Servo motor refers to the electric motor that drives the operation of mechanical elements in the servo system.
It is a controllable mechanical electromagnetic device for mechanical energy conversion and signal conversion in the precision motion control.
Servo motor should be designed to fit the characteristics of the servo system: fast, accurate and stable. So the servo motor design key points: light weight, large output, fast response, high speed, small inertia, smooth rotation, stable torque and so on.
The motor operates in an automatic manner and does not shock and lose steps when the load changes. By using an appropriate transformation algorithm, the thermal performance can be improved, with better motor speed range and response time, and possible for better electromagnetic isolation, and better torque response.
Servo motors can be either analog or digital.
Analog servo motors use analog control signals to control the position of the motor's shaft. These signals are typically generated by a microcontroller or other control electronics and are sent to the servo motor via a control cable. The servo motor then uses these signals to determine the position of the shaft and adjust its operation accordingly.
Digital servo motors, on the other hand, use digital control signals to control the position of the motor's shaft. These signals are typically generated by a microcontroller or other control electronics and are sent to the servo motor via a digital bus, such as a USB or Ethernet connection. The servo motor then uses these digital signals to determine the position of the shaft and adjust its operation accordingly.
