Electric Linear Actuator Design

Linear actuators are used in machine tools and industrial machinery in computer peripherals such as disk drives and printers in valves and dampers and in many other places where linear motion is required.

Electric linear actuator design.

Units are completely self contained and require minimal installation hardware or wiring. Sometimes you are better off buying. This direct conversion of electrical to mechanical energy results in effective economic linear movement. The range of motion is called the stroke and can be measured in foot pounds of torque and inches of travel.

Roy schreffler design engineer skf. A high speed linear actuator would also be rated by the amount of time required to complete its linear travel such as inches per second. In conveying applications for example diverting and sorting functions are more frequently controlled using electric actuators. The rsx press model is an extreme force electric linear actuator that is more efficient reliable and precise than hydraulic cylinders used in pressing applications.

The most common design for an electric linear actuator is a dc motor with a transmission usually a worm gear connected to a screw nut assembly. Warner linear actuators consist of an electric motor combined with a high efficiency gear train and lead screw. Video shows step by step. A linear actuator uses one of a variety of mechanisms to produce motion in a straight line.

Superb load holding power. These motors have several specific advantages which makes them a popular choice in certain applications over the others. Gsa linear slide actuators the gsa linear slide actuator combines an electric rod actuator with guide rods mounting blocks and bearings. Ima linear servo actuators.

How electric linear actuators contribute to automate the functioning of doors. Whether the user is an electrical engineer or a mechanical engineer the electric linear actuator uses principles from both engineering disciplines says mr. This basic design converts the rotational motion in the dc motor to a linear motion. Engineering an electric linear actuator electric cylinder system in house is often the most cost and time efficient route to an automated motion solution.

A linear actuator is an actuator that creates motion in a straight line in contrast to the circular motion of a conventional electric motor. The actuator designers mainly use either of the two motors servo or stepper in their electric linear actuator applications.
