Linear Magnetic Resistance
Linear Magnetic Resistance
(OP)
Hello All! Got one that has me stumped. We are working on a linear (or very slow rotary <100 rpm) magnetic resistance unit that would be used in exercise equipment for the disabled population, wheelchair transfer exercises and such. We chose magnetic because of its smoothness, lack of oil leaks, and controllability. What we need is a relatively inexpensive way to have a variably resistant force that uses little or no electrical current. Toro company apparently bought out a company years ago that was working on something like this, but I have not been able to find out anything about it. If anyone could enlighten me on this subject, and perhaps magnetorheological fluid systems, I would greatly appreciate it. Thanks.

I am working with rare-earth magnets for medical devices, and may be helpful, but I would have to see drawings to get a more complete picture of what you're trying to do. There are ways to counter a magnetic field, though none ideal in that they can completely shut off the field.
