Title:
MOTOR COMPENSATION METHOD AND DEVICE, DRIVER, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/135389
Kind Code:
A1
Abstract:
A motor compensation method and device, a driver, and a system. Said method comprises: controlling a motor to rotate by a preset angle value, the preset angle value being an angle value corresponding to multiple parts obtained by equally dividing 360° (S1100); acquiring an actual angle value of the rotation of the motor measured by an angle measuring instrument (S1200); determining an angle deviation value according to the preset angle value and the actual angle value (S1300); determining, according to the resolution of an encoder and the angle deviation value, a compensation value corresponding to the preset angle value of the rotation of the motor (S1400); and within every one revolution of the motor and the motor rotates by the preset angle value each time, using the compensation value to drive the motor to rotate (S1500).
