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 is an important part of the servo system, speed and trajectory control is execution components; general rotor is a permanent magnet, drive controlled U / V / W three-phase electric electromagnetic field, the rotor under the magnetic field rotation.(12 145) Meanwhile, the encoder of the motor feeds back a signal to the driver, and the driver compares the feedback value with the target value to adjust the rotation angle of the rotor. (13)The accuracy of the servo motor depends on the accuracy of the encoder.
Servo "is" follow " control signal meaning, servo motor can achieve accurate control, can control as much to turn. And it also has a feedback device, which can achieve a closed loop, that is, the encoder can feedback whether the transfer to the quantity, so the servo motor accuracy is better. And the ordinary motor does not have this function, the ordinary motor is basically an electric turn, no power to stop.
Applications:
Medical equipment: Servo motors are used in medical equipment, such as in CT scanners and MRI machines, where precise control and positioning are required.
Toy cars and robots: Servo motors are also used in remote-controlled toy cars and robots, providing precise control of their movements.
Printing and paper handling: Servo motors are used in printing presses and paper handling equipment, where precise control of the movement of paper is required.
