Suggestion for linear actuators? Some desired specs

  • Very fast [coompletes forward motion in 10-20 ms
  • Just a pulse reaction needed - Can move forward with great speed
  • Backward thrust not needed; can be done manually
  • Power available: 12 V, 1 A or similar
  • Can be electrically triggered actuators
  • Small [About 1/4th of hand]

Suggestions are welcome on DIYs and products.

  • \$\begingroup\$ Can you add more specs? how much mass (additional to the actuator) is to be moved - alternately how much force is needed? how much power is available (V&A)? how often is that movement going to take place? should the back-stroke be just as fast as the forward action? Are answers to be confined to electrical actuators, or can they be only electrically triggered? \$\endgroup\$ – loonquawl Apr 22 '18 at 19:07

    \$\begingroup\$ I would guess with the speed requirement you are limited to voice coil linear actuators: moticont.com/voice-coil-motor.htm \$\endgroup\$ – Jack Creasey Apr 22 '18 at 19:12

    \$\begingroup\$ @bukwyrm I have added most of the specs asked! \$\endgroup\$ – Osama Arshad Dar Apr 22 '18 at 19:20

  • \$\begingroup\$ Basic physics begs the questions; what is F=ma and E= 1/2 mv2= VI*t. ? In your specs!! \$\endgroup\$ – Sunnyskyguy EE75 Apr 22 '18 at 23:13

look into CO2 capsules, and the electric valves from softair-pistols (because they are geared towards the pressures encountered with those capsules, and they run on electrics with 9-14V) plus a small pneumatic cylinder (if you go with full pressure, those will act faster than you specced, but if you use the internals from a softair, the input is adjustable)
