I couldn't find such an adaptor, but you may be able to make your own. Find a section of small copper pipe with 1mm thick walls, with ID greater than 6MM and OD greater than 8MM. Cut a length to match the D-shaped section of shaft, and then squash it to a tight fit around the shaft. You'll probably need to cut it along the length to reduce some of the ...

It is most likely one of your capacitors. Some single-phase motors (which your fan has) have just a Start Capacitor and some have both a Start and Run capacitor. A motor circuit is simple. A couple switches, a couple capacitors, and the motor windings (inductors). If your fan still works after start-up, it's almost certainly not the windings. Windings ...

It may be that your start capacitor is dying out. If it works when you turn it on, then it can't be a contacts issue. It's possible the windings in your motor are wearing down or shorted, hence the extra current draw and the delay. Again you might have a ton of gunk in there.

Probably kitchen gunk on the switch contacts. It takes that long for the contacts to "sink" through the gunk. Replace the switch,

If you know the brand name, you can look up the technical specs even for discontinued models. Usually it will be a PDF file that includes a schematic. It does sound like an electrical problem. It could be something like a cracked solder joint that expands and connects after heating up that initial thirty seconds.
