>And how do you see if they use it directly and not a DC motor?
Since that's a feature that knowledgeable customers will seek, it will be listed if it has one.

The product page for the Wahl 09243-2616 in OP's post >>2790310 explicitly says "WAHL STANDARD MOTOR: A durable, long-lasting electromagnetic motor that delivers superior power for smooth cutting" and "Motor/Drive: Electromagnetic Vibrating Motor"
The amazon listing for the Remington HC5855 in this post >>2790637 has a pic of the electromagnetic motor (pic related)

Basically, if it isn't advertised as having one, it doesn't.
Because that's an important feature that they want to highlight to customers who are looking for it.
