What is the development trend of future servo motor control methods?

Servo motors are widely used in the field of automation control, such as in robotic arms and AGV vehicles, where there are varying numbers of servo systems. So, what are the future development trends of servos? Let's put it simply.

1. Communicationalization.
There are more and more servo motors of communication type. Compared to DC servo motors, AC servo motors generally adopt a brushless structure without a commutator, and there is little wear and maintenance. Meanwhile, the structure of AC servo motors is simpler, requires fewer materials, and has lower production costs compared to DC servo motors. Furthermore, the rotor inertia of AC servo motors is smaller and their dynamic response is better. Therefore, the alternating current of servo motors is almost inevitable.

2. Fully digitized.
By adopting a new high-speed microprocessor servo control unit to replace the servo control unit mainly composed of analog electronic devices, complete digitization can be achieved.

3. Highly integrated.
In previous servo systems, the motor, driver, and encoder were independent of each other and connected through cables. If designed in this way, the volume of the entire servo is too large, making it difficult to integrate into actual projects and more prone to problems, increasing the difficulty of after-sales maintenance. Therefore, it is best to integrate these parts together.
