The main way to achieve frequency conversion in AC variable frequency motors is by changing the frequency of the power supply.
AC variable frequency motors usually use AC power supply, and the frequency of the power supply can be adjusted as needed.
When the motor is started, the speed of the motor can be controlled by controlling the frequency of the power supply.
When the power frequency increases, the speed of the motor will also increase accordingly; When the power frequency decreases, the motor speed will also decrease accordingly.
This can achieve variable frequency control of the motor.
AC variable frequency motors can also achieve better control effects by adopting vector control technology.
Vector control technology can decompose the current of a motor into two components, namely the excitation component and the torque component. By controlling these two components separately, precise control of the motor can be achieved.
