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.
EASA recomienda usar el cable de salida especificado por el fabricante original del equipo. Si no está disponible, la sección 6 del Manual técnico de EASA proporciona orientación al respecto y hay una calculadora en línea disponible en go.easa.com/calculators para determinar el tamaño mínimo recomendado según la clasificación de temperatura, la corriente esperada, la cantidad de cables y el tipo de conexión. Este artículo describirá la función de la calculadora.
Occasions arise where original winding data is not available. It may have been recorded incorrectly or a different service center may have stripped the core but not completed the repair. In those cases, the service center must come up with a new “bare core” winding design. EASA's redesign software has some specific features to address this need.
Surgen ocasiones en las que los datos de bobinado originales no están disponibles. Es posible que se haya registrado incorrectamente o que un centro de servicio diferente haya quitado el núcleo pero no haya completado la reparación. En esos casos, el centro de servicio debe presentar un nuevo diseño de bobinado de "núcleo desnudo". El software de rediseño de EASA tiene algunas características específicas para abordar esta necesidad.
Choosing an appropriate lead wire for a new stator winding is an important task. The manufacturer’s information is not always available, or the number of circuits or external connection may have been changed, requiring a redesign of the lead wire.
EASA Internal Connection Diagrams for Three-Phase Electric Motors is available to members as a free PDF download and contains hundreds of connections, as well as templates for windings up to 30 poles. This webinar recording shows how to access it and provide examples of how to use it.
Este webinario ayudará a los centros de servicio a navegar a través de los aspectos fundamentales del rediseño de motores de CA y ayudará a prevenir errores costosos asociados a los rediseños incorrectos.
En este webinario explicaremos como los diferentes cambios efectuados en el bobinado impactan en el desempeño del motor. Si no es realizado de forma correcta, cualquier cambio en el bobinado podría llegar a tener consecuencias negativas.
This webinar recording shares some of the “best practice” rewind methods used by (and learned from) EASA service centers around the world: connection recognition, best insulating materials, wire choices and tips to save time and effort.
With a steady increase in random wound AC motor sizes and the obvious superiority of the form coil winding, one area where we can help improve customers' motor reliability is by redesigning those large random wound motors to accept form coils. Most repairers would agree that machines rated larger than 600 hp (450 kW) should be designed as form coil machines. Likewise, those rated over 2 kV will be much more reliable as form coil machines.
No one wants to rewind a motor using 60 #14 AWG (62- 1.6 mm) wires in hand. With an abundance of niche suppliers of stator laminations, the cost and practicality of converting a random wound motor to form coil are available to nearly all service centers. Replacement laminations can be punched, laser-cut or water-cut, and supplied with very reasonable delivery times.
This 40-page booklet provides great advice for obtaining the longest, most efficient and cost-effective operation from general and definite purpose electric motors.
