Re: (ET) Lift motor ideas?



What are the specs on those Cadillac/Buick window motors? Does anyone know the current draw under normal load, inch-lbs of torque, bearings, any other ratings? Are they made for only intermittent use or can they go for long periods without over heating? I have another project that this size of motor might work on. Appreciative of any info.

I have one of the 2 wire lift motors, it was on a E15 I got about 10 yrs ago, works fine. It had a ground wire hooked to the motor frame. I do not need it if someone is interested let me know

Yes, they came from cadillacs (maybe buicks too, I'm not sure), but you have to open it up and add a ground wire so that it doesn't ground through the frame anymore.

You could rebuild it. My guess is the brushes have simply
gone bad, the other possibility is one of the armature
windings have shorted.

Since these are Buick window motors one can get a new
armature in a motor for nothing on Ebay. Brushes would be
good too. The Elec-trak needed a certain lift motor (I think
it's the driver's side) but since you have the frame you
could use a passenger side (common and always in fine shape)
and swap in the armature.

I have about 4 parts motors in the shed for just this kind
of thing.
