Striving to meet IE3 Motor Standards

_____________________________________

South Africa is aligning with global energy efficiency trends through the adoption of IE3 motor standards — a major step toward sustainability and performance.

IE3 (Premium Efficiency) motors are designed to reduce energy consumption, cut operational costs, and improve reliability in industrial applications.

With electricity costs and environmental concerns on the rise, these motors help businesses operate smarter, cleaner, and more cost-effectively.

STM Riduttori South Africa, with NeriMotori, our Italian manufacturer of electric motors is embracing IE3 standards.

We are moving closer to international best practices — supporting both economic growth and a greener future.
