The open stator impedance test (a.k.a, ball test or dummy rotor test) is used by many service centers as a quality control check before winding treatment and/or a troubleshooting test. This webinar recording reviews test procedures, expected outcomes and incorporating thermal camera imaging.

Explore key mechanical factors when converting a horizontal motor to vertical orientation.

There are heat methods and press methods for straightening shafts. This webinar reviews those methods, their pros and cons, and when one method or another may be applicable.

This webinar discusses specific procedures to obtain the best possible results when machining & undercutting commutators for DC machines.

This presentation discusses the importance of tracking rework in the shop and how it can lead to focused training opportunities, improved turnaround times and improved profitability.

Las pruebas de Resistencia de Aislamiento, Relación de Absorción Dieléctrica (DAR) e índice de Polarización (IP) son herramientas comúnmente usadas para evaluar la condición del aislamiento de las máquinas eléctricas rotativas y para confirmar la integridad del sistema de aislamiento a tierra, detectando la presencia de humedad que puede ocasionar fallos en los devanados. En las máquinas grandes, un adecuado análisis de tendencias ayuda a detectar cambios importantes y a tomar acciones correctivas antes de que ocurran fallos catastróficos.
