What type of motors do grinders typically use and why?

Can anyone explain what type of motors grinders typically use, and why? As far as i know, -they are simply AC motors -They almost always have a capacitor in line to assist in spin up -lower rotation speeds are preferred, because they generate less heat -lower rpm means slower grind this is why low speeds pair with large burrs what is the reasoning for....
