Quality of movement for linear motors on unmachined machine frames

The self-supporting design of the cross beam axis gives the LMS E considerably greater inherent rigidity whilst maintaining the customary high level of dynamics and precision and can be mounted directly onto unmachined machine frames. Thus, our new modular linear motor series gives access to application areas which were so far reserved for more elaborate, less precise and less dynamic drive technology due to economic reasons.

The increasing demands on precision and/or dynamics in mechanical engineering and furthermore drive technology, are increasing across all size ranges. At the same time prices are dictated by traditional drive technologies which have approached the end of their development. Especially in 2D applications with gantry configuration, industry had reached a point where only a major step forward in development could have provided a solution.

With the modular linear motor system of the LMS E series we make available the acceleration performance, speed and precision of linear motor technology for applications which so far had to stay at other technologies for cost reasons. This will revolutionize entire sectors in mechanical engineering, especially gantry systems and the design of Pick & Place applications with loads up to approx. 30 kg.

The LMS E series, which is available as Economy and High Precision classes, consists of individual linear motor axes which are operated at a max. bus voltage of 560 VDC (optional 800 VDC) for special applications and which can be combined to give a portal configuration. The mass-optimized cross beam axis can also be used as a single axis, both supported and self-supported. Same as for the surface-mountable, horizontal axis for movement ranges up to four meters, they enable speeds in excess of 5 m/s and acceleration greater than 100 m/s². As with all KML linear drive systems, the LMS E series offers a very high power force density due to the integral design, i.e. low mass at high force.

The modular design and diversity of variants allows the LMS E series to be adapted to specific customer requirements with an economic design of the required geometry using accessories such as cables, chains and control electronics as well as built-on vertical linear motor axes. This results in our excellent price/performance ratio. Robust and accurate linear encoder systems are also available for the LMS E series.

A special feature of the LMS E series is the inherent rigidity of the linear axes. Whereas most available linear motor systems need to be mounted on precisely machined surfaces of solid supports, the LMS E can be mounted on considerably less costly profile tube constructions as the standardized leveling elements permit safe, aligning and easy mounting on unmachined machine frames. Additional savings potential compared with traditional solutions is given by the generally lower space requirements of the LMS E.

In total, the LMS E series allows the precision, dynamics and maintenance-free operation of linear motor technology for moving medium loads at a cost level of conventional methods.
