Servo motor, according to the requirements of the control command, the power is amplified, transformed and regulated, so that the torque, speed and position control of the output of the drive device is very flexible and convenient. Because of its "servo" performance, it is named as a servo motor. Its function is to convert the input voltage control signal into the angular displacement and angular velocity output on the axis drive control object. Servo motors are generally divided into two categories: DC servo motors and AC servo motors.
Ac servo motor The rotor inside the AC servo motor is a permanent magnet, and the U/V/W three-phase electricity controlled by the driver forms an electromagnetic field, and the rotor rotates under the action of this magnetic field, while the encoder of the motor comes with a feedback signal to the driver, and the driver adjusts the rotor rotation Angle according to the feedback value and the target value. When the AC servo motor has no control voltage, only the pulsating magnetic field generated by the excitation winding is in the stator, and the rotor is stationary. When there is a control voltage, a rotating magnetic field is generated in the stator, the rotor rotates in the direction of the rotating magnetic field, in the case of constant load, the speed of the motor changes with the size of the control voltage, when the phase of the control voltage is opposite, the servo motor will reverse. Advantages and disadvantages of AC servo motor Advantages: Good speed control characteristics, smooth control can be achieved in the entire speed zone, almost no oscillation, more than 90% high efficiency, less heat, high speed control, high precision position control (depending on the accuracy of the encoder), rated operation area, can achieve constant torque, low inertia, low noise, no brush wear, maintenance-free (suitable for dust-free, explosive environment) Disadvantages: The control is more complex, the driver parameters need to be adjusted on site to determine the PID parameters, and more connections are required.
Dc servo motor
The working principle of DC servo motor is basically the same as that of ordinary DC motor. Electromagnetic torque is generated by the action of armature air flow and air gap flux to make the servo motor rotate. The armature control method is usually used to change the speed by changing the voltage while keeping the excitation voltage unchanged. The smaller the voltage, the lower the speed. When the voltage is zero, stop rotating. Because when the voltage is zero, the current is also zero, so the motor will not produce electromagnetic torque, neither will there be rotation phenomenon.
Dc servo motor is widely used in numerical control system, but DC servo motor also has some disadvantages: its brush and commutator are easy to wear; The maximum speed limit of the motor, the application environment limit; The structure is complicated, the manufacture is difficult and the cost is high.
Advantages and disadvantages of DC servo motor
Advantages: precise speed control, torque speed characteristics are very hard, simple control principle, easy to use, cheap.
Disadvantages: brush commutation, speed limit, additional resistance, wear particles (not suitable for dust-free explosive environment)
