Torque is the work either into the fan to accelerate it, or from the fan when it stops. The work is pushing against the inertia.

Emergency stops exist on machines like this but they are highly impractical. If something bad happens and the whole thing still runs, there is no point in stopping it. Stops are also always slow, even with active braking.

I don’t understand the design of this thing, there’s no curvature in o the blades which imply a centrifugal design but the case and everything else isn’t shaped for that either. How does this work? Looks like it would just spin around and create a lot of noise / turbulent air lol.

@@moonprofilepiclol454 Care to elaborate a bit genius? I probably have more time researching and training the aerodynamics and effects of propellers than you'll have in 10 f'ing lifetimes, but sure - unleash your childish youtube zing. The blades AREN'T curved (fine, easier to build) but the blades appear to have nearly two perpendicular surfaces, one of which is in-line with the rotation, which would hint at more of a centrifugal design. With the lighting and camera angle, it's impossible to tell - hence my confusion. If it was a typical fan-type circulation pump, you'd expect a medium-coarse pitch fan blade. Again, feel free to clarify since you obviously know far more about this installation and its engineering specifications than I ever will.

I think the motor is just for demonstration purposes. Seems to small also for the nominal job. It's a Walker fan impeller. They were commisioned in 1934.

The motor is being driven by a VFD (variable frequency drive) and the carrier wave / pulses to "imitate" the wave form (goes from 1 to 50hz slowly for motor "soft start). These pulses cause ringing and harmonics in the motor windings / magnets and vibrate causing the shrill sound.
