General Purpose 3-phase Induction Motors INTRODUCTION New efficiency classes for the low-voltage three-phase motors (IE = International Efficiency). Along with the international discussion on energy efficiency a worldwide harmonized energy efficiency classification system has been established for low-voltage three-phase asynchronous motors. For many years low-voltage three-phase motors in the European Union have been sold in three efficiency classes EFF3, EFF2 and EFF1. Aside from this, many different efficiency classification systems have been introduced and well-proven in many countries...

General Purpose 3-phase Induction Motors EFFICIENCY OF MOTORS Cantoni Motor has in offer general purpose standard efficiency motors of (2) Sg, Sh series which fulfil IE1 class requirements according to the IEC 60034-30 standard. The present catalogue describes the electric motors which belong to the efficiency class IE2 (High Efficiency) and motors excluded from the IEC 60034-30 standard (motors with 2p = 8, 10, 12 and with rated output below 0.75kW and above 375kW). Comparison between the efficiency of Cantoni Group motors (for example 2p=4) and efficiency class IE1/IE2 requirements...

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...

General Purpose 3-phase Induction Motors INTERNATIONAL PROTECTION IP According to the IEC 60034-5 standard the electric motors are provided with IP code which determines the degree of protection (ensured by the housing) against penetration of solid matter and fluids. PROTECTION AGAINST PENETRATION OF FLUIDS PROTECTION AGAINST PENETRATION OF SOLID MATTER 1st digit MECHANICAL PROTECTION Protected against vertically falling drops of water Protected against solid bodies larger than 50 mm Protected against solid bodies larger than 12 mm Protected against solid bodies larger than 2.5 mm Protected...
