hi guys, new here.
hopefully somebody can help me understand this.
i have an old single phase motor here, the control pcb is no longer functioning so i thought i would try to build a new one.
i have found different variations of control circuits with triac and diac combinations, but what has me a bit confused is that this older motor has 3 leads.
brown, black and blue.
the brown and black are connected to the mains and start run cap, but the blue lead was connected to a bridge rectifier.
what is the purpose of the DC signal here? im having a hard time finding any info.
i hope my question makes sense, thanks in advance.
