What Our Customers Say

Hear from our satisfied customers who have experienced the quality and value of our services.

★★★★★

The design and development of advanced electric motors requires a multi-disciplinary design approach where electromagnetic, mechanical and thermal engineering are brought together to create competitive, optimized products. At Leroy Somer, we have achieved this through internal training programs and a strong leverage of our Romanian design teams.

Over the years we have developed a position of strength in mechanical and thermal engineering in collaboration with 4MULTIPHYSICS SRL. They have now become our reference partner for mechanical structural and vibration and thermal computational fluid dynamics (CFD). Their intimate knowledge of our electric machine products enables them to quickly engage complex finite element calculations, thus avoiding a long learning curve for each new project. Application knowledge further enhances this capability to bring added value to our OEM customer projects.
