Fast, compact and precise–these properties characterize the new linear motor modules (LMM) from Bosch Rexroth . The axes are available in sizes 140, 180 and 220 and feature a zero-backlash direct drive. They complement the existing linear motion technology portfolio as a ready-to-install solution offering excellent value for money. The linear modules are available in all sizes with iron-core linear motors. The sizes 180 and 220 are also available with an ironless motor.
This opens up a wide range of applications with standard strokes of up to 1,540 mm and forces of up to 2,400 N. At speeds of up to 5 m/s and with accelerations of up to 250 m/s2, the LMMs achieve repeatability of ± 1.0 µm. These performance figures allow very short cycle times – an important consideration for the production of electronic and optical components, semiconductors or in electromobility. Typical applications include high-precision pick-and-place tasks, handling electronic components or automated optical inspections.
Maximum efficiency in the smallest of spaces
The high efficiency of the new linear motor modules is partly due to the integrated screw-free direct drive which replaces mechanical power transmission. This significantly increases dynamics and mechanical efficiency and allows great repeatability. At the same time, the modular design of the ready-to-install LMM reduces the installation effort. The new linear motor modules also reduce maintenance costs, on the one hand due to the maintenance-free linear motor and on the other hand due to the high-quality, long-lasting ball rail systems with long relubrication intervals.
