Yesterdays test was done with these mods to the ECM.
Each phase seperated. Each phase hase 6 coils. These were seperated into 2 sets of 3 coils each.
These 3 coil sets were then perelelled. I ended up then with 3 phases modid this way. Then each phase group had its own fullwave bridge. Then the DC outputs of the bridges were perelelled.
First blade was the 55" TLG Boast buster 3 blade. Here are the #s.
5 mph 0 watts
10 mph 0 watts
15 mph 58.71 watts
20 mph 81.06 watts
25 mph 127.06 watts
30 mph 165.50 watts
I tested the TLG 2 blade Cyclone and got the same #s as the 3 blade Boast Buster.
Next A set of 48" Plastic "Jerry Blades"
5 mph 12.6 watts
10 mph 52 watts
15 mph 82.9 watts
20 mph 177.48 watts
25 mph 222.24 watts
30 mph 244.83 watts
Again these #s may be scewed do to the cab over wind of the truck. However It was a very calm day and both blade sets were tested the same way within 15 minutes of each other.
Todays test was done with this mod to the ECM. Stock star was seperated. Each phase hase 6 coils. The 6 coils stock are wired in sires. I left them wired sires but seperated the 3 phases. 6 wires coming out of the motor can. 2 for each stock phase.
Each phase was wired to its own full wave bridge then the bridge dc outputs were perelelled. This is twice the voltage output as the above scheem.
Again the #s for the TLG Boast Busters and this is also a 12 volt test.
Boast Busters.
5 mph 0 watts
12 mph 12.37 watts cutin
15 mph 24.88 watts
20 mph 62.80 watts
25 mph 95.18 watts
30 mph 103 watts
Since the Boast Busters are a 55" diameter blade I dicided to extend the "Jerry Blades" to 55" diameter also.
I figured the motor wiring configuration would cause more stall, operate at at lower rpm and it would be best to compair these 2 blades at the same diameter.
55" Jerry blade #s.
5 mph 0 watts
10 mph 25.4 watts
15 mph 38.17 watts
20 mph 103.55 watts
25 mph 117 watts
30 mph 128.92 watts
Looks like the top wiring scheem is the best I've found so far for the ECM for 12 volt use.
Next testing will be on the Wind Blue GM alternator with it in the stock star wiring mode with the TLGs VSs the Jerry rigged wiring mode with these Jerry blades.
Aint this fun?
Jerry
