It's mostly to do with resonance really.!! With good Digital drives like AM882 that deal with resonances very well then you wouldn't notice a massive diffference but on older analog drives then motors run on the bench can sound like can of marbles compared to being on the machine. To the point some struggle to spin if just placed on surface rather than being clamped down.
