Advantages and disadvantages of AC servo motors
Advantages: good speed control characteristics, smooth control in the whole speed zone, almost no oscillation, more than 90% high efficiency, less heat, high-speed control, high-precision position control (depending on encoder accuracy), constant torque can be achieved in the rated operating area, low inertia, low noise, no brush wear, maintenance-free (suitable for dust-free, explosive environments).
Disadvantages: The control is more complicated, the driver parameters need to be adjusted on the spot, and the PID parameters need to be determined, and more connections are required.
Advantages and disadvantages of DC servo motors
Advantages: accurate speed control, torque speed characteristics are very hard, simple control principle, easy to use, cheap price.
Disadvantages: brush commutation, speed limit, additional resistance, production of wear particles (not suitable for dust-free and explosive environments).

Estun Servo Motor - Introduction to Servo Motor Inertia Knowledge
1. What is "inertia matching"?
1. According to Newton's second law: "The required moment T of the feed system = the transmission inertia of the system J×angular acceleration θ angle". The acceleration θ affects the dynamic characteristics of the system, the smaller θ, the more time from the controller to the completion of the system's execution.
