You may have noticed a space for a ball bearing in the previous photos of the stator. Note there is also space for a ball bearing centered in the resolver. The motor's rotor actually runs on ball bearings nestled within the rotor itself. A spline on the rotor transfers torque to the first driveshaft. Here is a shot of the rotor fitting on it's bearing space on the resolver side.
Here is a closup of the rotor, looking at the resolver side. Note the semicircular resolver rotor just behind the bearing.
An side view of the rotor. The resolver (between the bearing and main laminations) is only a few laminations thick.
The gearbox side of the rotor. The bearing is nestled in the laminations; also note the output spline.
The rotor OD is 5.825" (148mm) Also note how you can only see laminations. The magnets for this rotor are buried in a "v" form. Details about the reasons for this are in the papers I posted earlier. |
Hey e*clipse... I found a few of those drive units for sale again. Do you have any idea what the mileage was on the units that you have? The units I found have over 100k on um and I wanted to get an idea how well they wear over time?
Do you know what the max RPM is on the main rotor, I think I read somewhere that it is something like Ten Thousand RPM? Can you confirm....
From what I see in the pictures that resolver/rotor assembly would be a snap to make a new case for with the addition of an oil pump for cooling. Then use the first gear planatary set from a C4 or use an overdrive unit driven backwards so you get the reduction then direct. Then mount the whole thing to a transmission input.
My thoughts are that it would be easier for most DIYer's to install something that bolts to the existing transmission bell housing, rather than modify the entire rear suspension.
What are your thoughts on rewinding the stator for a lower voltage?
