Various types of wholesale motor medical, 1. Servo motor
Servo motor is widely used in various control systems, which can convert the input voltage signal into the mechanical output on the motor shaft and drag the controlled components to achieve the purpose of control.
Servo motor has DC and AC points, the earliest servo motor is a general DC motor, in the control of the accuracy is not high, just use the general DC motor to do servo motor.DC servo motor is a DC motor with low power in structure. Its excitation is controlled by armature and magnetic field, but it is usually controlled by armature.
2. Stepper motor
Stepper motor is mainly used in the manufacturing field of CNC machine tools. Because the stepper motor does not need A/D conversion and can directly convert the digital pulse signal into angular displacement, it has been considered as the most ideal actuator of CNC machine tools.
In addition to its use in CNC machine tools, stepper motors can also be used in other machines, such as motors for automatic feeders, motors for general purpose floppy disk drives, printers and plotters.
