Aunque la tracción magnética desbalanceada puede afectar a otras máquinas eléctricas rotativas, como los motores y generadores de CC y monofásicos, nuestro enfoque en este artículo se centrará en los motores jaula de ardilla trifásicos. Los dos temas principales son: La tracción magnética desequilibrada (UMP) y el descentrado del rotor (pullover).

Relevant standards including IEC 60085 and IEEE 1 have similar definitions for electrical insulating materials (EIM) and electrical insulation systems (EIS). As with any system, there is an interaction between the materials used, and the insulation system developers take great care to ensure that this interaction does not lead to undesirable outcomes.

Diferentes normas relevantes incluyendo la IEC 60085 y la IEEE 1 definen de forma similar los materiales electro aislantes (EIM) y los sistemas de aislamiento eléctrico (EIS). Como en cualquier sistema, existe una interacción entre los materiales usados y los diseñadores de los sistemas de aislamiento cuidan todos los detalles para evitar que esta interacción produzca resultados indeseados.
