A gate motor drive system was introduced based on field oriented control, a complete set of hardware and software system was constructed, and the "one control and two drive" designed architecture was used to achieve better synchronization and reduced space occupation. Aimed at the level incompatibility in the "control drive" application circuit, independent components were used, and a set of level conversion levels was designed, which realized the low delay and high efficiency of level conversion, reduced the complexity of circuit design,and reduced the use of components. The movement process of the motor was analyzed, the magnetic field and direction of the motor were accurately controlled, and the opening and closing of the gate were completed according to the movement curve of the gate. The over-current and over-voltage protection measures of hardware and software were designed to realize the function of electric holding brake after moving in place, reduce the mechanical holding brake mechanism and save the cost. The experimental results show that the motor torque of the system is more stable, the noise is less, the efficiency is higher, and it also has better high-speed dynamic response, which achieves the design effect.
