Actuators & Motors

In addition to classical precision actuators (leadscrew & ballscrew designs) Warsash Scientific also provide a number of advanced piezo motor actuators.

Ultrasonic PILine® ceramic motors are also referred to as resonant motors, and NEXACT®/ NEXLINE® PiezoWalk® motors are also referred to as piezo step motors (not related to inertial motors). Both can, in principle, attain unlimited travel, yet they are very different in their design, specifications and performance. These long-travel devices are different in nature to the classical (shorter-travel) piezo stack, bender and flexure actuators.

PILine resonant motors are characterised by a simple design and high speed to 800mm/s.

NEXLINE & NEXACT stepping piezo motor actuators are more complex and can achieve much higher resolution, forces and dynamic performance (analogue mode).

A great advantage of piezo motors is their intrinsic steady-state auto-locking capability. It does away with servo dither and the accompanying heat generation, an undesirable feature of electromagnetic linear motors. Stepping and resonant (continuous) piezo motors are in principle nonmagnetic and vacuum-compatible, a requirement for many applications in the semiconductor optics and medical industry.

  • Ultrasonic Linear Motors: High Speed, Resolution to 50nm

Nanometrology / Position Sensors

Nanometrology / Position Sensors

These capacitive sensors enable direct measurement of the moving platform and are especially well-suited for multi-axis measurements in parallel metrology configurations.
Technology From: PI (Physik Instrumente)

Nanometrology/Position Sensors

These capacitive (capacitance) sensors are the metrology system of choice for the most demanding nanopositioning applications. They are absolute-measuring, high-dynamics devices. Capacitive sensors/control electronics use a high-frequency AC excitation signal for enhanced bandwidth and drift-free measurement stability (subnanometre stability over several hours).

They enable direct measurement of the moving platform and are especially well-suited for multi-axis measurements in parallel metrology configurations. Parallel metrology means that the controller monitors all controlled degrees of freedom relative to "ground", a prerequisite for active trajectory control.

Capacitive sensors also offer the highest linearity (accuracy).
