Motion Control

A motion controller is used to generate set points(the desired output or motion profile) and close a position and/or velocity feedback loop. A drive or amplifier to transform the control signal from the motion controller into a higher power electrical current or voltage that is presented to the actuator. Newer “intelligent” drives can close the position and velocity loops internally, resulting in much more accurate control. An actuator such as a hydraulic pump, air cylinder, linear actuator, splinted Johnson Rod, or electric motor for output motion.

One or more feedback sensors such as optical encoders, resolvers or Hall effect devices to return the position and/or velocity of the actuator to the motion controller in order to close the position and/or velocity control loops.

Mechanical components to transform the motion of the actuator into the desired motion,Including: gears, shafting, ball screw, belts, linkages, and linear and rotational bearings.
