The HIWIN synchronous linear motor LMSA is a larger thrust type of linear drive motor product. It features high thrust density and low cogging force. The three-phase motor iron core is comprised of a primary side (forer) and secondary side (stator) permanents. The stator can be infinitely extended, so the stroke will be unrestricted.
