M-674 PILine® RodDrive piezo motor linear actuators represent a new level of integration between PILine® OEM piezo linear motors such as P-661 and guided micropositioning systems such as the M-661 linear stage series.
RodDrive piezo actuators replace classical motors in biotech applications such as syringe plunger drives, drives for HTS, etc as well as in non-magnetic applications such as MRI, SEM, or E-beam lithography.
RodDrives provide significantly faster response and higher speed than classical drive elements like rotary motor/leadscrew assemblies. Unlike classical electric linear motors, they are nonmagnetic and self locking at rest with no energy consumption and heat build up. M-674 actuators consist of a rod which is preloaded by ultrasoinic linear piezo motor from two sides. Depending on the way of integration, either the rod or the motor block is coupled to the moving platform. The basic features PILine® piezo linear motors offer compared to classical drives are
- Non-magnetic, vacuum-compatible
- Compact size
- High velocity
- Self-locking at rest, with no heat dissipation
Standard RodDrives are non-guided actuators and come without position encoders. Guiding and position feedback can be provided by the linear slide the RodDrive is attached to. Custom Systems for OEMs are available.
Flexibility and OEM Adaption
The maximum travel range of a RodDrive is limited by the length of the rod itself. The pushing/pulling force of the M-674 is 7 N. For OEM applications different piezomotors can be used, to achieve higher forces or reduce the size of the package.
Typical Applications
Medical design automation, system integration for micropositioning tasks, Automation, Handling, Micromanipulation, Biotechnology, Metrology
