Actuator

An actuator is a electronic device controlled by a motor that moves the head arm to where it needs to go. In the past the actuator within a hard disk drive was controlled by a stepper motor. However, today the actuator is commonly controlled by a servo motor.

Function Of Actuator

Here is a small, simple and inexpensive device you can build if you want to use the Aux Functions of a DCC decoder to move something. It may be a door, a coupler or whatever. This device will give you a small movement (4-6 mm). The actuator should be used for momentary movements, like releasing couplers or activating doors. Or you can use it with intermitent power for a windscreen wiper. The resistor can get hot when activated for a long period of time.
If you connect the actuator to the motor output of a decoder (orange and gray), you get a nice little servo.

ACTUATOR ELEMENT

The actuator element simulates axial extension and retraction or relative rotation between the ends of the element in three-dimensional space. It can replicate complex, computer-controlled motion over time in any direction.

What is an actuator STIM?

A STIM that contains one or more actuators would be called an actuator STIM. If the actuator is a solenoid or valve actuator, it would be called a solenoid STIM, or a valve STIM respectively.

How is an actuator STIM set?

To set an actuator, a 5-step process can be used:

  1. Convert a setting in SI units to a raw actuator setting using constants stored in TEDs .
  2. Select the channel (the actuator that the information will be sent to)
  3. Write the raw actuator setting.
  4. Trigger the actuator.
  5. Wait until the STIM indicates the action is complete.
