Description
Magnetek actuators are electro-hydraulic devices which combine all the basic elements of a hydraulic system into one integral unit, consisting of an electric motor driving a hydraulic pump, piping, working cylinder and piston.
The function of the actuator is to convert electrical energy into a mechanical force hydraulically, producing a smooth straight line thrust, throughout the piston stroke. They are mainly used to release spring-set brakes like the MBT, MST and SDT.
Three types of actuators are available:
AC three phase (Ed type)
AC three phase explosion-proof (EdF type)
DC (Eg type)
Magnetek offers the Ed type of 60 Hz actuator in 208VAC, 230/460VAC and 575VAC three phase versions. Other voltages from 110VAC to 690VAC, 50 Hz versions, explosion proof and DC (220VDC) actuators are available with longer lead times.
