The Q-614 Miniature Rotation Stage is Tiny, Fast and Precise

Its turntable is only 14 mm in diameter and just 10 mm high, making the Q‑­614 rotation stage one of the smallest precision rotation stages available on the market.

Due to its extremely compact design, a rotation range of >360° and velocities of up to 70°/s, it is ideal for use in micromanipulation, biotechnology and automation applications. The Q-614 also comes in vacuum-compatible versions for 10^-9 hPa.

The Q-614 operates in open-loop control, typically achieving a minimal incremental motion of 100 µrad. 

The drive principle behind the miniature stage is based on a piezomotor inertia drive. This allows for the compact dimensions, the high resolution and the high velocity. Due to its ability to self-lock at rest, the piezomotor requires no power and produces no heat. It holds the position at a holding torque of 6 mNm.

The Q-614 is currently the smallest rotation stage within a series of stages that have turntables measuring 22 mm or 30 mm in diameter which allows them to be equipped with an additional position sensor for closed-loop operation.

The E-870 drive electronics makes open-loop control for the Q-614 possible and it is especially tuned to the requirements of the inertia drives. One device can serially control up to four channels, and is also available as an easy-to-integrate OEM version, which keeps investment costs low as an added benefit.
