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.

    Thanks Mike. Now I  understand. Other motors from the same stable are rated at 110V to 240V, so will work over a range of supply Voltages, but your 1 V drop will not make much difference to the motor then. Does the big Volt drop resistor (109) run hot continually or just when the fan motor is working?
