A traveling-screw linear actuator has a lead screw that passes entirely through the motor. In a traveling-screw linear actuator, the motor "crawls" up and down a lead screw that is restrained from spinning. The only spinning parts are inside the motor, and may not be visible from the outside. Some lead screws have multiple "starts".
Surplus Record is exclusively a publisher, and offers advertising services to Dealers, Auctioneers, Public Utility, and Manufacturers who want to sell their machinery, electrical, and power equipment through listings on the website as well as a monthly publication circulated to 55,000 manufacturers each month and 130,000 unique manufacturers over the course of a year.

The fly-ball actuator was introduced to R/C modelling in 1951 by Brayton Paul, [5] and consisted of an electric motor and a centrifugal governor connected to a free-running axis that could, with the motor running, pull a rudder control rod by varying degrees. Used with a keyed radio system, this allowed some control over the rudder position by ...
Switched reluctance linear motors (SRLMs) (also known as linear switched reluctance motors (LSRMs), variable reluctance linear motor or switched reluctance linear machines) are a type of electric machines called linear motors which work based on the principle of a varying magnetic reluctance for force generation. The system can be used in ...
A servomotor (or servo motor or simply servo) [1] is a rotary or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration in a mechanical system. [ 1 ] [ 2 ] It constitutes part of a servomechanism , and consists of a suitable motor coupled to a sensor for position feedback and a controller ...
Tubular linear motors are used in applications requiring linear actuators with performance that cannot be met by other forms of linear actuators such as pneumatic cylinders or lead screw linear actuators. Either the forcer (the part containing the coils) or the rod (the part containing the magnets) may be the moving part, depending on the ...
