## Short Stroke Actuators {#short-stroke-actuators}

For short stroke and very high dynamic applications, mainly two types of actuators can be used:

-   [Voice Coil Actuators]({{< relref "voice_coil_actuators.md" >}})
-   [Piezoelectric Actuators]({{< relref "piezoelectric_actuators.md" >}})


## Long Stroke Actuators {#long-stroke-actuators}

-   Linear motors
-   Piezoelectric Walking Drive ([PI](https://www.physikinstrumente.com/en/expertise/technology/piezoelectric-drives/piezowalk-piezo-motors/))

Rotational drives can be combined with ball-screw mechanisms for long (infinite) axial motion:

-   Brush-less DC Motor. See (<a href="#citeproc_bib_item_2">Yedamale 2003</a>) and this [working principle](https://www.electricaltechnology.org/2016/05/bldc-brushless-dc-motor-construction-working-principle.html).
-   [Stepper Motor]({{< relref "stepper_motor.md" >}})


## How to choose the correct actuator for my application? {#how-to-choose-the-correct-actuator-for-my-application}

For vibration isolation:

-   In (<a href="#citeproc_bib_item_1">Ito and Schitter 2016</a>), the effect of the actuator stiffness on the attainable vibration isolation is studied ([Notes]({{< relref "ito16_compar_class_high_precis_actuat.md" >}}))
