Re: [MBZ] OT Conv top electric motor question
So, what is up with this thing and can it be made to work right? If there's nothing visibly wrong and the brushes are OK, then it's likely you have a shorted winding, which saps the torque considerably. Unless you can/will rewind the motor, either the armature (spinning) or the field (stationary), whatever's necessary, it's shot. There are motor rewinding shops, but likely it'd cost you more than your replacement would. DIY might work, but it's not an easy task for the novice. I've never done it. I am thinking about getting window lift motor of some sort and bodging up some kind of adapter -- those things have hellacious torque. They're just motors, usually with reduction gearboxes. If you can find something that will work and the motor's strong enough then go for it. -- Jim
[MBZ] OT Conv top electric motor question
The electric convertible top motor on my 76 Eldo quit working. A replacement is like $250 -- crazy. I got it spinning, but it has no torque and won't even turn the reduction gearbox that turns some flexible shafts that go to the top lift mechanisms on either side, and I can hold the shaft with pliers and it does not have much torque. So I don't know much about electric motors, but this thing looks pretty simple. It has a coil sitting below a small plate that fits around the armature about 30deg maybe. (I don't know what that part is called). 12V passes through this coil one way or the other to make it spin the right way for up/down. 12V is switched by a relay to the armature brushes. I cleaned everything and it spins fine when I put 12V to the motor power wire and the coil wire, just no torque. The reduction gear box spins OK -- I cleaned and regreased it all. The whole armature is about 4 inches long, an inch or a bit more diameter. The relay works OK. So, what is up with this thing and can it be made to work right? I am thinking about getting window lift motor of some sort and bodging up some kind of adapter -- those things have hellacious torque. Anyone? Bueller? Bueller? --R
