  • What are the advantages of a linear direct motor?
    Compared to spindle axes, linear direct drives are very dynamic, fast and precise. The low wear and low maintenance is also very advantageous for many applications with a high number of cycles. Compared to pneumatic axes, linear direct drives are particularly convincing due to their improved energy efficiency and better controllability.
