  • NASA's Eight Legged Creation

    By Dan Finkelstein, Allied Cleanrooms NASA is developing a new eight legged creation called the Spidernaut. As the name would imply, the Spidernaut does in fact have eight legs. NASA has been looking for an easy means of working on vehicles, satellites and telescopes in orbit, and the Spidernaut could be a great solution. The eight legs of the Spidernaut move through the use of linear actuators. This provides flexibility and ease of movement when paired with its modular feet, and there are a lot of options. The modular feet,...

  • Linear Actuators in Medicine and Beyond

    I've enjoyed good health for most of my life. I've never had extended illness or any chronic conditions, and for that I'm grateful. But I'm also grateful that if I did become ill, I'd have access to the most advanced health care technologies in the world (assuming I had insurance). I've had only one major encounter with that technology, and that was minor surgery on my jaw when I was in high school. I went through the whole process consultation with my doctor, a CT scan and finally the procedure...

  • Actuator Manufacturers: Not One-Trick Ponies

    If you're in the business of manufacturing something, there's a good chance that your company doesn't manufacture only one product. Of course there are exceptions, especially in the case of highly-specialized products or in the case of very small operations. But it's more likely, in general, that a given manufacturing company manufactures a plurality of products rather than just one product in large volumes. Companies that are in the linear actuator manufacturing business tend to have their hands in a few other kinds of manufacturing as well, most notably pneumatic...

Industry Information

Electromechanical Actuators

Electromechanical actuators are devices that provide mechanical force through the conversion of electrical power. Becoming increasingly popular for industrial applications, electromechanical actuators offer several advantages over traditional hydraulic and mechanical linear actuators such as; increased mechanical efficiency, compactness, ruggedness, high load capacity, a minimum number of parts and easy assembly.

Industries that utilize electromechanical actuators include: military, for armored ground vehicles and aircrafts; medical, for medical infusion systems, medical bed positioners, dental chairs and additional medical and dental equipment; aerospace, in order to open and close cargo doors, move flight surfaces, stabilize rotating devices and other movement control applications; and agriculture, for use in tractor engines, cultivators and additional farming machinery and applications. Electromechanical actuators may differ in terms of what materials they are constructed from; such as metals like aluminum, steel and zinc, as well as having plastic parts at times for noise reduction purposes; in terms of the power source, which could include DC, AC, stepper and servo motors; and in terms of screw types such as lead or ball screws. Additional benefits of electromechanical actuators include decreased energy consumption, long service lives and increased power density.

Electromechanical actuators have a fairly simple design: they consist of an electric motor, a screw, a nut and possibly gears. The electric motor, also referred to as the driver, is mechanically connected to a screw. Thus, when the motor rotates, the screw will also rotate. A nut is threaded onto the screw through matching helical threads onto a non-rotating part of the screw; as a result, the nut is prevented from rotating along with the screw. Instead of rotating, the nut will be driven along the threads of the screw in a linear movement in the corresponding direction to the screw’s rotational movement. As a result, it is through the nut’s movement that the electrical energy is converted into usable mechanical energy. In terms of electromechanical actuators that utilize gear sets, the general purpose is for use in smaller motors. Not only smaller, but weaker as well, these motors spin at a high rpm and must be geared down in order to provide the necessary torque required to spin the screw in applications in which the load would be too heavy for the motor to be able to handle without additional support. Typical gears that are used for this application include worm gears, which are industrial gears that have a curved and recessed throat, or planetary gears, which consist of three or more outer gears that revolve around one central gear.
