I never own any Sansui turntable, even though I am a huge fan of their tube gears - awesome output transformers. I am not familiar with that model but I don't think the motor is all that interesting. And judging by the look of it, they might have outsourced it from Denon. As a turntable, I would rather choose their later day coreless motor models like XP-99 or XR-Q7. As you know I am a big fan of coreless motors - super smooth sound. The attraction for me is the tonearm as it is knife edge design a la early SME but the horizontal movement is an inverted bearing on sapphire disc. Very unique for its time. Anyway, the table seems well built and might be a good performer.
Almost all info on Sansui turntables can be found on this site:

I have read about Sansui's latter day designs in addressing the counter torque issue with direct-drive motor by adding another motor underneath running in reverse to cancel the vibration. Not the most elegant solution but at least they acknowledge the issue. I much prefer Steve Dobbins' simpler and more elegant solution by decoupling the stator coil from the bearing assembly. Judging by the look of theXR-Q7 motor, Sansui might have outsourced that from Sony as it just like the BSL (Brush/Slot-Less) motor from a PS-X40, PS-X70, and others, even down to the tapehead servo system. Those BSL motors have rather flimsy construction on the bearing well as it is mounted on plastic(!!) as my PS-X65 got damaged in transit due to bending plastic. Maybe Sansui improved on it. Anyway, those two models, XR-Q7 and XP-99, are the only Sansui turntables have any attraction to me. Unless I find a beater XR-929 so I can scavenge the arm. :-)
