Embodiments of the present invention provide a motor magnetic pole position identification method, system, device, and storage medium. The method includes: sequentially injecting multiple pulse currents with different electrical angles into the stator of the permanent magnet synchronous motor, and simultaneously obtaining the Describe the motion feedback amount of the rotor under different pulse currents, and use the electrical angle of the pulse current whose motion feedback amount is consistent with the theoretical value of motion as the rough magnetic pole position; inject the q-axis component into the stator of the permanent magnet synchronous motor to be zero The disturbance current, and the position closed-loop adjustment is performed with the given position as zero, and the electrical angle when the rotor reaches a balanced state is used as the magnetic pole identification position, and the initial position of the d-axis of the disturbance current is the rough magnetic pole position. In the embodiment of the present invention, by injecting a disturbance current with a q-axis component of zero and a d-axis initial position of a rough magnetic pole position into the stator of a permanent magnet synchronous motor, the precise magnetic pole position can be obtained under a small identification action.
Description
technical field [0001] Embodiments of the present invention relate to the field of motor control, and more specifically, relate to a method, system, device, and storage medium for identifying a magnetic pole position of a motor. Background technique [0002] With the improvement of processing efficiency and processing accuracy requirements of display panels, mobile phone manufacturing, light-emitting diodes, semiconductors and other industries, the traditional drive structure of servo plus transmission can no longer meet the demand.
