Three-phase motor

single-phaseACasynchronous

Overview
AC external-rotor motors from ZIEHL-ABEGG provide a compact drive solution for ventilation and industrial applications. When controlled by a frequency inverter, partial-load energy efficiency is improved. The external-rotor design combines a space-saving layout with a proven wear-free squirrel-cage drive concept. Integrated or external inverters and EC controllers enable tailored drive solutions.
