1 NEW EFFICIENCY STANDARD PRESENTATION BY Bhalchandra Bansod Regional Manager-Industrial

2 INDIAN STANDARS SCENARIO INDIAN STANDARS SCENARIO IS8789(1978, REVISED 1998) IS SUPERCEDED BY IS12615(1996, REVISED 2004) IS8789(1978, REVISED 1998) IS SUPERCEDED BY IS12615(1996, REVISED 2004) IS8789 MOTORS ARE NOT MANUFACTURED BY REPUTED MANUFACTURERS IS8789 MOTORS ARE NOT MANUFACTURED BY REPUTED MANUFACTURERS IS12615 PRESENTLY USES IEC EFFICIENCY MEASUREMENT METHOD. IS12615 PRESENTLY USES IEC EFFICIENCY MEASUREMENT METHOD. IS12615 IS JUST REVISED EFFECTIVE JUNE 2011 IS12615 IS JUST REVISED EFFECTIVE JUNE 2011 REVISED STANDARD USES IEC METHOD OF EFFICIENCY MEASUREMENT. REVISED STANDARD USES IEC METHOD OF EFFICIENCY MEASUREMENT.

3 TOMMORROWS EFFICIENCIES TOMMORROWS EFFICIENCIES IS IS IE1Eff2 IE2Eff1 IE3Premium Eff IE4Super Premium

4 Efficiency Comparison across the Globe

5 EFFICIENCY MEASUREMENT IS APPROXIMATE EFFICIENCY MEASUREMENT IS APPROXIMATE

6 EFFICIENCY MEASUREMENT METHOD Motor Loaded by Generator Motor Loaded by Generator Input given equal to output by Name plate efficiency Input given equal to output by Name plate efficiency Stator resistance is measured to calculate Stator copper loss Stator resistance is measured to calculate Stator copper loss Slip is measured to calculate rotor copper loss Slip is measured to calculate rotor copper loss Friction and windage loss assumed as 1% of output Friction and windage loss assumed as 1% of output Stray Loss assumed as 0.5% of Output. Stray Loss assumed as 0.5% of Output. Input-losses=Output and Output/Input=Efficiency Input-losses=Output and Output/Input=Efficiency

7 NEW STANDARD ASSUMES MUCH HIGHER STRAY LOSSES Stray load losses are due to Magnetic transfer loss in the air gap between the stator and rotor

INCLUSION OF 6 POLE MOTORS INCLUSION OF 6 POLE MOTORS REVISED PUBLICATION IN JUNE 2011 REVISED PUBLICATION IN JUNE 2011 PROPOSED WITHDRAWL OF IE1- JAN 2012 PROPOSED WITHDRAWL OF IE1- JAN 2012 PROPOSED WITHDRAWL OF IE2- JAN 2014 PROPOSED WITHDRAWL OF IE2- JAN 2014 INTRODUCTION OF IE3- JAN 2014 INTRODUCTION OF IE3- JAN 2014 INTRODUCTION OF IE4- TO BE DECIDED INTRODUCTION OF IE4- TO BE DECIDED

9 Super E Gives Better Part Load Efficiencies. Nema Super E compared with Eff2

10 Upgrading even one, 1 kW motor to a Premium Efficient motor gives double benefit of Energy Savings and Carbon credits..IN PAT.. Every year will eliminate: 1 Drum of Oil from being burned 250 Kg of coal from being burned Up to 800 gms. of carbon emissions from being released into the atmosphere and.... or....

11 PREMIUM EFFICIENCY INSIDE High Quality Ball Bearing, reduce friction and vibration Patented Lube-Lok retainer grease seal on both end Locked bearing reduces endplay and minimizes energy loss in axial movement How to improve motor Efficiency and provide longer life? FRICTION LOSS REDUCTION

12 PREMIUM EFFICIENCY INSIDE Fan & Fan cover designed for optimum cooling and quieter operation Smaller fan generate less losses Smaller fan can be used due to cooler operation How to improve motor Efficiency and provide longer life? WINDAGE LOSS REDUCTION

13 PREMIUM EFFICIENCY INSIDE More Wire volume More Wire volume Improved slot design Improved slot design ISR (Inverter Spike Resistant) magnet wire is up to 100 times more resistant to voltage spikes ISR (Inverter Spike Resistant) magnet wire is up to 100 times more resistant to voltage spikes End turns laced both end End turns laced both end Low temp. raise (< 80°C) Low temp. raise (< 80°C) Class F insulation systems Class F insulation systems Each 10°C below max allowed temperature double insulation life Each 10°C below max allowed temperature double insulation life How to improve motor Efficiency and provide longer life? STATOR COPPER LOSS REDUCTION

14 PREMIUM EFFICIENCY INSIDE Improved Rotor insulation High-pressure die cast aluminum Rotor Rotor dynamically balanced to IEEE 841 vibration limits as standard (0.08 in/sec). This reduces energy losses in vibrations. How to improve motor Efficiency and provide longer life? ROTOR LOSS REDUCTION

15 PREMIUM EFFICIENCY INSIDE Thinner lamination Thinner lamination Improved steel properties for lower losses and also allow same performance after rewind Improved steel properties for lower losses and also allow same performance after rewind Optimized air gap. (Hardened and thicker inside shaft) Optimized air gap. (Hardened and thicker inside shaft) More steel - Longer stack More steel - Longer stack How to improve motor Efficiency and provide longer life? IRON AND STRAY LOSS REDUCTION

16 What Motors To Replace Non Branded Non Branded Old motors having no efficiency written on name plate(IS8789) Old motors having no efficiency written on name plate(IS8789) New motors having lower efficiecy on name plate New motors having lower efficiecy on name plate Motors which are rewound more than once.
