Considered that, Neil, but the armature is direct drive to the pulley and fan and neither was moving.
Dimly recovered memory said that swapping a pair of wires would reverse rotation, so tried that and, indeed, it does However the speed pot on the pendant still works the wrong way – anti-clockwise increases speed. Has anyone got the'words and music' to make it work the right way, please?

It would vibrate at about 50Hz so you might hear it without being able to see any obvious movement.
