The rotor field oriented control is the basis of high-performance AC speed regulation method-vector control. The key of this control is to calculate the rotor flux correctly. According to the theory of vector control and the operating principle of induction motor, several commonly used methods of indirect detection of rotor flux in asynchronous motor are carefully analyzed and discussed. Their own essence and its advantages and disadvantages
