    wiring a proximity switch with motor

    Thanks for the reply, I guess I'll have to ask around my company and see if anyone here has some experience with this sort of thing. Thanks for the suggestions, I'll try to keep future posts to the sharing of ideas rather than looking for a substitute engineer. Davido

    wiring a proximity switch with motor

    Just a side note, my other post that was referred to was made around 3 years ago, back when I was first starting in Mechanical Engineering. Davido

    wiring a proximity switch with motor

    I'm just starting my first ME job, been on the job 3 months now, so still trying to get the hang of things. They don't give you very much practical experience in college, at least at my college, so I'm still learning a lot. This is for a fatigue tester. My company doesn't want to spend the...

    wiring a proximity switch with motor

    I'm kind of following your suggestion, and it seems like it will work, but I'm not quite sure how everything is going to be laid out. Could you sketchup some kind of diagram I can follow with the description? I drew up a sketch of what I understand it to be, but I think I've interpreted...

    wiring a proximity switch with motor

    I forgot to include some of the specs for the proximity switch that might be useful when answering. I've included the specsheet as a pdf for download. Davidohttp://files.engineering.com/getfile.aspx?folder=8c61174b-8463-4b2f-88fd-1494be28d9cd&file=3RG4024_KA_KB00.pdf

    wiring a proximity switch with motor

    I'm trying to figure out how I can wire a motor with a proximity switch so that as the motor runs, when the proximity switch is tripped, the motor will shut off and won't start again until I flip a reset switch. The motor runs on 120 volts and draws a fairly large current. The proximity switch's...

    variable frequency mechanical oscillator

    Here's a link to something like what i'm looking for, except for an electronic version. http://www.rexresearch.com/teslamos/514169.gif I believe the frequency of operation can be varied by changing the weight that you can add on top of the shaft. This engine is steam powered. Any ideas on how...

    variable frequency mechanical oscillator

    I'm trying to figure out a way I can make a mechanical oscillator, (I guess an engine where the shaft only moves up and down), where I can change the frequency of motion by small increments. Doesn't need to be very big, pretty small actually. Any suggestions on the best way to go about doing...
