I wanna know what will be the torque generated by this machine? and design calculations?and also specifications?

It depends on how hard the operator mashes the scraping head into whatever species and condition of fish.

Then a simple telephone call to the equipment manufacturer will provide the information far quicker than waiting around on CR4, where there hasn't been any history of discussions on fish descaling apart from the three generated by this thread's original poster.

If that comes to nothing, then there is always the option of the original poster carrying out measurement with a view to self-generating the design calculations and specifications, especially if the intent is to produce a competing piece of equipment.

<...I wanna know...> How rude.

It looks awfully not intrinsically safe. Nope, ask the fish guys if they prefer to be mechanized or remain rustic.

Some inventions are just stupid.

Why would need a fish descaler to be intrinsically safe? If you are concerned that your electric fish descaler has a chance of igniting your fish or scales, then you probably shouldn't be eating them.

Intrinsic Safety

Because the inventor is volatile.

Oh yeah may be IP xx water resistant perhaps.

It has a motor of some sort in it, so it cannot be <...intrinsically safe...> in the BS5345 sense.

Why one would want to use such equipment in a potentially explosive atmosphere remains a mystery to most readers...

Possibly his fish come out of flammable waters.......

Obviously you have an alternate use for this device as most know, filleting a fish is far cleaner, quicker and far less hassle. Maybe it is advisable if you want sensible answers is to state your case with more details.

That way no one will take the Phish.

from

(Revs. per minute per minute: what: an acceleration?)

Assuming 20W and that the blades are radially about 1cm long

I make that about 0.12 Nm

1cm is 10mm and that blade looked more like 80-100mm long (8-10cm). So that messes up your calc

Maybe around 0.49 Newton meter. (Just a quick assumed calc on 100mm blade).

I don't think the axial length of the blade is relevant to the calculation given the power and rotational speed; only the radial length is needed.

Of course if you were trying to work out the required torque from other given parameters the axial length would be very relevant.

I now agree with you as I have taken the axial length and not the radial distance. Rightly, my mistake.
