PIMag® Magnetic Direct Drives

In particular, in terms of wear and dynamics, magnetic direct drives offer advantages compared to common spindle-based technologies. Since they use as few mechanical components as possible, this results in less friction and backlash and thus more precision.

System components like stator, actuator, or electronics are adapted individually by PI to the respective applications for the PIMag® series.

These bespoke solutions can be of benefit in many areas of automation and handling technology, for example, tip/tilt mirror, dosing, inspection and focusing applications, endoscopes or space telescopes.

Unfortunately there is no panacea for the ideal drive concept in positioning applications. Whether piezo-based or magnetic drive solutions are better suited, depends on the interplay of numerous parameters dictated by the concrete application.

For example, the required stiffness of the system, the travel required, as well as the power supply available, all need to be considered. Add to this the desired control behavior, the installation space available, as well as possible safety requirements, and, last but not least, the standards and the costs to be expected.
