High Speed Direct-Drive Linear Modules

PI introduces two new affordable direct-drive linear modules that can be operated as high load stages or linear actuators. Both modules provide higher performance and accuracy compared to screw-drive or belt-drive actuators, or linear slides with improved cost-efficiency. The maintenance-free design and the much higher operating velocities improve throughput in production along with a significantly better ROI compared to conventional linear slides, actuators or stages.Get more news about linear drive,you can vist our website!

The new linear actuators are fully assembled and tested and provide high resolution with 0.1µm minimum incremental motion. The high-performance, cog-free 3-phase linear motors provide excellent dynamic performance, high speed up to 5m/sec and high acceleration up to 5g with short settling times. Integrated optical linear position sensors measure down to 1nm increments.

V-857, the larger of the two, can handle loads up to 1000N and is offered with travel ranges up to 1.2m.

Wear Free Motor Design for High Reliability
The robust and stiff industrial design with backlash-free, wear-free, and friction-free smooth 3-phase motors guarantees operation for a long lifetime.

Driven by PI’s EtherCat-based high-performance industrial controllers, the smooth, cogging-free motors excel in precision motion applications where high contouring accuracy and smooth velocity profiling are of the essence.

Ideal for OEM Precision Motion Applications
The V-855 and V-857 linear stage/actuators were designed with industrial performance and affordability in mind and are ideal for high performance OEM applications. When XY motion is required, stages can easily be combined to form 2-axis arrangements.

Application Fields
Electronic parts assembly: sensor, camera, and optics assembly. Noncontact optical inspection, X-ray inspection, and AOI (automated optical inspection). Sensor and ultrasonic tests. Semiconductor manufacturing: wafer processing and inspection. Laser processing and machining: precision laser welding. Highly dynamic applications in precision automation, where smooth scanning motion, minimum tracking errors, and short settling times are required.
