Electric Motors
This type of DC motor uses brushes to transfer current to the rotor.
brushed DC motor
This gas is most commonly used in pneumatic systems.
compressed air
The force in a hydraulic system is transmitted using this fluid.
hydraulic oil
A motor drive that gradually increases voltage to reduce inrush current.
soft-start
These actuators are commonly used in car door locks.
solenoids
This type of electric motor is known for its high efficiency and lack of mechanical brushes.
brushless DC motor
Compared to hydraulic systems, pneumatic actuators are generally lighter but have this disadvantage when it comes to force output.
lower power/force output
This is one of the biggest drawbacks of hydraulic systems, often requiring regular maintenance and leak prevention.
fluid leakage
This type of motor control device varies the frequency of AC power to adjust motor speed efficiently.
Variable Frequency Drive (VFD)
While hydraulic actuators offer greater force, electric actuators are often chosen in automation due to their advantages in these two areas.
precision and ease of control
This type of AC motor maintains a constant speed and is used in precise applications.
synchronous motor
What is the primary advantage of pneumatic actuators over hydraulic ones?
speed and lower weight
This law states that pressure applied to a confined fluid is transmitted equally in all directions.
Pascal’s Law
The most common method for controlling the speed of an AC motor.
Variable Frequency Drive (VFD)
This type of actuator is commonly used in robotic grippers.
pneumatic actuator
When comparing induction motors and synchronous motors, this one is more cost-effective and widely used in industrial applications under 25 HP.
induction motors
One reason pneumatic actuators are often preferred over electric motors in certain applications is their ability to function safely in these hazardous environments.
explosive or flammable environments
Hydraulic actuators provide significantly higher power density than electric actuators, making them ideal for these types of applications.
heavy-duty industrial applications
This type of motor control technique, commonly used with DC motors, allows precise speed and torque control by varying the pulse width of the input signal.
Pulse Width Modulation (PWM
This type of actuator is lightweight, requires minimal maintenance, and is often used in applications where speed is more important than force.
pneumatic actuator
This type of DC motor moves in discrete steps and is commonly used in CNC machines.
stepper motor
One major disadvantage of pneumatics compared to electric actuators.
inefficiency due to air compressibility
The main reason hydraulic actuators are preferred over pneumatics in heavy-duty applications.
What is higher force output
This electronic component is used in DC motor control to allow bidirectional movement.
H-bridge
In an industrial assembly line, this actuator type is best suited for high-force pressing operations.
