Is it economically viable to make ordinary industrial motors rotate at tens of thousands of revolutions per minute?

A regular motor? Once you modify it, it’s no longer a regular motor

For tens of thousands of revolutions per minute, air bearings or magnetic bearings are likely required, and the cost is quite high. For ordinary motors that charge based on weight, it’s unlikely that anyone would use them

I haven’t thought about it in detail; I’m just wondering whether increasing the speed of the motor could improve the performance of certain devices, thereby generating economic value.
