The elevator door motor frequency conversion control system comprises an elevator door motor and a car door, the elevator door motor comprises a control unit, a permanent magnet transmission motor and a transmission mechanism, the control unit comprises a processing module and an intelligent power module, and the intelligent power module is used for vectorizing voltage to generate a voltage pulse sequence; the voltage pulse sequence comprises three-phase symmetrical sine-wave voltage generation and an ideal magnetic flux circle generated by an alternating-current motor during power supply, the intelligent power module inputs different signals to the processing module, and the processing module drives an elevator door motor to adjust a switching mode according to the input signals; the actual magnetic flux generated by the intelligent power module approaches the magnetic flux of the ideal magnetic flux circle, and after the actual magnetic flux is compared with the magnetic flux of the ideal magnetic flux circle, the working state of the intelligent power module is determined so as to control opening and closing of the elevator door. The intelligent frequency conversion control and permanent magnet synchronous transmission technology is adopted, stable, safe, reliable and efficient operation of the system is achieved, and the problems that people are clamped and trapped by an existing elevator door are solved.
