Linear Cylinder Magnetic Motor

 

Find Suppliers by Category

Air cylinders are pneumatic linear actuators that are driven by a pressure differential in the cylinder's chambers. They may be single-acting (with a spring return) or double-acting.

  • Demystifying Linear Motor Integration
    and linear bearings. This may degrade the machine's mechanical design freedom. A second iron-core linear-motor configuration consists of a pair of stationary magnet tracks placed on either side of the moving coil. This patented construction negates the effects of magnetic attraction while delivering highest
  • Straighten up and go linear
    are key design targets. Two basic types of linear motors are iron core and ironless. Iron core motors provide higher forces for their size, but exhibit large force variations due to the magnetic attraction between the coil and magnet track. They also require heavy bearing systems to withstand
  • Linear actuators get a servo look
    . In the basic linear actuator, powerful rare-earth (neodymium) disk magnets encased within the thrust-rod setup alternate north and south magnetic fields that radiate out like spokes of a wheel. The stainless-steel (nonmagnetic) thrust-rod case protects against impact. (Mostly, this is protection against
  • Microwaves for cylinder sensing
    sensors offer a better alternative, says Seitz. They mount into the end face of linear actuators, where they continuously measure piston position and speed across the cylinder's entire stroke, he explains. The system relies on microwaves in the 1 to 24-GHz range, the same used in telecommunication
