Hy-Thrust Actuators

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.

Standard Features:

• Fast response - 2000 cycles per hour
• Long service life with minimum maintenance
• Extending forces from 50 lbs. to 900 lbs.
• Strokes from 2 to 7.8 inches
• Can be stalled at any stroke position without damage.
• Operating ambient temperature -25°C to +50°C with standard fluid (other ranges available on request)
• Class F insulation
• Aluminum housings
