Actuators Linear

Typically, a rotary driver for example, an electric motor, is mechanically connected to a lead screw so that the turning of the electric motor will make the lead screw rotate. A lead screw has a continuous helically wound thread that is machined on its circumference running along the length. Threaded onto the lead screw is a lead nut or ball nut which have corresponding helical threads. The nut is prevented from rotating with the lead screw interlocks with a non-rotating part of the actuators linear body. When the lead screw is rotated, the nut will be driven along the length of the threads.

The direction of motion of the nut will depend on the direction of rotation of the lead screw. By connecting linkages to the nut, the motion can be converted to usable linear displacement. Most current actuators linear are built either for high speed, high force, or a reasonable compromise between the two. When considering actuators linear for a particular application, the most important specifications are usually travel, speed, force, accuracy, and lifetime.

Uses of actuators linear

There are many types of motors that can be used in actuators linear systems. These include dc brush, dc brushless, stepper, or in some cases, even induction motors. It all depends on the application requirements and the loads the actuators linear are designed to move. For example, actuators linear using an integral horsepower AC induction motor driving a lead screw can be used to actuate a large valve in a refinery. In this particular case, accuracy and move resolution down to a thousandth is not needed, but high force and speed is.

For electromechanical actuators linear which are used in laboratory instrumentation robotics, optical and laser equipment, or X-Y tables, fine resolution into the micron region and high accuracy may require the use of a fractional horsepower stepper motor actuators linear with a fine pitch lead screw. There are very many variations in the electromechanical actuators linear system. It's very important to appreciate the design requirements and application constraints to know which one would be best.
