2016 Bosch motor 6004 RA3 194-06

Are there any COTS 8 point shafts available? If not, what would you suggest we use? We don't have the machining capabilities to make one out of metal. My first thought was 3D printing, but testing would need to be done to see how much stress a 3D printed shaft/hub could take.

This interfaces with quite a number of GM seats. It's a long list so I'll try to dig that out. It is specifically used for the recliner function in the power seats. I may have a few of these star shafts laying around that I can send if I find enough....maybe cut into pieces. I'll also see if we can find some scrap at our Tier 1.

Regarding efficiency I too was a bit surprised but that's what comes out of our dyno measurments. Actually too much efficiency is a problem in seat and window applications in that you don't want movement as the car bounces about on rough roads. In this motor there's a worm and two stages of spur gears for ~179:1 gear reduction.

Does anyone have a CAD file for it?

CAD model for the motor can be found at link through AndyMark. I should point out that there was an error in the first posted model which is currently in the process of being updated. I'll let you know when it is updated.
