ELECTRIC ACTUATORS

The combination of AUMA actuators and spindledriven cylinders is a completely encapsulated electro-mechanical drive unit, converting the rotary movement of the actuator into a linear movement.

1:  Electric SA multi-turn actuator AUMA SA multi-turn actuators provide sufficient force to operate spindle-driven cylinders. The actuators are available in many sizes and versions and can be tailored to the individual requirements of the application. Depending on the variant, a handwheel is available for emergency operation.

2: The control unit as an integral part of the actuator provides continuous travel measurement and torque monitoring.

3: The brake unit is deployed for fail safe actuator solutions without self-locking. In standard operation, the unit maintains the cylinder in the desired position. In case of power failure, the brake unit controls the closing speed.

4: Spring assembly Integral spring assembly protects the electric actuator with spindle-driven cylinder against axial impact loads.

6: The spindle arrangement converts the rotary movement generated by the actuator into the actual linear movement. The spindle arrangement is composed of spindle nut and piston.

7: The housing is guiding the piston while protecting it against external impacts.

8:  The piston rod is pulled or pushed by means of the spindle arrangement.

9: The task is to guide the piston and, at the same time, act as a sealing element and protection against dirt and aggressive substances

10:Swivel head -The active force is introduced to the part to be moved through the screwed in swivel head. The version can be individually adapted to the application.
