servo motor (servo motor) is an engine that controls the operation of mechanical components in a servo system, which is a supplementary motor indirect transmission device. It can convert the voltage signal into torque and speed to drive the control object, and has the characteristics of small electromechanical time constant and high linearity. The main feature of the servo motor is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases uniformly with the increase of torque.
Servo motors are widely used in many fields, such as:
Industrial production: Commonly used in machine tools, printing equipment, packaging machinery, food processing equipment, etc., to provide high-precision and high-speed motion control, effectively improve production efficiency and product quality.
Robot technology: It is the core driving device of robot technology, which can provide very stable and accurate position control, so that the robot can complete complex actions and tasks.
Aerospace: Plays an important role in the navigation and control systems of aircraft, providing precise attitude control and stability.
Medical devices: Commonly used in devices such as surgical robots, scanners and X-ray machines to achieve accurate motion and image reconstruction.
Automotive industry: It is often used in engine control, steering system, braking system, seat adjustment and other components to achieve accurate and reliable control.
In addition, servo motors also play an important role in advanced manufacturing fields such as 3D metal printing technology, whose high accuracy and stability help improve printing speed and quality.
According to the working principle, the servo motor can be mainly divided into DC and AC servo motor two categories.

VIA0703D02F0000 SERVO MOTOR
There are significant differences between servo motors and stepper motors in several ways:
Control mode: The stepper motor controls the rotation Angle by controlling the number of pulses, and each pulse corresponds to a step Angle. The servo motor controls the rotation Angle by controlling the length of the pulse time.
Workflow: The workflow of the stepper motor generally requires two pulses, namely, the signal pulse and the direction pulse. The servo motor workflow is relatively simple, usually only a power connection switch, and then connected to the servo motor.
Low frequency characteristics: Stepper motor is prone to low frequency vibration at low speed. The servo motor runs very smoothly and does not vibrate even at low speeds.
Torque frequency characteristics: the output torque of the stepper motor decreases with the increase of the speed, and will drop sharply at a higher speed, so its maximum working speed is generally limited to 300~600r/min. The servo motor has a constant torque output characteristic, that is, the rated torque is output within its rated speed (generally 2000 or 3000 r/min), and the constant power output is above the rated speed.
Overload capacity: Stepper motors generally do not have overload capacity. The servo motor has a strong overload capacity.
In summary, there are significant differences between servo motors and stepper motors in terms of control mode, workflow, low frequency characteristics, moment frequency characteristics and overload capacity. These differences make them suitable for different application scenarios.
