Hi Guys,
We ended up having a discussion in our office about electric motors and where we can find some.
What are using them for are manipulating valves (4 Way Barksdale Style) for a hydraulic closing unit (oilfield).
We have a few requirments.
1. They must put out at least 750inlb of torque
2. Must be small enough to mount on the front on the valve and not stick out from it (think a 4"x4" square as the front of the valve)
3. Preferably it needs to be explosion proof (but not neccessary)
If you ned mroe information, I probally can dig it up.
Thanks

RE: Electric Motors
I would say that if the torque were actually a lot less, you will need a DC gear motor to do the job, but get the torque down a bit.
RE: Electric Motors
The other option we have is to run an Linear Actuator, similar to what we use now.
The time frame, fast...~0.5sec or less for 90Deg of motion.
RE: Electric Motors
Normal motors and gearboxes are designed for continuous duty, which this isn't. What about an automotive or motorcycle starter motor with a gear reduction on it?
RE: Electric Motors
Using a gearbox might be a problem, but Ill look into it.
If I have more questions, ill ask.
Thanks
RE: Electric Motors
If you can't use a gearbox or a worm & wheel then an electrical solution isn't going to fit in that space. How fast do you need to operate the vales, i.e. you need 750inlb at what rotational speed?

If we learn from our mistakes I'm getting a great education!
RE: Electric Motors
Only thing is, to get everything hooked up (1/4" stainless lines) takes 40+hrs for the mid range units.
I was hoping for a easy answer to this, but running gear boxes and such might be more expensive than running line
