From Matt, back in the day...
Also the AMP draw on a Tesla switch and Battery may be quete a bit different in the case of motor.
The reason primarly is the BEMF on the motor. When you ground a motor to run it both poles will create BEMF. This energy has to be disapated before current will flow. Reducing your actual flow time, and amount of flow. Also reducing the amount of energy actually doing work.
Running on a tesla switch you are only using either pole to run the load and nothing is grounded. BEMF is still being produced. but on a smaller scale and I suspect only on one pole. The pole that is opposite the polarity your on.
So if you are running on the ground side of the battery the North pole attracted part of the motor is making BEMF. This is my Theory I am still building up for testing. A Unipole motor may solve BEMF all together.
I have seen limited amounts of this on my scope in one way tests.
When watching the OUTPUT side of the motor on tesla switch you'll see 2 occilations. One is clear and obviously an ON/OFF wave. The other rises then falls but has both positive and negative spikes indacating BEMF. Depending on what side of the motor I power and what polarity of current I use the wave changes.
Also running test for the long term I have seen My batterries do not maintain the charge.
I have 4 Walmart lawn and Tractors. Hook the motor up straight to the batteries (all 4) in parrallel the motor will run the batteries down in 56 hours. Thats from 13.00 volt to 12.00 volt.
If I run the tesla switch till the batteries are dead (and they do die) it takes about 432 hours.
Thats about 8 times longer of a run.
I've tested the motor and gots docs on it its about 65% efficient when running under 12 volt.
I figure if the Tesla Switch is allowing for 8 time more runtime then I am recollecting about 85 - 90 % percent of the energy, I'm passing through. I know batteries loose maybe 5% percent because they are lead acid. The rest is lost through BEMF in the motor. This is what I am attempting to solve NOW.
So back your question why 250ma one way and 500 the other. Well you have dramatically reduced the amount of BEMF in the way.
The reason it does not feel any more powerful is because of the same thing I do not beleive that Both poles in a conventional motor are doing a full amount of work. So the motor runs slower or less powerful."

So what happens when you run a Unipolar motor in the CORRECT direction on a Tesla Switch? https://www.youtube.com/watch?v=QQRUclDiruw
