See the attached.
The circuit is a Chinese treadmill board HV +B and driver side diagram.
The MOSFET used is what I think would be since the original one is burnt to a crisp and the number is not even slightly visible.
It happened due to it not being mount to the heatsink, the mounting bracket was missing. How ? not for now.
What I like to know is how the Mosfet is wired.
The motor is between source and ground. I presume the FET is N channel since the center pin has HV B+ Connected. Which would mean it is the Drain Terminal.
Now from what I have mainly seen, the Motor is in the Drain circuit, with the feedback resistor at the Source.
My question is will the MOSFET work wired like shown in the diagram or could it be an IGBT.
Since the motor is at the Source(emmiter), it is in the Switch Drive path, isn't it.
What I mean is the Motor Voltage will effect the Gate wouldn't it?
or Am I wrong?
