Tubular Motor Manufacturers introduces the relevant knowledge of servo motors and stepping motors:

1. Servo motors are widely used in various control systems. They can convert the input voltage signal into a mechanical output on the motor shaft and drag the controlled components to achieve the purpose of control. Servo motors are divided into DC and AC. The earliest servo motors are ordinary DC motors. When the control accuracy is not high, ordinary DC motors are used as servo motors. Structurally speaking, a DC servo motor is a low-power DC motor. Its excitation mostly uses armature control and magnetic field control, but armature control is usually used.

2. The stepper motor is mainly used in the field of CNC machine tool manufacturing. Since the stepper motor does not require A/D conversion and can directly convert the digital pulse signal into an angular displacement, it has always been regarded as the most ideal CNC machine tool actuator. In addition to the application on CNC machine tools, stepper motors can also be used in other machinery, such as as the motor in automatic feeders, as the motor of general floppy disk drives, and also in printers and plotters.
