The difference between classification and DC servo motor and communication

DC servo motors are brush and brushless motors.

Brush low electrical cost, simple structure, starting torque, wide speed range, easy to control, the need to maintain, but easy to maintain (replace the brushes), electromagnetic interference, the requirements of the environment. So it can be used for cost-sensitive general industrial and civil applications.

Brushless motor, small size, light weight, large output, fast response, high speed, small inertia, smooth rotation, torque and stability. Control complex, easy to implement intelligent, flexible electronic commutation, it can be a square wave commutation or sinusoidal commutation. Motor maintenance, high efficiency, low operating temperature, electromagnetic radiation is very small, long life, can be used in various environments.

AC servo motor is a brushless motor is divided into synchronous and asynchronous motors, motion control now generally use synchronous motors, large power range it can do a lot of power. Large inertia, the maximum rotational speed is low, and decreases rapidly with increasing power. Therefore suitable for low speed applications running smoothly.
