Automotive disk brake retrofit to hysteresis/eddy current type

[amorrison]

Anybody know of a supplier of electric –no actual pad contact- disk brakes that use eddy current/hysteresis principle for their action.
A retrofit for the existing automotive disk caliper would be nice.
Thanks.

Yes Froude Considine. They are about 6 ft diameter and roughly as powerful as normal disc brakes.



Cheers

For heavy truck hysteresis brakes see

These are way too heavy and too powerful for my purposes - maybe there is a smaller system used somewhere.

Another name might be "eddy current retarder" which would be good for rpm control of a shaft at 80-100% of maximum speed.

Google these words:

None of these will be a foundation brake, but they should take a lot of the pressure off of the foundation brakes.

We don't know what your purposes are, so we're guessing.

I guess you could fit the brake to your driveshaft.

Plan on an axle cooler if you use it much.

The braking system should actively control the individual output shaft speeds of a differential. Brake pads will wear out quickly if required to operate almost constantly. Power input to the differential 100-200hp. Output shaft speed to vary from 80% to 100% of max rpm.

How about a water brake as in a dyno?
Use a water-air heat exchanger to dump the heat, of course.

so you're looking for a slip-limiting device or a device to control the torque split between two wheels?

Torque control.
