Equipping a pump test facility for variable speed operation can provide greater flexibility and expand opportunities to evaluate pump performance.

Emplear velocidad variable durante las pruebas puede brindar mayor flexibilidad y ampliar las oportunidades para evaluar el rendimiento de las bombas.

While highly effective for control, pulse width modulation introduces high-frequency transients that can compromise motor reliability if left unchecked.

Si bien es muy eficaz para el control, la PWM introduce transitorios de alta frecuencia que, si no se controlan, pueden comprometer la confiabilidad del motor.

This article explains that not all inverter-rated motor windings offer the same level of protection when operating with variable-frequency drives (VFDs), particularly when comparing motors built to NEMA and IEC standards. While maintenance teams increasingly source motors globally, assuming all inverter-rated motors perform similarly can lead to premature failures in converter-fed applications.

Este webinario cubrirá los fallos asociados con los motores trifásicos accionados con variadores electrónicos de frecuencia (VFDs) y como rebobinarlos, rebajando las posibilidades de fallos futuros.

Variable frequency drives (VFDs) are more common than ever before.  Sometimes when a VFD is introduced into a motor driven system, system reliability suffers. This recording addresses some of the common factors that reduce motor driven system reliability and how to correct them.   

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.
