IEC -0:8 / IS 615-011 Specifications International Electro technical Commission (IEC) standard IEC -0:8 defines energyefficiency (IE code) classes for single speed,three-phase,50 and 60 Hz induction motors. The efficiency levels defined in IEC -0 are based on test methods specified in IEC --1:7 The standard defines three International energy efficiency classes (IE classes). - IE1 = Standard efficiency (EFF in the former European classification scheme) - IE = High efficiency (EFF1 in the former European classification scheme and equivalent to EPAct in the USA for 60 Hz) - IE = Premium efficiency (equivalent to NEMA Premium in USA for 60 Hz) The standard covers almost all motors (for example standard,marine,brake motors,geared motor) - Single speed,three-phase,50 Hz and 60 Hz -, or 6 poles - Rated output from 5 to 75 kw - Rated voltage up to 00 V - Duty type S1 (continuous duty) or S (intermittent periodic duty) with a rated cyclic duration factor of 80 percent or higher - Capable of operating direct online The following motors are excluded from the standard : -Motors made solely for converter operation. -Motors completely integrated into a machine (for example,pump,fan or compressor)that can not be tested separately from the machine. -Motors rated for duty cycles S and above except if an equivalent S1 duty is specified by the driven equipment manufacturer. Additional Specifications of IS 615-011 The motors are capable of delivering rated output with, a) terminal voltage differing from its rated value by not more than ± %,or b) frequency differing from its rated value by not more than ± 5%,or c) the sum of absolute percent variations of (a) & (b) not exceeding % The fixing dimensions and shaft extensions of motors are conforming to the values specified in IS 1 and IS. The relationship between output,in k W and frame number are according to IS 1. Apart from efficiency,indian Standard defines following performance parameters for IE motors 1) Full load Speed ) Full load Current ) Breakaway Torque ) Breakaway Current IEC --1:7 / IS 15999 (Part / sec 1) Specification The standard introduces new rules concerning the testing methods to be used for determining losses and efficiency. It offers two ways of determining efficiency; the direct and indirect methods. The standard specifies the following parameters for determining efficiency using the indirect method: 1) Reference temperature ) Four options for determining PLL (additional load losses): a. Measurement- PLL calculated from load tests b. Estimation- PLL at assigned value.5% -1.0% of input power at rated load between 0.1 kw and 00 kw c. Mathematical calculation - Eh star -alternative indirect method with mathematical calculation of PLL d. PLL from removed rotor and reverse rotation test Winding losses in stator and rotor are determined at (5º C + actual temperature rise measured) The resulting efficiency values differ from those obtained under the previous IEC testing standard, IEC -:1996. It must be noted that efficiency values are only comparable if they are measured using the same method.

For these reason the starting performance of energy efficient motors differs somewhat from motors with a lower efficiency. On average the locked rotor current increases by %-15% for motors from one energy efficiency class compared to motors of the next higher class with the same output power. Individually,this difference depends on the construction princi ple of the motor and should be checked with manufacturer when replacing motors in an existing installation. It must be ensured that the control protective device is properly sized and setup. 6) 5,5 7,5 11 15 18,5 0 7 5 55 75 90 1 1 160 15 55 75 Output kw NOTE :1) It must be noted that efficiency values are only comparable if they are measured using the same method. ) As per IEC-0 : 8 motors specially designed, For special requirement of the driven machine (e.g heavy starting duty, special torque stiffness and/or breakdown torque characteristics, large number of start/stop cycles,very low rotor inertia) For special characteristics of grind supply (e.g limited starting current, high tolerances of voltage and/or frequency) For special ambient conditions (e.g very low ambient temperature,smoke extraction motors, high altitues of installation)

APEX SERIES ENERGY & CO ISSUES Most electricity today is generated by burning fossil fuels and producing steam which is then used to drive a steam turbine that in turn,drives an electrical generator. More serious are concerns about the emissions that result from fossil fuel burning. Burning them results in the conversion of carbon to carbon dioxide, which is then released into the atmosphere. The estimated CO emission from the world s electrical power industry is billion tonnes yearly. This results in an increase in the Earth s levels of atmospheric carbon dioxide, which enhances the greenhouse effect and contributes to global warming. The linkage between increased carbon dioxide and global warming is well accepted though fossil-fuel producers vigorously contest these findings. Estimates of Technical Savings Total Energy & Feedstock Savings Potential EJ/yr Mtoe/Yr % Mt CO/yr Sectoral Improvement Chemical / Petrochemicals Iron and steel Cement Pulp and Paper Aluminium Other non-metalic metals Minerals and non-ferrous System/life cycle improvement Motor System Combined head and power stem system Process integration Increased recycling Energy Recovery Total Global improvement potentialshare of industrial energy use and CO emissions According to Environment Canada : Fossil fuel-fired electric power plants emit carbon dioxide, which may contribute to climate change. In addition, the sector has significant impacts on water and habitat and species. In particular,hydro dams and transmission lines have significant effects on water and biodiversity Here are some more starting predictions of what changes to climate could cause,and how we ll be affected: Low-High Potential Major floods may now start to happen every or 0 years rather than once or twice a century Global sea levels could rise by almost a meter by 0 Exposure to higher levels of UV light could cause an extra 5,000 deaths a year from skin cancer Climate change may drive more of a quarter of land animals and plant species to extinction Total energy & Feedstock Savings Potentials The conclusion is that manufacturing industry can improve its energy efficiency by an impressive 18 to 6%,while reducing the sectors CO emission by 19 to %,based on proven technology. Identified improvement options can contribute 7 to % reduction in global energy and process-related CO emissions. The single most important category is motor systems, followed by chemicals/petrochemicals on an energy savings basis. The highest range of potential sectoral savings for CO emissions is in cement manufacturing. The savings potential under the heading system/life cycle improvements is larger than the individual sub-sectors in part because those options apply to all industries. 5.0-6.5.-.5.5-.0 1.- 0.-0. -55 55-8 60-7 1-6 7-70-70 0-60 80-50 5-5 0-0 1-16 9-18 8-15-18 6-8 0.5-1.0-0-70 1-5 6-8 - -.5 1-.5 -.5 -. 5-7 1-191 8-7 6-60 -60 6-60 6-55 -900 0-750 1-170 1-180 70-180 80-80-190 1900-18-6 % 18-6 % 19- % Reference : Tracking industrial energy efficiency and CO emissions Conserve Energy for a Brighter Future..!

APEX SERIES FAQ FREQUENTLY ASKED QUESTIONS 1. What is IE? IE is International Efficiency with class 1, & i.e. IE1, IE & IE. The new standard IEC -0:8/IS615:011 defines these classes. At the same time,with the IEC --1:7/IS615:011 standard,a new procedure for the determination of efficiency has been introduced which also contributes to international harmonization.. This standard is made to unify motor testing procedures, determination of efficiency and product labeling requirements. This is to enable motor user worldwide to easily identify premium efficiency products. New efficiency classes defined by IEC- 0 and its equivalence with other standards/nomenclature Efficiency % 97 95 9 91 89 87 85 8 81 High efficiency Low efficiency IE IE IE IE1 EFF1 EFF Old CEMEP Directive IE Premium Efficiency IE High Efficiency IE1 Standard Efficiency IEC motors IE Classes - pole Output kw NEMA Premium EPAct NEMA motors 0,75 1,1 1,5, 5,5 7,5 11 15 18,5 0 7 5 55 75 90 1 1 160 15 55 75. Why improving motor efficiency is important? Over 70 % of all electrical energy consumed in industries is used by electric motors. Improving the efficiency of electric motors and the driven equipment can save energy,reduce operating costs, and improve our nation's productivity. Energy efficiency should be a major consideration when you purchase or rewind a motor. The annual energy cost of running a motor is usually many times greater than its initial purchase price. For example,even at the relatively low energy rate of Rs.0.085/kWh,a typical 15 kw continuously running motor uses almost Rs.,000 worth of electricity annually,about six times its initial purchase price.. What efficiency values should I use when comparing motors? When comparing motor efficiencies,be sure to use a consistent measure of efficiency. Nominal efficiency is best. Nominal efficiency is an average value obtained through standardized testing of a population of motors. Minimum guaranteed efficiency, which is based on nominal efficiency, is slightly lower to take into account typical population variations. Minimum guaranteed efficiency is also less accurate, because the value is rounded. Other efficiency ratings, including apparent and calculated, should not be used... When should I consider buying an energy-efficient motor? Energy-efficient motors should be considered in the following circumstances: For all new installations - When purchasing equipment packages, such as compressors, HVAC systems, and pump - When major modifications are made to facilities or processes - Instead of rewinding older, standard efficiency units - To replace oversized and under loaded motors - As part of a preventive maintenance or energy conservation program. 5. Should I rewind a failed motor? Although failed motors can usually be rewound, it is often worthwhile to replace a damaged motor with a new energy-efficient model to save energy and improve reliability. At the time of calculating operating costs for rewound motors, deduct one efficiency point for motors exceeding 0 kw and two points for smaller motors. Have motors rewound only at CG authorized service centers that use low temperature bake out ovens,high quality materials,and a quality assurance program based on ISO-9000. Ask the repair shop to conduct a core loss or loop test as part of their rewind procedures. Select a new energy-efficient motor under any of the following conditions: - The motor is less than 0 kw - The cost of the rewind exceeds 65% of the price of a new motor. - The motor was rewound before year 0 6. What design factors should I consider when choosing a new motor? Motor size- Motors should be sized to operate with a load factor between 65% and 0%. The common practice of over sizing results in less efficient motor operation. For example,a motor operating at a 5% load is less efficient than a smaller motor that is matched to the same load. Of course,some situations may require over sizing for peak loads,but in such cases alternative strategies should be considered,such as a correctly sized motor backed up with a pony motor. Operating speed- Replacement is to done by energy efficient motors with a comparable full load speed for centrifugal load applications (pumps and fans). Induction motors have an operating speed that is slightly lower than their rated synchronous speed. For example,a motor with a synchronous speed of 1500 rpm will typically operate under full load at about rpm. Operating speed (full-load rpm) is stamped on motor nameplates. The difference between the synchronous speed and the operating speed is called slip. Slip varies with load and the particular motor model. Every pump and fan has a designed speed. Centrifugal pump and fan loads are extremely sensitive to speed variations; an increase of just 5 rpm can significantly affect the pump or fan operation, leading to increased flow, reduced efficiency, and increased energy consumption. Whenever a pump or fan motor is replaced,be sure to select a model with a full-load rpm rating equal to or less than that of the motor being replaced. Inrush current- Avoid overloading circuits. Energy-efficient motors feature low electrical resistance and thus exhibit higher inrush currents than standard models. The inrush current duration is too short to trip thermal protection devices, but energy-efficient motors equipped with magnetic circuit protectors can sometimes experience nuisance starting trips. 7. How to calculate energy savings and payback period? 5.5 kw pole standard IE1 motor is having efficiency 8.7 %. Where as Apex Series IE has 87.7 % Energy Savings (S) * Payback Period (P) * = W X L X C X N X( 0/Es-0/Ee) = 5.5 X 1 X 5.8 X 800 X (0/8.7-0/87.5) = 5785 per year = Ce/S X =.6 months W-Motor Rating in kw L-% load (1 for rated kw loading) C-Electricity Cost /kwh N-Number of working Hours per year * This may vary with the application and working hours Ee-Efficiency of IE motor Es- Efficiency of standard IE1 motor Ce-Cost of IE motor- Cost of IE1 motor i.e.(5-11111= ) 0
