The precision Z-theta motion within one small actuator, providing a convenient pick, orient and place. A wide variety of linear rotary actuators are offered with either direct drive or gearbox equipped rotary units.
The vacuum-built-in shaft through the rotary motor is available for some models to prevent dust build-up in the unit. These z-theta actuators can easily be programmed to control force/torque, position, and velocity in all axes at the same time with feedback capability. SMAC’s unique, patented “Soft-Land” function enables the unit to gently land on a delicate component with a controlled force to avoid damage of both the component and the actuator.

The LDR, a precise, lower-cost linear rotary actuator, features a patented low shaft runout (<10 microns) HT motor with SMAC’s printed coil technology that eliminates motor cogging. The LDR is designed for pick-and-place electronic component assembly. Other applications include silicon wafer brushing, small-cap assembly, and small-screw assembly driver. A combination of improved design, the rotary motor’s laser manufacturing and printed coil technology, SMAC in-house manufactured encoders, and U.S. manufacturing contribute to the lower price.
