An intersting idea for ballast.
Original poster: "D.Wightman by way of Terry Fritz <twftesla-at-qwest-dot-net>" <dwightman-at-mmcable-dot-com>
Some of you may think that I am totaly crazy, But just possibly some of you may
think that this is a brilliant idea!
I am a heat and air technician by trade. And just today this dawned on me. You
will find that all A/C motors have something called "LRA". That is locked rotor
amps.
Ok here is the idea, Let's say that you get a 3hp 208-230 vac single phase
electric motor.The LRA is 75 amps.
Now you hook up your pig in series with the input wiring to the electric motor.
Next you attach a second electric motor to the first motor . This will allow
you to vary the speed of the rotor in the first motor that is
wired in series with your piggie, or nst. Ahaa!!!! you now have a variable
ballast! If you look at the data tag on the electric motor that is being used
as your variable ballast you will also notice that there is another term called
"RLA" that is running load amps. On a 3 h/p motor at 230 vac it will be around
17 to 20 amps.
But the RLA is around 75 amps. Let's say that the motor is a 1075 rpm. That
means that if you can turn the rotor at 1075 rpm you will allow only 17 to 20
amps to your tranny. If you can slow down the rotor the amperage will get
higher, the slower the rotor turns the higher the amperage flow will be. If you
do not allow the rotor to turn at all the amperage through the motor to your
tranny will be the RLA of the motor. This is just Brilliant!!! Who needs a
welder? These electric motors are everywhere for real cheap.
Well what is everyone's thoughts?
