What kind of motors do industrial robots use and how do you control them?

$\begingroup$ Welcome to Robotics Da Mango, but I'm afraid that questions which are as broad as this are off-topic because answers would need to be too long. As it says in How to Ask If you can imagine an entire book that answers your question, you’re asking too much. We prefer practical, answerable questions based on actual problems that you face, so please take a look at How to Ask, tour and the Robotics question checklist for advice on writing a good question. $\endgroup$– Ben ♦Apr 7, 2022 at 13:09

Most industrial robot have servo motors. This allows you to control velocity, torque and position of motors - the latter usually in some form of closed-loop control system.
I work for Stäubli. Our early robots were actually hydraulic, the UniMate. Next were the PUMA robots which had DC servo motors. The modern RX, TX, TX2, TS, and TS2 arms have 3-phase AC servo motors.
