Thanks Brian.
In answer to your question about the 12volts.....it was just the way the job evolved. It started off being a very simple stand, with a tipping device (worm reducer)on the top to rotate an aluminium fixture plate at 90 degrees. The whole stand also had to rotate 180 degrees too...
Yeah, the situation is not ideal Lukin1977.
I would prefer to wait for the right motor and make sure the cabling can handle the amps, but my hands are a bit tied on this now. The pressure is on to get it all finished and delivered. We couldn't wait up to 10 weeks for the other motor delivery...
That sounds like a good idea. I will mention it tomorrow and, again, when the motor arrives on Monday.
I am in the process of re-designing the stand (to fit the new style of motor and to make the pillar rise and fall with the actuator), and I am going to make sure that the other motor could...
Once again, thanks for your insight and expertise on these matters.
The factory it is being installed in is very spacious and well ventilated. The English town it is in hardly ever sees any warmth or sunshine....(sigh!)...so environment shouldn't be a major problem. However, if they are...
Thanks once again for your help and advise on this matter, it is greatly appreciated.
I have tried to explain the situation to those involved in this job here, and the consensus (at the moment) seems to be that we'd better not risk buying another motor that may not be up to scratch for...
Many thanks for your patience on this Waross.
I can appreciate it must be frustrating for you when I don't know anything about amps, or I2R, or how this has been effecting the torque issue.
Well, it looks like I am up the creek without a paddle on this one. I really don't know what to do...
What happens in-between the 4Nm and 40Nm? That sounds rather a large gap.
If I needed 10Nm to lift 120kg - and it can handle 40Nm without grinding to a halt, would I not just be running it at 25% more strain than it ought to run? Would this be a problem?
I am sorry, I am not quite...
This is another one, twice as much money, but 12volts and it seems to be 40 Nm instead of 25 Nm.

I'm sorry for being a bit slow on the uptake of this Waross.
As you may have guessed, I know next to nothing about motors, or torques, or amps and volts. My usual work is press tooling, jigs and fixtures to inspect components. It has been 20 years since I did any serious maths or science at...
Thanks for the extra insight Waross.
I was thinking of ordering the second motor, from R.S. Components, but now, I don't know any more.
The calculation for the needed torque is now established to be about 11 Nm. The motor allegedly outputs 25 Nm, more than double.
I do not know whether this...
Thanks Brian and Waross.
Brian, you make it sound so easy!
It looks like I have wandered around the houses to work things out backwards, but I had somehow come up with approximately the right answer.
Just out of curiosity, would you agree that the methodology I used is (kind of) right...
Looking through this again, am I right in the following?.....
I have used an online convertor to convert 35kg force per meter into Newton Meters.
35kg is allegedly 343 Newton Meters. To get the motor torque, would I then divide this by the 30:1 gearing on the worm box?
343 Newtons per meter...
Hello. I hope somebody will be able to help.
I have designed some equipment to assemble some large parts. It involves a stand and a fixture attached to it via a worm gear box.
The fixture and part needs to tip over at 90 degrees, from vertical to horizontal, and back.
After design and...
Yeah Mike, Im quite placid, but Im also a stickler for the rules ;).
I dont let it agitate me to the extent of leaving, but it just frustrates me how people arent striving to improve anything. Things take AGES to move along. If customers hadnt have stipulated we CNC parts back in the early...
What would people recommend as a general operating procedure, starting from when the job is given us to quote?
If thats too labourious, is there anywhere I can look up general 'chains' of command in such companies, or what recommended practices should ideally be?
Im thinking perhaps a...
Thanks for your quick replies!
Ctopher, Im not sure where youre based, maybe the United States or Canada?....but to be honest, over here in England, Engineering is "on its arse" generally, and finding another job as good as I have got (built myself up), is going to be difficult!.
I know what...
This is going to vary between the 'standards' of toolmaking companies out there, and even country to country, but I was wondering if anyone can advise me on the procedures to put in place specifically for toolmaking and fixture work, and general advice on how things should be run, or how you run...
Thanks for that, RCD.
I have had the impression that programs like Cadds5, Idea's, etc etc are quite old and clunky, stuck away in big companies which used to use the big computers that were necessary in the late 80's for 3d work lol. Perhaps Im misguided in that view lol.
Ive been looking...
One of our main customers is looking at the possibility of making all its outsourced work use the native I-deas format data, but in my knowledge of CAD and Cad Data, I dont see how this is possible. I wonder if you could clarify some things for me about I-dea's.
Appologies in advance if I sound...
Thanks Ajack1.
It seems you know the deal with the japanese data - really annoying isnt it! lol.
Somebody gave me a CD with Vero-Visi on it a few years ago, I think it was version 10 or 11. I spent most of my spare time after work coming home and looking at more CAD (lol), but after about a...
