Actuators

Devices that produce a change in the physical system by generating force, motion, heat, flow, etc

• DC motors

• Actuators

• Sensors

• Pneumatic systems

Type of motions that actuators could generate

• Swinging motion
• Circular motion
• Linear motion, Rotary motion, Oscillatory motion, Reciprocating motion
• Straight motion

Type of actuators that use compressed air as the driving force

• Electric actuators
• Pneumatic actuators
• Mechanical actuators
• Hydraulic actuators

Type of actuator that use hydraulic fluid to amplify the controller command signal

• Pneumatic actuator
• Hydraulic actuator
• Mechanical actuator
• Electric actuator

It has the advantage of generating extremely large force from a very compact actuator.

• Magnetic actuators

• Hydraulic actuators

• Gravitational actuators

• Nuclear actuators

Characteristics of Actuators

• Size and volume, speed, efficiency, maximum output

• Accuracy, Resolution, Span

• Sensitivity, Repeatability, linearity

• Range, Resolution, linearity, accuracy

It is the cheapest form of all actuators

• solenoid actuator
• pneumatic actuator
• linear actuator
• hydraulic actuator

What type of cylinder it is the one in the picture?

• Telescopic

• Simple Effect

• Double Effect

• Double Double (effect and piston)

are not typically used for applications requiring accurate motion between two well-defined endpoints.

• Disadvantages of Rotary Actuators

• Disadvantages of Pneumatic Actuators

• Disadvantages of Electric Actuators

• Disadvantages of Linear Actuators

Leakage can occur causing a loss in performance

• Disadvantages of hydraulic actuators

• Disadvantages of Rotary actuators

• Disadvantages of Linear actuators

• Disadvantages of Electro-mechanical actuators
