J.W. Fan Dismantling.

Zoomup:

At about 4mins+ in J.W. advocates connecting the fan motor directly to the mains supply if needed. Surely this can not be correct. What is the big Volt dropper resistor for? I don't think that the motor is 240 Volt rated.


Comments please.

That device that J.W. refers to as a transistor is actually a Triac thyistor.
