GENER AL PURPOSE 1-PHASE INDUCTION MOTORS Efficiency of motors New efficiency classes for the low-voltage three-phase and single-phase motors (IE = International Efficiency). Along with the international discussion on energy efficiency a worldwide harmonized energy efficiency standard classification system has been established for low-voltage three-phase and single-phase asynchronous motors. The standard IEC 60034-30-1 defines and harmonizes worldwide the efficiency classes IE1, IE2, IE3 and IE4 for low-voltage three-phase motors in the power range from 0,12 kW to 1000 kW (2p=2, 4, 6, 8)...

New EU Commission Regulation regarding minimum efficiency of electric motors pursuant Directive 2009/125/EC will repeal Regulation 640/2009 (including amendment 4/2014) on 2021-07-01. Motors covered by new Regulation Type general purpose, geared, with brake, Ex Rated power Motors excluded from new Regulation • multi-speed, slip-ring and with mechanical commutators • motors completely integrated into a product whose efficiency cannot be tested independently from the product • motors with an integrated variable speed drive (compact drives) whose efficiency cannot be tested independently from...

Definitions Relation between rated output power and rated torque on motor shaft: T= where: • T [Nm] is rated output torque on motor shaft • P [W] is rated output power on motor shaft • n [rpm] is rated speed of motor shaft Relation between rated output power on shaft and rated consumed power from mains: P1 = P × 100 η where: • P1 [kW] is rated consumed power from mains by motor • P [kW] is rated output power on motor shaft • η [%] is rated efficiency of motor Relation between rated consumed power from mains and rated voltage, current, power factor: P1 = U × I × cosφ where: • P1 [W] is rated...

GENER AL PURPOSE 1-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...
