PI introduces V-551, V-552 motor stages & C-891 motion controller to PIMag series

January 18, 2017 – PI is expanding its PIMag series of high dynamics linear motor stages with 2 models and a motion controller. Stages are equipped with incremental and absolute-type linear encoders for direct position measurement and ironless 3-phase motors and single-phase voice-coil drives.

The V-551 models come equipped with an integrated absolute-measuring, encoder providing 2 nanometers resolution. Absolute encoders don’t require referencing and avoid accumulation of errors due to noise or cable issues. Precision crossed roller bearings with anti-creep cage assist help guiding accuracy (1µm straightness / flatness per 100mm).

With travel ranges of 5mm, 10mm, 20mm, and a maximum velocity of 250mm/s, the frictionless voice-coil drive is present in the V-52x series. An integrated optical linear encoder and precision crossed roller bearings with anti-creep cage assist provide positioning resolution and guiding accuracy. With low moving mass and no moving cables, the voice-coil direct linear drive results in high scanning frequencies to tens of Hz while not being subject to wear and tear. The stages can also be stacked to make XY systems.

PI’s compact C-891 motion controller is designed for sine-commuted 3-phase linear and rotary motors, is equipped with automatic detection of the motor phase. It can run on A/B digital or analog (sin/cos) encoder signals and also incorporates BiSS interface support for absolute-measuring encoders.
