So, both of these motor styles behave like DC servos. The rotor position demanded for Command, or the sphere angle, is usually founded applying both a rotary encoder or maybe a sensorless strategy, that's described down below. Servo Motors: Servo motors give larger precision and precision than stepper motors, especially https://teamtinkernc.pointblog.net/the-science-of-magnetic-poles-inside-a-stepper-motor-90340448
