Hi alkv,

Maybe someone can help you if you post some pictures of the circuit board and the burned parts.

How many wires does your motor have?

Before we can help you we need to know what type of motor it is.

Hi Alun,

The motor looks like it might have a tacho or some other kind of feedback attached to its end.

I'm thinking it might be something more complex than a normal phase/PWM controller it could be a PLL constant speed controller.

Thanks for ur reply. Ok first the motor have 3 wire that goes inside motor and 2 wire is the behind of the motor. Im nor sure on the type or more detail. I had attach more clear pic. About the card also, i had attach but good one. The burnt card already sent out to repair.
