MOTORS Efficiency of motors in the USA USA began to regulate efficiency of electric motors in 1992 with the “Energy Efficiency Provision” of the Energy Policy Act (EPAct). In 1997, USA was the first country in the world to establish minimum energy performance standards (MEPS) for electric motors manufactured in or sold to USA. Generalpurpose motors 1HP-200HP were required to meet NEMA Energy Efficient standard (EPACT). In June 2016, efficiency standards in the USA were increased once again with the Integral Horsepower Motor Rule (IHMR) which superseded the...

GENERAL PURPOSE 3-PHASE INDUCTION MOTORS Insulation classification The insulation system of an electric motor is determined by a given insulation class on the basis of its thermal resistance. This thermal resistance should be guaranteed by the entire set of electric insulating materials used in the motor insulating system. Thermal resistance classification is related to the temperature of the hotspot in the insulation occurring during rated operating conditions of the electric motor, allowing for the highest permissible rise in average temperature. This rise should be selected so that at...

Hazardous Locations Classification Our NEMA PREMIUM motors can be delivered in special execution for Hazardous Locations and are certified for Groups A, B, C, D, F and G. CLASS – Defines the type of hazardous material (explosive or ignitable substances). Class I flammable gases, vapors or liquids, such as acetylene, hydrogen, ethylene, gasoline, etc. combustible dust such as: coke dust, grain dust, etc. easily ignitable fibers or flyings, such as: textile, saw dust, etc. DIVISION – Defines the likelihood of the hazardous material being present in an explosive or ignitable concentration....

Cooling General purpose motors from Cantoni Group are equipped with standard IC411 cooling. Other cooling methods (for example motors with external/separate cooling) are available on request. IC code – Fan mounted on shaft – Often called “drip-proof” motor – Surface cooled by natural convection and radiation – Without internal or external fan – Smooth or finned casing – External shaft-mounted fan – Often called TEFC motor – Smooth or finned casing – External motorized axial fan integrated with the motor – Smooth or finned casing – External motorized radial fan integrated with the motor –...

GENERAL PURPOSE 3-PHASE INDUCTION MOTORS Standard terminal box equipment Motor frame size Number of supply leads Number of threaded inlet holes Size of threaded inlet holes [inch] Optional rotation of terminal box Temperature sensors in the winding Thermal protection of bearings Vibration level The rotors balancing method guarantees that standard vibration level of motors is much lower than required for general industrial motors according to NEMA MG-1 (0.15in/s). On customer’s demand the motors can be produced with even more reduced vibration level. Vibration level in standard and reduced...

Terminal box The standard mounting position for NEMA motors is F1 – the terminal box is located on the left side of the motor facing the output shaft and it is equipped with 9 (size 143T...184T) or 12 (size 213T...447T) supply leads (without terminal block). Our NEMA PREMIUM motors are also available with terminal box on right side (F2) or on top (F3). As standard, motors are offered with aluminium terminal box for sizes 143–286, and cast iron for sizes 320–440. As optional execution, for sizes 143–286 can be also cast iron terminal box.
