FAQ on servo motors: part 2
The servo motor is an older precise-positioning motor arrangement now facing some competition from the stepper motor. Part 1 of this article introduced the concept of servo motors along with servo amplifiers and servo controllers. This part continues that exploration. Q: What’s the history of servo motors? A: There were purely mechanical, closed-loop servo systems […]
FAQ on servo motors: part 1
The servo motor is an older precise-positioning motor arrangement now facing some competition from the stepper motor. When engineers need precise positioning of a motor’s shaft (rotor) angle and associated mechanical system, their first thought in many cases may be to use a stepper motor (aka “stepper”). That makes sense, as stepper motors have the […]
