Hi; Been awhile since I posted. Hope everyone is well. I need help on a unusual project. I have a rather new motor - blower assembly out of a clothes dryer. I ...
It would help if you could provide a little more information. What brand of dryer did it come out of? Is it a 210 volt or 110 volt dryer? ... From: keith_hal...
1. Contact a local electric motor supplier/re-builder (see the yellow pages) and talk to them about the wiring. Otherwise try looking in the yellow pages of...
Greetings, If the motor is 220 volts, and you are running it on 120 volts, it will overheat because you will be "running on half the windings". It can also ...
... Most electric dryers that I've seen used 120V motors and 240V heating elements, and in old houses where fuses were used (or where there was a bad ...
Hey guys, Thanks for the great response. I managed the wiring okay thanks to your help. For future reference, it is 120 volt, pins 3 and 4 are the drive pins....

I was tinkering with a handheld stungun/stunner, trying to make it into a jacobs ladder. I can't get it work - I just get arcs, I was wondering if anyone here...
... Hi Justin, It can't be done unless you dramatically increase the pulse repetition rate and the average power level of the stun gun. You're forming sparks, ...
The stun gun is using a DC-AC inverter with probably square pulses and a low duty cycle. In order for the Jacob's ladder to work correctly the spark had to...
Thanks, that's very helpful. (I didn't realise how quickly the air becomes dielectric again). I narrowed the spark gap and raised the pulse rate a lot more, ...
Neon sign transformer is 120Hz pulses, actually, since each peak counts as a pulse. It is also much higher power, and a broader pulse. I seem to recall that...
You probably simply don't have enough current to heat enough air. Also, since it's a pulsed device, the air may be cooling down between pulses. Or, it might...
