Stepping motors and servo motors cannot be separated from stepping motor drivers. Everyone knows that AC servo motors need stepping motor drivers to operate. The rotating speed of ordinary AC motors is generally about 1400 rpm, why 1400? Because the general power supply is 220V and 50Hz, that is, 50 phase changes per second, while the general motor is 4 poles, that is, two phase changes and one turn, in addition, the ordinary AC motor is not synchronous, but AC asynchronous motor, so it is a little slower than the theoretical speed of 50/2*60 = 1500, so it is usually about 1400 revolutions. It can be seen that the rotating speed of the motor can be changed by changing the power supply frequency. Such a controller corresponding to a common motor is called a frequency converter. The control of servo motor is more complicated. It is necessary to change frequency, voltage and current to achieve comprehensive control of motor speed, torque and position. Servo driver is used for this purpose. The AC servo motor needs a driver to operate. The servo driver is only responsible for giving frequency and voltage, and the motor makes corresponding instructions. The servo controller is responsible for changing the frequency, voltage and direction. The AC servo motor needs to be driven to run. In addition, the servo controller has no logic control capability. If the servo motor needs to rotate slowly, then rotate fast, then stop somewhere, then reverse, etc, these signals are the responsibility of the upper controller of the servo controller, such as PLC and motion controller.
