    Default Anyone know what this thing is?

    I have had this thing sitting around for over 5 years now, it came from at auction with a bunch of other stuff. It was a metal fabrication shop.

    It has 3 wires Brown, blue, green so most likely runs off AC voltage. I am not game to try and plug it in yet though.

    Anyone know what it is?

    Could be a linear actuator, the big round thing would be the motor and the other long thin shaft thingy would be a ram.
    Voltage would be 12 or 24 and possibly came off a hospital bed or similar.

    Hi Guys,

    I think you could be right Dean ! The only way to be sure would be to unscrew the top and have a look inside.

    I did initially think that it could be a bearing heater, looking at that wear pattern on the bottom, but can't think for the life of me why it should be on such a robust arm.

    I was thinking maybe electro magnet, but the magnets on drills that I have seen have been all sealed up, the round bit I can sorta push it in a bit and it will spring back out.

    Kryn I don't think it is a linear actuator. The long shaft looks to be actual solid bar stock. If I undid the cap screw it should just slide out I would think.

    If you have a multimeter you could try and measure its resistance, that would give you some Idea of the voltage/current it would use. Take a reading with the probes both ways round, it might have a diode in there and that will give you two different readings.

    You mentioning that the round bit at the bottom flexes, suggests that it could vibrate and be used to seat a bearing or something similar in a recess ! But the only way to find out would be to either take it apart or power it up.

    Electro magnet as part of some sheet metal handling equipment? Feeding a press or similar?

    So I plugged it in, nothing really interesting happened, just tripped the breaker. I will have to pull it apart to investigate further.

    Well if nothing else, you have a bit of bar stock to play with

    Well just had a chance to pull it apart, it is just a limit switch. That explains why the breaker tripped when it was pushed.1539487640444~2.jpg

    It is the length stop from a punch and shear. You plug the wire into a receptacle on the machine and it takes the place of the foot switch. Slide the steel in until it contacts the plunger and then the machine operates, the steel drops away once cut and the machine resets.
