Actuators are another important components of a mechatronics system. Actuators are usually electrical,mechanical,fluid power or pneumatic based.They transform electrical inputs into mechanical outputs such as force,angle and position.
Actuators can be classified into 3 general groups:
eg: AC & DC electrical motors, stepper motor, electromagnets.Actuators can be classified into 3 general groups:
- Electromagnetic actuators
- Fluid power actuator:
- Unconventional actuators:
Mechatronics system employ actuators or drives that are part of the physical process being monitored and controlled. Actuation is the result of a direct physical action on the process, such as removed of a work piece from a conveyor system or application of a force,it has a direct effect upon the process.
Actuators take low power signals transmitted from the computer and produce high power signals that are applied as input to the process. Electrical actuators converts electrical command signals into mechanical motions.
