Hello, I would like to repair this brushless 12V fridge compressor motor (Danfoss 2.5) but first of all understand how it functions.
Inside are 3 coils.
It has an electronic driving unit: 2coils (photo 3)pin1-pin3 and pin3-pin4 of them are driven by mosfets. Total number of mosfets=3:
(the third one is for the fan). There is no mosfet driving the coil between connectorpin 2 and 3 ("WT" on PCB).
I add a diagram (temptative).
