>There are two kinds of AC motor: asynchronous and synchronous. We will focus on the synchronous ones because they generally perform better and more efficiently.

fwiw Tesla disagrees. True the peak efficiency is better, but the average efficiency is worse.

Synchronous motors can be nice where you have predictable loads, well thought out maintenance schedules, and few surprises. Or worst case just can't deal with AC.

Almost nothing falls in that category.
