Torque calculation for magnetic brake
Torque calculation for magnetic brake
(OP)
Hello,
I have a problem regarding the correct selection of a magnetic brake to be fitted to the centre shaft of a rotating table. The table weight is 40kg. The distance from the turning axis (centre shaft) to the edge of the table is 470mm.
I am using a magnetic brake device to prevent the table from "wiping" round during manual rotation. The Brake is supplied by "HUCO" however, I need to know the max. torque generated to correctly select the brake. I would be grateful of anyone who can assist me in solving this selection problem.

There seems to be no brake currently in the model at all. How do you intend to install the Huco brake?

If this is the only thing holding the table in position when someone is working on the workpiece then this is not a safe arrangement as an interruption of electrical power would allow the whole thing to move unexpectedly.
For this application you need a fail-safe energize to release brake.

Anti-back drive device might help.

If you're still intent on using a direct handwheel and a brake, at least make it a spring- energized brake.
