You can test the motor by putting a 9v battery across the leads and if it runs then put a multi-meter across it to measure the resistance which should be between 3 – 13 ohms. If so, then the motor may not be the cause of the blown board.
The circuit board looks quite similar to the mini lathe/mill in our machines and others.
In case the motor is the problem you could compare dimensions with the our AMA25 750W motor on our website. It’s likely to be the same.
You’re welcome to give a call to discuss. Wifey has just arrived in Rhodes for a 2 week holiday so I have all the time in the world to assist if I possibly can!
