Magnetic Coupling through 0.8" 316 SS
Magnetic Coupling through 0.8" 316 SS
(OP)
Is it possible to have a magnetic coupling of a motor to a shaft through 0.800" 316SS? What would the torque limitation be?
We mfg. a 316SS vessel to process water, with an acme screw inside the chamber that performs a cleaning function. We are experiencing seal problems and the idea of magnetic coupling came up. Is this possible? Are there off the shelf solutions? Where can I find more info?
Thanks in advance for any help,
Joel

If, however, you could have a plastic housing inside or outside the tank, you could make a really good magnetic coupling.

Is coupling through stainless steel impractical? An external SS housing may be practical for us, but plastic would be a challenge.

I'm not aware of any thickness vs. torque curve, I would estimate you might get 1 ft-lb of torque. How much torque is involved now?

While I agree 0.8" is a huge distance, if the vessel is very large in diameter, it may be possible to transmit "some" torque, but probably not enough to be useful.
Much better to put a motor inside the vessel(air, hydraulic, or electrical) if you can possibly do it.
