idéntica a la US381968, con algunas
modificaciones menores para formalizar
su afirmación de haber inventado
un sistema de transmisión de potencia
además de un motor. El documento
US381968 se utilizará aquí para representar
a ambos. El cuarto documento
es el de Tesla de 1888 del AIEE, " A
New System of ac Motors and Transformers "
(Un sistema nuevo de motores
y transformadores de CA). En este
documento, presenta sus inventos relacionados
con los motores polifásicos.
Estos documentos contienen dos frases
clave que resumen sus afirmaciones
sobre los motores: polos giratorios o
cambiantes y motor de inducción. Un
análisis detallado de estas frases nos
ayudará a entender lo que Tesla sabía
sobre el motor de inducción y cómo debía
funcionar.
Se reconoce que Tesla patentó el
campo magnético giratorio. En sus primeros
trabajos, no utiliza esa frase. En
el documento US381968, página 4, línea
43, Tesla dice que " una rotación del
generador produce un desplazamiento
progresivo de los polos del motor " .
También utiliza esta misma fraseología
en el documento US382279, página 1,
línea 14, y en su trabajo del AIEE en
1888, en la página 312. No obstante,
está claro que Tesla se refiere a lo que
más tarde se conocería como campo
magnético giratorio.
Es habitual asociar el nombre de
Tesla con el motor de inducción. Sin
embargo, no se menciona la frase " motor
de inducción " en ninguna de estas
tres patentes ni en su documento del
AIEE. En el documento US381968,
página 2, línea 95, Tesla se refiere a
su figura 9 (figura 8 en este artículo)
donde dice: " El disco D, debido a su
tendencia a adoptar aquella posición
en la que abarca el mayor número posible
de líneas magnéticas, se pone
en rotación, siguiendo el movimiento
de las líneas de los puntos de mayor
atracción " . Continúa en la página 2, línea
105, " Este fenómeno lo atribuyo a
una cierta inercia o resistencia inherente
al metal al rápido desplazamiento de
las líneas de fuerza " . Y en la página 4,
línea 40, Tesla afirma: " El movimiento
