The new L-836 Stepper Motor Linear Slides from PI (Physik Instrumente) are a newly designed motorized linear translation stage family that combines high performance, small dimensions, and low cost of ownership. These compact micro-positioning translation stages are driven by a robust, direct-drive rotary stepper motor, available as in-line design and folded drive train design for reduced overall length.
Designed for multi-stacking, especially important in automation, the L-836 linear translation stages deliver high performance in a small footprint.
Due to the efficient, low-friction ball screw and robust, high performance, brushless stepper motor direct drive, the precision linear translation tables achieve relatively high velocity of 40 mm/sec and are well suited for automation applications in industry and research. The precision guiding system makes use of low-friction, high-performance cross roller bearings, capable of handling loads to 150 N (33 lb). The stage can handle push/pull loads of 75 N (16 lb).
When operated in micro-step mode, minimum incremental motion of 0.3 micrometers is possible. Even higher positioning precision, higher resolution and repeatability is available with optional digital linear encoders, removing backlash and reversal play due to the direct position measuring optical read head.
The L-836 stepper motor linear slides were designed with multi-axis motion applications in mind. The moving table platform can be removed, reducing the profile, and a Y stage can be directly bolted on to provide XY linear motion, without the need for additional mounting adapters. When space is limited, as it often is in motorized precision automation applications, the folded motor option reduces length providing a significant advantage.
For ultra-high-speed applications with extreme accelerations, PI offers industrial long travel linear motor slides such as the V-855 and V-857 compact linear module series with long travel ranges to 1,200 mm and high velocity to 5 m/sec.
The new L-836 family of stepper motor linear slides are designed for use in laser materials processing, test & inspection, electronics manufacturing, optical cable manufacturing, optics assembly, quantum photonics, silicon photonics, advanced manufacturing, and additive manufacturing.
