  • When to Select an Electric or Pneumatic Rotary Actuator with Quarter Turn Valves
    Pneumatic and Electric Actuators each have advantages and disadvantages. The criteria in determining which is the best actuator includes the power source, on/off or modulating control valve function, media, hazard considerations, ambient temperature, environmental conditions, failure positon upon
  • What is the Difference between a Rotary and a Linear Actuator?
    Actuators can be classified into two types based on their motion. Two primary actuator types are rotary and linear. Rotary actuators will turn something a number of degrees in a circle â€" it might be a limited number or an infinite number. Linear actuators, in essence, move something along
  • What is a Rotary Electric Actuator and How Does it Operate on MultiTurn Valves
    The newest addition to Asahi/America 's Series 19 actuation product line is the MultiPack (R) rotary electric actuator. The Series 19 MultiPack (R) is specifically designed for multiturn and non-rising stem valves such as Asahi 's type-14 diaphragm and gate valves.
  • The History of the Rotary Solenoid
    solenoid switching proved to be reliable and long lasting, with an operating life of up to fifty million cycles. It also proved to be very fast, which led to another application: Camera shutters. The controlled high-speed actuators remain useful in imaging applications. Rotary solenoids became a standard
  • Actuator Tips
    Stepper motors are commonly used to translate motion from rotary to linear. Selecting the right combination of electrical and mechanical components is complicated by the various options for precision positioning systems. This brief will review key criteria for successful stepper linear actuator
  • Bistable Rotary Solenoids in Shutter Applications
    Geeplus offers small bistable rotary solenoids and actuators in several types, suited to actuation of small shutter mechanisms. These typically require rotation of a small 'flag ' to block or pass a light beam, or of a small mirror to deflect a light beam down another path. These miniature rotary
  • Stepper Linear Actuators Simplified
    What is a "linear actuator"? It is actually a simple stepper motor with a built-in leadscrew to directly convert rotary motion in form of discrete steps, into linear motion. Achieving linear motion internal to the motor eliminates the cost of designing a separate transmission mechanism
  • Smart Actuators - The Intelligent Choice
    Modern cars contain more than 130 motors to control everything from HVAC systems, coolant and refrigerant valves, headlights and seat adjustments to grille shutters, vehicle security and trunks. Most automotive actuators are comprised of an electric motor and gearbox assembly packaged in a housing
  • The 5 Best Industry Applications For Linear And Rotary Solenoids
    , which is then translated into linear or rotary motion. When the ferromagnetic actuator, or "plunger," slides "IN" and "OUT," this robotic motion is harnessed to either continuously hold a position or to operate as an ON-OFF pulse (latching). Through Johnson Electric's innovative engineering and design
  • Leadscrew Actuators: General Technical Overview
    Leadscrew Actuators produce linear movement from the rotation of a rotary motor. They are used in a variety of applications, including position adjustment of hospital beds and furniture, machine tool actuation, valve actuation, and others.
  • How Does an Electric Actuator Work?
    An electric actuator is a mechanical device used to convert electricity into kinetic energy in either a single linear or rotary motion. It automates damper or valve in order to increase process efficiency and complexity. Designs for electric actuators are based on the specific tasks they accomplish
  • How to Select a Stepper Linear Actuator
    Stepper linear actuators, or digital linear actuators, are devices that directly convert rotary motion into linear motion by using nut and leadscrew mechanisms. Unlike typical miniature motor technologies, linear motion is achieved in the motor itself, which eliminates designing separate
  • How Electric Rotary Valve Actuators Can Optimize Ethanol/Gasoline Blending at Truck Terminals
    room for problems or inconsistencies. Getting the needed control begins with accurate, consistent and reliable valve actuation.
  • Kimco Application Guide for Voice Coil Actuators (.pdf)
    Voice Coil (VC) Actuators are direct-drive, hysteresis-free devices used for providing highly accurate linear or rotary motion. By virtue of their high acceleration and the absence of commuta-. tion, voice coil actuators offer numerous advantages in such applications as medical, semiconductor
  • DC Linear Actuators vs DC Linear Motors
    Factory automation and robotic application engineers are often faced with the challenge of requiring fast, accurate and powerful linear actuation within a small allocated volume. The two most commonly available technologies are rotary DC motor driven actuators and linear DC motor actuators
  • Selecting the Proper Stepper Motor or Linear Actuator
    In order to select the proper motor several factors must be considered. Is linear or rotary motion required? Following is a list of some of the basic requirements to consider when choosing a motor. This will help determine if a linear actuator or rotary motor should be used.
