First off, this was an old Toro leaf blower, not mine, and I am replacing it with new for the owner.
It still works, but today slowed down, and when I turned it off and gave it sniff test, knew something was not right.
I opened it up. At least 50$ of brush life left.
Commutator had two sections slightly raised compared to other sections, and burnt looking. Tell tale smell of it being done.
I figure shorted windings in the motor.
I cleaned it and tried again and same issue.
I bypassed the two speed switch and still same issue.
I had most recently been running it Via router speed controller, slowed way down to limit noise, and dust, and thrown projectiles.
Seems it was unhappy with the Pulsed AC.
The motor has a 2004 date on it.
Blower was in Mexico.
Bearings have been making whirring noises on slowdown for a few years. Perhaps failure was not related to the PWM speed controller. I was not using it when it slowed down and smelled funny.
Anyway, I would not mind retrofitting a 12v or perhaps 24v dc motor into it even if I lose some velocity/power
.
The failed unit does not state an amperage, but the newest version by Toro that looks similar, says 7 amps, which would be ~ 800 watts.
Not sure of RPM though. Direct drive of impeller.
I'd love to keep the failed unit out of the landfill, and install a 12v or 24v DC motor for use off grid on battery power, and use a PWM motor speed controller to dial in power needed for specific task, meaning workshop dust, rather than leaves. short durations, 10 AWG cable with 45 amp Anderson powerpole connectors
Failed AC motor is about 3 inches Diameter, and 5 inches from bearing to bearing.
Output shaft is flat. 3/16" across flats and 5/16" across round. 1 5/16" long.
Can use larger diameter motor modifying housing to accommodate.
Anybody tried something similar?
I get that it might be more economical to just run an new 120vac leaf blower off an Inverter for off grid use.
But if I could get a highspeed 24v DC motor for less than a new Toro (~ 40$), and waste some time tinkering, I'd be happy.
I'd also be happy, if possible, to save money just replacing the AC motor rather than buying new to replace what I broke.
Really liked using the blower on the router speed controller for certain tasks, Shame it seemed to kill it.
