Highly dynamic test benches for electric motors
Performance, endurance and compliance
Develop and validate your electric powertrains under the most extreme test conditions
The Emitech Group offers a comprehensive platform of high-dynamic test benches dedicated to electric motors (e-motors). Designed to meet performance, endurance and regulatory qualification requirements, our resources are aimed at R&D engineers, electromobility project managers and GMP validation managers in the automotive and aerospacesectors.
Our infrastructure allows us to test and characterise the entire electrified powertrain under representative operating conditions, combining power, high rotational speed, measurement accuracy
