The invention relates to a flux linkage estimation device, in particular to a flux linkage estimation device of a single chip microcomputer. The flux linkage estimation device of the single chip microcomputer aims at solving the problems that estimation on an existing stator flux linkage is limited on theoretical verification and instruction, and the flux linkage is difficult to really measure or display visually. The flux linkage estimation device of the single chip microcomputer comprises the single chip microcomputer, a current sensor, a voltage sensor, a power source, a displayer and a program and software module, wherein the program and software module comprises a current A/D conversion sub-module, a voltage A/D conversion sub-module, a flux linkage algorithm sub-module and a display sub-module. The specific process comprises the steps: 1, carrying out initialization, 2, collecting data of an input current sensor and an input voltage sensor, 3, carrying out 3/2 conversion of the voltage value and 3/2 conversion of the current value, 4, computing the equation that phi s= (us-Rsis)dt to obtain values phi s alpha and phi s beta of a stator flux linkage, 5, carrying out computing to obtain values phi s alpha and phi s beta of a rotor flux linkage, 6,7,8, outputting and displaying all the values, 9, judging whether outputting is finished or not, if not, carrying out the step 2, and if yes, ending. The device is suitable for flux linkage estimation.
