The MDrive product line expands with NEMA size 17 linear actuators combining leading all-in-one integrated step motor and driver technology with linear motion to deliver long life, high accuracy and unsurpassedrepeatability, all in a compact package measuring 58x56x43mm. The actuators are available in two shaft styles: non-captive and external. With non-captive shafts, a screw extends through the actuator and movesaxially as the motor rotates. With external shafts, a rotating screw integral to the motor moves a screw-mounted nut axially, with a choice of general purpose or anti-backlash nuts. Precision rolled screws for linear actuators deliver maximum life and quiet operation, and come with a choice of 4 screw leads to meet a wide range of application demands. Screws are manufactured from premium grade stainless steel, are corrosion resistant and non-magnetic, and available with an optional Teflon coating. The actuators are available with integrated electronics.
