This presentation covers induction motor basics for squirrel-cage and wound rotor motors.

This presentation stresses the importance of taking accurate winding data and explains and emphasizes the consequences of inaccurate data. One of the main benefits of this presentation is to improve ability to “get it right the first time” to avoid the added cost and time of another rewind to correct errors.

This presentation reviews procedures that explain how to identify unmarked leads of three-phase motors with one or two windings.

Learn how to effectively use EASA's live, ever-expanding online database of more than 250,000 windings.

This article explains in layman’s terms what electromechanical professionals refer to as circulating currents, why they exist in three-phase electric motors and to offer practical solutions. 

Este artículo es explicar en términos sencillos a qué se refieren los profesionales de la electromecánica como corrientes circulantes, por qué existen en los motores eléctricos trifásicos y ofrecer soluciones prácticas.

When preparing to rewind random or form-wound status, sometimes there just doesn’t seem to be enough room in the stator slot for the desired conductor area and insulation quantities. This presentation looks at balancing stator copper losses against insulation reliability.

This article looks at some of the import details for a proper concentric to lap winding conversion. It also shows how using the EASA Technical Manual, EASA's AC Motor Verification & Redesign Software, as well as the EASA AC Redesign manual, can help.

Este artículo analiza algunos de los detalles de importación para una conversión adecuada de devanado concéntrico a devanado por vuelta. También muestra cómo puede ayudar el uso del Manual técnico de EASA, el software de rediseño y verificación de motores de CA de EASA, así como el manual de Rediseño de motores AC de EASA.

EASA recommends using the lead wire specified by the original equipment manufacturer (OEM) whenever possible. If not available, some guidance is provided in section 6 of the EASA Technical Manual and an online calculator is available to determine a minimum recommended size based on temperature rating, expected current, number of leads and type of connection. This article will describe the calculator’s function.
