Frequently asked questions (FAQ) 

What standards govern motor testing?

Motor testing is commonly performed in accordance with international standards such as the IEC/EN 60034 series and UL 1004 series. Applicable standards depend on the motor type, application and target market. 


What is the importance of inverter testing?

Inverter testing is important to address power-electronics-specific risks such as EMC emissions, insulation coordination and thermal performance. It helps ensure safe operation, regulatory compliance and reliable system performance.

How early should testing be considered in the product lifecycle?

Testing should be considered as early as the design and development phase. Early testing helps identify risks, reduce redesign effort, and accelerate time to market.
