LP12- Power Supply- Need education

I have read a lot about different options to upgrade the analogue power supply.
A phono stage need to amplify micro signal would require very good power supply to ensure there is minimal noise interfere with the signal.
I read about Lingo and other power supply articles, however they never mentioned about the science behind it.
How could a power supply powering a motor will introduce noise to the cartridge especially belt drive?
How do you measure the noise when playing a record?
Or would  the power supply provide a more stable rotational speed, my speed measurement on the turntable shows very consistence rpm once it is playing?
I really do not understand why a Lingo power supply cost so much but cannot provide an improvement with a measurable results.
Could someone educate me.

That was my experience with SOTA as well. The Phoenix inspired 3 phase SOTA Eclipse motor is an add-on option for the Sapphire and Nova series of tables and standard on the Cosmos. I am not sure how the new SOTA stock motors fair when compared to the older generations. I always admired SOTA's build quality
