In today’s global economy, it is quite possible to get electric motors from all over the world. Most electric motors that are 500 hp (373 kW) or less will conform to one of two basic manufacturing standards; NEMA or IEC. The intent of this article is to focus on IEC standards for managing voltage stress in VFD applications as it pertains to the motor’s windings.

En la economía global actual, es posible adquirir motores eléctricos fabricados en todo el mundo. La mayoría de los motores eléctricos de 500 HP (373 kW) o menos se ajustarán a una de las dos normas básicas de fabricación; NEMA o IEC. La intención de este artículo es centrarse en las normas IEC para gestionar la sobre tensión en aplicaciones con VFD en lo que respecta a los devanados del motor.

This webinar goes through the basics of what accessories may be needed for proper VFD control and power quality add-ons to improve motor driven system reliability.
