Introduction

Global warming is a reality and world over people are working towards reduction in carbon foot print.

Electric motor applications, in Indian industry, consume about seventy percent of the generated electrical energy. Improving

efficiency of the motor is therefore a major concern in energy-efficiency efforts.

Electric motors with improved efficiency, in combination with frequency converters can save about 7% of the total worldwide

electrical energy. Roughly one quarter to one third of these savings come from the improved efficiency of the motor.

A need was felt amongst users, consultants and manufacturers in India to revise existing BIS standard IS 12615:2004 to harmonize

with the international standards. This will lead us to be in line with international code of standards and practices. This will also

result in having uniform test procedures to facilitate the end user to compare the performance and energy efficiency of motors.

Motors from 0.37kW to 375kW make up the vast majority (approximately 90%) of installed motor population and are covered

by the standard IS 12615:2011. This fulfills the need of the manufacturers to design motor for a global market. This standard

defines four efficiency classes for nominal frequency 50Hz.

Salient features of BIS standard IS 12615:2011 (second revision)

This standard is primarily based on IEC 60034-30:2008 issued by the International Electrotechnical Commission except that

additional performance parameters other than efficiency values have also been included.

The efficiency levels in IS 12615:2011 are based on test methods specified in IS 15999 (Part 2/sec 1):2011 / IEC 60034-2-1:2007.

The standard specifies methods used to determine losses and efficiency, with the objective to calculate efficiency values

more accurately.

New IE efficiency classes are as given below

Efficiency Class Description

IE1 Standard efficiency Comparable to eff2

IE2

IE3

IE4

High efficiency Comparable to eff1

Premium Premium

Super premium Super premium

As per the standard, efficiency class of IE4 is under consideration and would be incorporated later. The standard IS 12615:2011

covers low voltage, AC three phase squirrel cage, single speed induction motors for

Rated voltage

Energy efficient cage-induction motors are typically built with more active material to achieve higher efficiency and hence

the starting performance of these motors differ somewhat from motors with a lower efficiency. The locked rotor current

increases approximately by 10 to 15 percent for increase in each level of efficiency for the same output power. For replacing

existing motors, this should be checked by the user with manufacturer for proper sizing of the protective devices.

Old efficiency levels were Eff2 and Eff1 (as per CEMEP). For calculation of these efficiencies, fixed stray load losses (0.5%

of motor output) were assumed. Now IS 12615:2011 refers to IS 15999 (Part 2/sec 1):2011 / IEC 60034-2-1:2007 for calculation

of efficiency. This calculation is based on the new methods of stray load loss measurement specified in the standard.

The effect is in the reduction of efficiency as compared to the earlier values.

Bharat Bijlee IE2 motors suitable to run with VFDs

Bharat Bijlee offers the entire range of motors suitable to run

with VFDs.

Motors are suitable for :

Constant torque application like crane, hoist, reciprocating

compressor etc.

Variable torque application like centrifugal pump, fan,

blowers etc.

Constant power application like metal cutting lathes, wire

winding machines etc. and are custom built to suit

customer's requirements.

Motors for constant torque application suitable for speed range

of 1:10, 1:5, 1:2 etc can be provided. Depending on the speed

range, motors can be offered with forced cooling

(IC416) or in higher frame sizes 132S and above. Please

check with our sales office, for motors to be operated above

1.5 times the synchronous speed.

PWM, IGBT devices operate at very high frequencies (2 kHz to

15 kHz) and have very short rises times leading to high dv/dt.

Longer cable lengths also contribute to higher voltages

at the motors terminals due to standing wave phenomenon.

These stress the insulation of the motors. Bharat Bijlee motors

are provided with special impregnation system /vacuum

pressure impregnation and dual coated winding wire to take

care of these stresses. This insulation conforms to the

requirements given in IEC 60034-18-41. For voltage higher than

500 V, refer to our sales office.

All the motors are provided with six terminals in the terminal

box. Shaft induced voltage occurs due to the use of VFD. This

causes flow of currents through bearing which can lead to

premature bearing failure. Insulated bearings can be provided

in frames from 132S onwards on request.

In closed loop system operations, speed feedback is obtained

through encoder mounted on the shaft of the motors. We

provide encoder mounting arrangements on Non Drive End

side shaft of the motors on request.

For further details and technical offer, please refer to our Sales

office in your area.

Payback Calculations:

Effect of additional stray load losses for efficiency determination as per IS 12615-2011

The new standard follows IS 15999 / IEC 60034-2-1 for arriving at the stray load losses. These losses can vary from 2.5%

in small motors to 0.5% in higher ratings up to 1MW. The earlier standard IS 12615-2004 used for eff1 motors assumed stray

losses as 0.5% of output. Hence the efficiency values tested by the earlier standard would be 0.5% to 1.5% higher than

the new standard for the same motor.

Example is as given below

When comparing eff1 motor & IE2 motor, it is necessary to note the difference in testing methods. The standard has

reduced the efficiency value to take care of this. At first glance a customer would feel that an IE2 motor is inferior to an

Eff1 motor though both might be identical.

Hence for any comparison, it is necessary to use the same method of loss calculation. The worked out example shown below

gives the energy savings per year (for 8000 hours running) of a Bharat Bijlee IE2 motor (normalized for 0.5% stray loss) over a Bharat

Bijlee standard IS 325 motor
