I've been playing around with the 5 linear actuators I picked up for nicks from a recent treasure hunt.
4 of them are 24V DC and one is a 220V AC
All the motors are working but one 24V actuator has an shredded motor to internal gear coupling so it's not going anywhere.
It looks like it would be possible to fix it with a bit of fiddling.
2 of the other 24V units are working fine in both directions but the 4th one is stuck in the "in" position and as its a sealed unit its going to be hard to fix.
The 220V unit was interesting - just a 3 pin plug/cord (no obvious switch) so after checking it wasn't short circuiting to ground I plugged it in and nothing happened.
Checking it over I noticed a small rubber nipple with small two holes in it. On opening up the connection box I found the nipple was connected via two lengths of silicone tubing to a pair of microswitches which were clearly the fwd and rev switches. To test the unit out I pushed two plastic pipettes into the holes in the rubber nipple and found that the unit would switching by applying a slight pressure to either pipette. This unit has 200 mm travel at 6.3 mm/s and a max lift capacity of 60kg.
Now what can I use them for?
