Hi back GregC, I missed this important point yearterday . . .I was not at my best yeaterday out of the Dentist chair from a bone scraping.
You show powering this 12vdc blower from a battery. What was your supply battery voltage under a blower pulled down load?
Discharged battery voltage under a light load will be 12.25 volts. Fully charged 12 vdc battery lightly loaded will maintain 12.62 volts.
Yep. Full to empty on lead-acid batteries is measured in hundredths a of volt, within a less than a one volt range.
True gasifier blower motor experience. The very first time I face-to face met BenP was at a sponsored BBQ-invite 2008? 2009? He was demonstrating his just developed pellet/charcoal Emergency Power System gasifier. The one that got put into Mechanic Illustrated.
He’s made the suction blower just that morning from a junk vehicle heater blower assembly. It would not battery suck hard enough. I dragged out jumper cables from my mini-van and another fellow and I from his Chrysler/Dodge rental car gave it 14.5 vdc running vehicle power. Hey! It worked. Barely.
Told BenP I could pull a couple of vehicle batteries and series them and give it 24 vdc and it would work for sure. Probably spin it’s guts out over-RPMing. If not the bronze sleeve bearing would soon overheat and seize.
He then shop invited me to be his wiring-up guy.
I learned from him. Him from me.
Give your blower some charger higher voltage and report the results please.
A good 12vdc inverter supply will have an adjustable output voltage.
