Electric linear actuator design. 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. Gsa linear slide actuators the gsa linear slide actuator combines an electric rod actuator with guide rods mounting blocks and bearings.

Electric linear actuators are an alternative to pneumatic cylinders in several applications because of the flexibility they deliver in the design of production processes and production monitoring systems. Superb load holding power. A linear actuator uses one of a variety of mechanisms to produce motion in a straight line. Warner linear actuators consist of an electric motor combined with a high efficiency gear train and lead screw.

Video shows step by step. Engineering an electric linear actuator electric cylinder system in house is often the most cost and time efficient route to an automated motion solution. In conveying applications for example diverting and sorting functions are more frequently controlled using electric actuators. The actuator designers mainly use either of the two motors servo or stepper in their electric linear actuator applications.

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. This basic design converts the rotational motion in the dc motor to a linear motion. Roy schreffler design engineer skf. Detailed description of a home build balanced linear actuator for six degree of freedom 6dof motion platform for flight simulator.

The range of motion is called the stroke and can be measured in foot pounds of torque and inches of travel. A linear actuator is an actuator that creates motion in a straight line in contrast to the circular motion of a conventional electric motor. This direct conversion of electrical to mechanical energy results in effective economic linear movement. 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.

These motors have several specific advantages which makes them a popular choice in certain applications over the others. Units are completely self contained and require minimal installation hardware or wiring.
