Revolutionising energy efficiency

Effective electric motor rewinding practices are vital for enhancing energy efficiency and mitigating carbon emissions.

At the recently concluded COP28, climate finance took the centre stage with a commitment to mobilise over $57 billion and setting the pace for a new era in climate action. The amount of cash needed for the energy transition, climate adaptation and disaster relief are overwhelming and estimated that emerging markets and developing countries will need $2.4 trillion a year in investment to cap emissions and adapt to the challenges posed by climate change.

While the need for finance has been talked much as much needed resource to accelerate the pace of decarbonisation, many of the low hanging fruits still need to be explored and implemented. Ensuring energy efficiency of electric motors through proper rewinding is one such example that promises impactful results without the need for developing any new cutting-edge technology. Instead, it requires a shift in focus towards skill development and service enhancement to make the process more efficient. It is a simple yet effective solution that holds the potential to yield substantial reductions in energy consumption and, consequently, carbon emissions.

Electric motors and motor driven systems account for approximately 70% of the electricity consumed by industries and industry accounts for approximately 42% of total electricity consumption in India. Hence, efficiency of electric motors should not be overlooked.

In FY22, India produced around 4.37 million units of industrial LT motors, with a total installed base of 39 million units. However, the average lifespan of these motors varies from 13 to 22 years, depending on the end-user industry. Approximately 12 million LT induction motors were rewound in FY22, constituting 30% of the installed base.
