Sure looks like a windshield wiper motor.

SWMBO' s power wheelchair lift crapped out the other day. New
motor is no longer available since the lift is ancient.
Manufacturer of the lift removed any OEM markings. It's a right-
angle gear motor, which I'll eventually have some photos and
dimensions for. This is the in-and-out motor for a Harmar AL-600
lift that fits in the back of a van. Near as I can remember it was
made about 2007 or so.?
There is no continuity in the motor, but? othinf seems burned. I
pulled it apart and fiddled with it, and got continuity back.
Hooked it back up to power trying to get a current draw reading
and it spun up and? rapped out again. No continuity again. Brushes
look good.?
I have a megger for testing? insulation, and an assortment of DVMs
and at least one analog voltmeter. Somewhere in the library are a
couple of older books on motor testing and repair, but haven't
found them yet. Any suggestions for resources? I looked at
Grainger & McMaster-Carr, also Amazon & Surplus Center.
They have similar gear motors but nothing that looks exactly?
right. Most are either way too light or way too heavy. This is a
12vdc motor, could draw as much as 20amps, but probably closer to
10, and could less. There is another motor on it with a different
gearbox. Looks to be about the same motor. May fiddle with that,
and get a current draw.
Found one of these motors for sale on the knoppix site for $600,
was $400 from Harmar at one time. Seems a bit fishy to me, and
can't afford it anyway.?
Gotta get ready to take SWMBO to get fitted for a new CPAP mask,
and for both of us to get new CPAP machines. Hope someone can
point me in a useful direction. Used to be a bunch of folks whe
rebuilt motors & alternators/generators around here. Called
one and they don't do DC motors at all, and don't think there's
anyone left who does.,
Any help will be appreciated!
