Attaching power cable to a electrical motor.

That would explain why the wire tagged Z2 went out the bottom of the junction box.
And as for a brake, they are usually spring set- and disengage when the motor is powered. So a typical brake motor does not trun freely when not powered. But if the brake was damaged, as the end of that fan certainly was, it may be loose from the shaft, in which case the motor may spin freely. A picture of the inside of that shroud will explain it all.
In the junction box you can see the cable coming out from the underside of the box this goes to the cylinder attached to the right hand side of the frame, this is the capacitor. The motor is lying on its side with the feet on the left, putting the capacitor on top off the motor. The two cores of the cable go to the correct terminals for the capacitor.

There is no mention of a brake in the diagram or the nameplate.

It is true that there is no mention of a brake on the name plate, but it is also true that there is an unexplained cable exiting and going to that part that looks like an end cover. And since the capacitor is below the j-box that cable must be for something else. AND, The cable enters that other section with an actual cord grip. Given that the j-box has a threaded opening for the power lead it must be something else connected to that cable. That might be a brake.

The end cover is over the terminals for the capacitor.

Ah yeah you're right. I thought the cable was going to the end shroud, which was removed and laying beside it. But you can the end shroud separate in the same picture, so that's something else, almost surely the capacitor.
