This update addresses the global low-voltage (LV) motor and variable-speed drive (VSD) markets, with a discussion of systems efficiency. It provides market revenues and units with supporting qualitative analysis regarding changes in manufacturing, distribution, and other technological advancements.

There are changes in the National Electrical Code that EASA members need to know about. View this webinar to learn:

• The background behind these changes
• The 2020 change impacting reconditioned motors
• How the changes will be interpreted
• What the changes mean for the electric motor service industry

High-potential testing is routinely used to assess the ground insulation of AC stator windings in-process, after completion of a rewind and post-delivery. This webinar covers types of high-potential tests, testing standards, evaluating test results, and more.

La conexión incorrecta de los motores eléctricos es una causa frecuente de fallo y es más común de lo que parece. La falta de información y la mala interpretación de los datos de placa son algunas de sus causas. En este webinario se explican los diferentes tipos de conexiones para los motores eléctricos trifásicos de una o varias velocidades con al menos 6 cables de salida y se comparan las equivalencias NEMA e IEC para el marcado de cables. La información proporcionada también será de gran utilidad para evitar el conexionado incorrecto en los diferentes voltajes. También incluye las conexiones por devanado partido (Part Winding) y como interpretar la información de la conexión de la placa de datos.

The physical air gap between the rotor or armature and the stator or field frame is complex and plays a critical role in the performance of AC and DC machines. Most repairers do not realize how little they understand about this subject.

This recording will help you get organized using the “5+1 S Series.” Learn how each “S” can help you with a path to productivity by becoming more efficient, or lean.

This webinar recording discusses:

• Temperature rise (Method of detection, Insulation class, Enclosure, Service Factor)
• Increasing winding life (Insulation class, Cooling system, Winding redesign)

This webinar recording covers:

• Shaft material and specs
• Shaft coupling types
• Machining for shafts
• Bronze, plastic, graphite and cutlass bearing options
• Bearing clearance concerns and reference data 
• Bearing housing fits

This webinar demonstrates an easy-to-build temporary oven that can be constructed in the service center or in site.

The topics covered included in this webinar recording:

• One circuit wye connection — Best , no parallel paths, turns per coil may prevent this
• Delta or multiple parallel circuits—Produces closed circuits, Circulating currents
• Open delta (4 wire connection)
• Permissible connections—Skip pole, adjacent pole
• Determined by speed combination
