Induction motor Energy Efficiency

The Central Scientific Instruments Organization, part of CSIR, has come up with a system for monitoring efficiency of induction motors in the field. This is a big deal, because induction motors are the largest consumers of electricity and are used everywhere—fans, compressors, pumps, conveyors, winders, mills, elevators and several home appliances. It is very necessary to conserve energy by running the motors efficiently.  

Measuring the efficiency of motor on-line helps in identifying the motors for Refurbishment, Replacement with new motor, Checking the efficiency after rewinding, Preventive maintenance Operating the motor around its Best Efficiency Point etc. 

The user industries know this—hence there is a big market for induction motor efficiency monitoring systems. Hence it is an opportunity for small scale industries to manufacture and market these systems with CSIO technology. 

CSIO says the system has been tested in several large industries such as Ramco Cements and BHEL and the feedback has been overwhelmingly positive. According to CSIO, the users have said that the system is “very user friendly, simplicity in connecting the IMEMS unit to the Motor under study, compactness and more importantly the motor under study need not to be detached from the load/pump.” The system is used by field engineers. By installing this IMEMS instrument by closely monitoring and analyzing the data and taking corrective actions like timely replacement which makes the motors to run more effectively. 

CSIO’s IMEMS system uses sets of data (voltage, current, power and speed) measured from the motor (on-site) as input to the developed algorithm ( Refined form of Equivalent Circuit Method) for evaluating the motor parameters instead of using traditional no-load and blocked rotor tests. The estimated parameter using the developed algorithm is used for determining the onsite efficiency of the motor. The developed system can be used to operate the motor at its Best Operating Point (BOP).
