Actuator (Pneumatic Cylinder/Electric Motor)

Product Specifications

Technical details and manufacturing context for Actuator (Pneumatic Cylinder/Electric Motor)

Definition

An actuator is the power-generating component within an end-effector system that provides the necessary force and movement for gripping, lifting, or manipulating objects. Pneumatic cylinders use compressed air to create linear motion, while electric motors convert electrical energy into rotational or linear motion, enabling precise control of end-effector functions. This directory entry covers actuators used in machinery and equipment manufacturing, specifically as components of end-effector systems. The product type is a component, and the abstract level is part. The actuator is available in two main variants: pneumatic cylinders and electric motors. Pneumatic cylinders operate by introducing compressed air into a chamber to move a piston, creating linear force. Electric motors use electromagnetic induction to generate rotational torque, which can be converted to linear motion through mechanisms like lead screws or belts. Both types provide controlled motion to actuate gripper jaws, vacuum cup movements, or other end-effector mechanisms. The actuator is typically constructed from aluminum alloy, stainless steel, or engineering plastics. Key parameters include bore size (32–200 mm, per ISO 15552), stroke length (25–500 mm, per ISO 15552), output torque (10–1000 N·m), positioning accuracy (±0.05 mm), supply voltage (24 ±10% V DC), power consumption (50–500 W), operating temperature (-40–85 °C), ingress protection (IP54–IP65, per IEC 60529), body material (aluminum or SS304), weight (1.5–25 kg), and pneumatic port size (G1/8–G1/2, per ISO 228-1). These values are reference ranges and must be confirmed for the specific model and application. Standards listed are procurement references, not certifications. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

Electric motors use electromagnetic induction to generate rotational torque, which can be converted to linear motion through mechanisms like lead screws or belts. Both types provide controlled motion to actuate gripper jaws, vacuum cup movements, or other end-effector mechanisms.

Frequently Asked Questions

What is the difference between a pneumatic cylinder and an electric motor actuator?

A pneumatic cylinder uses compressed air to produce linear motion, while an electric motor converts electrical energy into rotational or linear motion. The choice depends on application requirements such as force, speed, control precision, and available power sources.

What are the typical operating pressure and bore size ranges?

The bore size range is 32–200 mm (per ISO 15552). These are reference values; the actual model must be selected based on required force and application.

Can the actuator be used in washdown environments?

The ingress protection rating is IP54–IP65 (per IEC 60529), which indicates some resistance to dust and water. For washdown applications, a higher rating may be needed; verify with the manufacturer.

What standards apply to this actuator?

Standards listed include ISO 15552 for bore and stroke, IEC 60529 for ingress protection, and ISO 228-1 for port size. These are reference standards for verification, not certifications.
