• Model: HAKKO FR300 220V Motor Specification
  Issue: Magic smoke escaped.
  
  I am trying to find a specification for this motor.
  
  I also did a bit of reverse engineering for the motor circuit and it's attached below.
  
  Hakko has all the replacement parts except the motor

• The bridge rectifier (S1WB) on the endcap PCB would suggest that the motor is actually a DC type.

• This much is obvious, it's clearly a permanent magnet DC motor. It could potentially be 220V although I suspect it is lower. A lot of hair dryers use a tap in the heating element to power a low voltage motor through a diode, I don't know whether Hakko does the same. Odd that they don't carry a replacement motor.

• Isn't this what you want? https://www.hakko.co.uk/product/699-032678-motor-for-the-fr-300/
  
  The picture doesn't look right but it does say it's for illustrative purposes only.

• Yes, it's a DC motor and has its own circuitry apart from the heating element section.
  I've done a bit of reverse engineering and the schematic is attached.

• Have you tried contacting Hakko?
  
  I'd open it up, worst case you can probably rewind it.

• Most of the time when I've had brushed DC motors fail it was the brushes or commutator that burned up but it's certainly worth opening it to look.
