What is efficiency in electric motors? And how does it impact your company's budget

In the industrial world, the word "efficiency" is synonymous with productivity, savings, and sustainability. When we talk about electric motors, this concept gains even more relevance. But in practice, what does it mean to say a motor is efficient?  

Objectively, the efficiency of an electric motor represents its ability to transform the electrical energy consumed into useful mechanical energy. No motor is 100% efficient, as there are always losses in the process. The key difference lies in minimizing these losses, thereby increasing the equipment's performance index. 

The villains of efficiency: Where does the lost energy go?

The losses of an electric motor can be divided into two main categories: 

• Electrical losses: occur in the windings (Joule losses) and in the iron of the magnetic core (magnetic losses). These losses primarily manifest as heat. 

• Mechanical losses: are caused by friction in the bearings and air resistance in the ventilation system, which is essential for cooling the motor. 

A high-performance motor is one designed with materials and technologies capable of reducing these losses as much as possible.

Why is efficiency an investment, not a cost?

Opting for high-performance motors from Mercosul brings direct benefits on three main fronts: 

• Reduction of operational costs: efficient motors consume less electrical energy to perform the same work. In continuous operations, this difference represents significant savings over the year. 

• Sustainability: less energy waste means a smaller carbon footprint. A factory with efficient motors contributes to environmental goals and to building a more responsible brand. 

• Longer lifespan and reliability: by losing less energy as heat, the motor operates at lower temperatures. This reduces wear on bearings, insulators, and other components, extending the durability and reliability of the operation.
