    Hello, first off, this is my first post here, so I apologise if in some way I misplaced this post.
    I wanted to ask, is there any way I could measure if certain motor is 12v or 24v, and possibly if its ac or dc. Complete noob here, maybe this questions are ridilucous. There is no labeling on the motor, and I have two of these want to repurpose them for a motion sim. I included a pic, a 1 litre bottle next to it for measure.
    Just for context, there motors are taken out from a 30 year old dental chair, if its any clue, the light bulb the chair used was regular H3 car headlight bulb (12v I guess?) but have no idea the rest of the chair what voltage used. Thanks IMG_20260327_102218.jpg IMG_20260327_102213.jpg

    How can I check? Put something metal on it and see if it sticks? Or should I try to open it? Thanks
