Weg (Marathon) Crane Motor IE2 & IE3

Overview

Marathon Electric introduces VD series motors tailor made for inverter drives having enhanced dielectric strength and adequate thermal margin suitable for variable speed application. PWM technology involving high switching frequency IGBT drives has enabled AC induction motors to be operated as variable speed drives. However, there had been a documented increase of premature winding failure for standard general purpose motors when operated with inverter drives.
