The embodiment of the invention provides a motor pole position identification method, system and equipment and a storage medium. The method includes the following steps: successively injecting a plurality of pulse currents with different electric angles into a stator of a permanent magnet synchronous motor, acquiring the motion feedback amount of a rotor under different pulse currents, and takingthe electric angle of the pulse current with the motion feedback amount consistent with the motion theoretical value as a rough pole position; and injecting a disturbance current with the q-axis component being zero into the stator of the permanent magnet synchronous motor, adjusting the position in a closed-loop way based on a given position of zero, and taking the electric angle at which the rotor reaches a balance state as an identified pole position, wherein the d-axis initial position of the disturbance current is the rough pole position. In the embodiment of the invention, by injecting the disturbance current of which the q-axis component is zero and the d-axis initial position is the rough pole position into the stator of the permanent magnet synchronous motor, a precise pole position can be obtained through a micro 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.
