Servo technology itself is a reference to frequency conversion technology, servo controller is through frequency conversion mode to imitate the control mode of DC motor to achieve is, in simple terms, AC servo motor has frequency conversion link, andVariable frequency motorIs to change the power frequency to50HZ,60HZThe alternating current becomes direct current, and then through a series of adjustments, the frequency becomes an adjustable waveform class, because the frequency can be adjusted, so the express can be adjusted and controlled.

       Servo motor can carry out precise action, it can be said to be a specially made control motor, through the drive instructions can achieve fast stop, fast forward, speed conversion, etc., but the premise needs to have a more complex drive to match; whileVariable frequency motorThat is, a frequency converter is added to the ordinary motor, which is a device that realizes the speed regulation of the motor within a certain range by changing the power supply frequency.

       In the occasions of speed control and torque control, the requirements are not very high, generally use variable frequency motors, and there are also closed-loop position feedback signals in the upper part of the position control with frequency conversion, and the accuracy and response will not be very high. Now some frequency conversion also accept pulse sequence signal to control the speed, but it does not seem to be able to directly control the position.

       In some cases where there are strict requirements for position control, we generally use servo motors to achieve, and the response speed is much higherVariable frequency motorIf the accuracy and response of the speed are required, it is recommended to use a servo motor. Generally speaking, the power of the inverter motor can be several hundredKWIt can even be higher, but the servo motor can only reach dozensKW.
