Just curious why people buy these seemingly over-priced DC spindle motors like this:

https://www.automationtechnologiesin...or-and-driver/

They seem to be on a large portion of mini / benchtop mills and stores like Little Machine Shop seem to think that they offer "tremendous low end torque". They essentially imply that they offer the same low speed torque as motors with a gear reduction but without the gears.

Obviously, no gears are better than plastic gears if you get the same torque but is this really the case? LMS offers no info of what sort of torque they deliver which seems odd if it's such a selling point.

The 1.5hp variant sold by Automation technologies only offers 1.7ft lb of torque which suggests they offer no more torque than any other type of motor with equivalent power. So why would anyone buy one when they are at least 2 to 3 times more expensive than your average ebay 4 pole 1725rpm induction motor plus a VFD?
