## 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_3">Yedamale 2003</a>) and this [working principle](https://www.electricaltechnology.org/2016/05/bldc-brushless-dc-motor-construction-working-principle.html).

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" >}}))
