Linear Rotary Actuators - Programmable in Force/Torque, Speed and Position
Standard linear resolution on all SMAC actuators is 5µm with 1µm, and 0.1µm options available on most models. The rotary resolution varies between 2,000 to 28,000 counts for gearbox units and 20,000 counts for the direct drive. Higher rotary encoder resolution and alternative geared motors to increase torque/gear ratio are also available. Please contact us with any special requirements you may have.
SMAC provides a comprehensive selection of combined linear and rotary actuators with either direct drive or gearbox equipped rotary units. They can easily be programmed to control force/torque, position and velocity in all axes at the same time. The actuator has SMAC's unique "Soft-Land" function which enables the unit to gently land on a delicate component with a controlled force to avoid damage of both the component and the actuator. This makes them ideal for applications such as pick and place and assembly.
NOTE: SMAC requires that all units must be operated at less than 40% maximum duty cycle.
Options and Modifications:
Encoder resolutions
5µm standard. 1µm, 0.5µm and 0.1µm optional for most units. Consult factory for availability.
Shaft ends
Male, Female, Blank and Custom (check availability of custom option)
Return spring
Prevents the shaft from dropping during vertical operation when power is cut.
Vacuum through the shaft
For pick and place applications
Extended nose bushing
For tighter shaft run-out and higher side load onto the shaft.
Increase of maximum force and acceleration
48 volt coil and double coil options are available for some units with 24 volt single coil. Please consult factory for availability.
Increase of torque/gear ratio
Alternative geared motors are available for some units.
Rotary encoder resolution
Consult factory for higher resolution.
Increase of force accuracy and lifetime
Extra long life linear guide / Low friction linear guide
