Motor driving method
The invention belongs to the technical field of motor control, and particularly relates to a motor driving method, which comprises the following steps of: abstracting a vector of which the phase difference of a three-phase line is 120 degrees, converting the vector to a two-phase first coordinate system alpha-beta by using a trigonometric function, and overlapping the first coordinate system alpha-beta on a motor rotor; respectively controlling two phases of the first coordinate system alpha-beta by using a PID (Proportion Integration Differentiation) controller to form a current loop; enabling the motor rotor to rotate in the 0-degree direction and the 180-degree direction respectively until the motor rotor stops moving, marking rotation limiting positions in the two directions, and determining a middle position according to the two rotation limiting positions; the motor rotor moves according to the two rotation limiting positions and the middle position, the flashboard is directly driven to move through the motor, and the flashboard can be directly driven to operate according to preset requirements by reasonably designing parameters such as the number of poles and torque of the motor, so that a transmission chain of a speed reducer is omitted, the cost can be reduced, and noise and abrasion can be reduced.
本发明属于电机控制技术领域，具体涉及一种电机驱动的方法，将三相线相位差为120度的矢量进行抽象后，运用三角函数将其转换到两相的第一坐标系α‑β上，并将所述第一坐标系α‑β叠合在电机转子上；使用PID控制器分别控制所述第一坐标系α‑β的两相，形成电流环；使所述电机转子分别向0°和180°方向转动，直到所述电机转子停止运动后标记两个方向的旋转限位位置，根据两个所述旋转限位位置确定中间位置；所述电机转子按照两个所述旋转限位位置和中间位置运动，直接通过电机驱动闸板运动，通过合理设计电机的极数、力矩等参数，使其可直接驱动闸板按预定要求运转，从而省去减速机的传动链，可以降低成本，减小噪声及磨损问题。
