The Nanomotor®

The patented Nanomotor® is a piezo driven linear motor. It is a multifunctional basic part for many positioning and manipulation devices. It has a positioning stroke of up to more than a centimeter while operating with atomic resolution. The Nanomotor thus bridges eight orders of magnitude.
The Nanomotor consists of a cylindrical housing and a slider with a free axial hole inside. It combines high resolution in the sub-nanometer range with a large positioning stroke. The Nanomotor utilizes a piezo tube for fine positioning and a shock wave produced by the same piezo tube for coarse movements.
The small Nanomotor is half the size of a match stick. It can lift six times its own mass. Every point of its stroke can be reached with a speed of up to 1 mm/s. The Nanomotor also works in ultrahigh vacuum or even under water. It is driven by a PC card at a supply voltage of only ±15 volts.

Centimeter stroke at atomic resolution

The basis of Nanotechnology is micro- or nano positioning. Piezoelectric crystals achieve high resolution down to the atomic scale. The drawback of this technique is the limited stroke of only a few µm.
This drawback is overcome by the patented Nanomotor®: It has a positioning stroke of up to more than a centimeter while operating with atomic resolution. The Nanomotor thus bridges eight orders of magnitude.
The Nanomotor is a linear motor consisting of a cylindrical housing and a slider with a free axial hole inside. It combines high resolution in the sub – nanometer range with a large positioning stroke. The Nanomotor utilizes a piezo tube for fine positioning and a pulse wave produced by the same piezo tube for coarse movements.
The small Nanomotor is half the size of a match stick. It can lift six times its own mass. Every point of its stroke can be reached with a speed of up to 2 mm/s. The Nanomotor also works in ultrahigh vacuum or even under water or in liquid Helium. It is driven by a PC card at a supply voltage of only ± 15 volts. The Nanomotor is available in three different versions (see below).
In its free axial hole the Nanomotor can transport a tip, a hose, an electrode, a hypodermic needle, a glass fiber, or even a micro gripper.
The Nanomotor is controlled by our PC Card.
Other electronics to drive the Nanomotor without a PC is also available, please ask for actual information.
