Re: slip clutch

That's a lot of heat and speed. If you can find something to run that fast, it will probably be water-cooled. Perhaps a company like Eaton has something that will work for you.

Re: Magnetic Particle Clutch

General industrial type Magnetic Particle Clutches range in torque from about 4 lb-in to 71 lb-in There are bigger units available, but less common. People tend to start using pneumatics or hydraulics for the higher torque industrial tensioning applications. There are smaller units too, but they ten...

Re: Failure due to vibration

Clutches fitted for outdoor equipment typically have a wound coil that is potted. It seals out contaminants. It keeps the coil from bouncing all over the place too. The electromagnetic clutches used on riding mowers are pretty rugged. Perhaps someone replaced the original clutch with some inferior t...

Re: Tooth Clutch used as a brake

You can use a tooth clutch as a brake. You would need to lock/bolt the output to a rigid frame. So, when you apply power to the clutch, it holds in place because the output is then locked to the rigid frame.

Over-Excitation

Just a quick post about over-excitation: For typical spring applied power-off holding brakes, there is a way to make a quicker disengagement (release) of the brake. Using your power supply, you can give a quick burst of power during the disengagement process. For small brakes, this could be for only...

Re: Can a clutch be engaged at speed or zero speed?

Can a clutch be engaged at speed or zero speed? I guess it depends on what kind of clutch you are talking about. What kind of clutch is of interest to you? Typical single surface clutches can be engaged at zero speed with no problem. The only clutches that "could" have a problem engaging at 0 rpm ar...

Re: Robotics

The brakes are getting thinner by the minute.

Also, there is a growing ability to make them smaller. 8mm OD is super tiny for a motor brake (low torque but high speed).
