QuadraPulser and DuoPulser
@UFO
I have worked all day to build a solid setup to test the Duopulser to get the data we need. I have had problems with ammeters being to large, one circuit didn't want to run today until I found the opto was plugged in backwards and something is wrong with the Tachometer. I think it is the tape on that small shaft. But although I did not get time to video the thing, I did get the amp readings.
I used 25.4 volts with my 4X asymmetric two brush motor and the frequency was locked at 30Hz and a max of 49.1 duty cycle on both lines.
RPM may not be correct but does reflect with some accuracy.
Test Amps RPM~
Series full linear .3amps but vary slow 2390RPM
Series single pulse @50% .25 2140
Single pulse one input .45 4830
Parallel full linear .8 5350
1 linear and 1 pulse @ 50% .78 5790
Parallel with two pulses @50% .4 4940
Note that the Duo pulse, last test, takes less amps than the third test and has higher RPM. I do not trust the RPM readings all that well. The fifth test has highest RPM but look at the cost. I wonder that by using the multi-pulse with higher volts it may turn out good. The addition of 12 more volts might push higher RPM than 5790 at half the cost.
I will add 12 more volts and see what that does soon.
Well, there are some preliminary numbers and I will redo them after I get a few things checked out with Tachometer and get a small ammeter.
