11: Servo motors

Apparently this instrument contain a lot of motors. To design and build new motor system from scratch is time consuming and expensive. Göran, who is a very clever person, based on the designs in other areas which can be advantageously used to this. Believe it or not, but part of the servo motors are of the same type used in radio controlled model airplanes!
