Title:
CALIBRATION METHOD FOR MAGNETIC ENCODER AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/145647
Kind Code:
A1
Abstract:
A calibration method for a magnetic encoder and a system, which relate to the technical field of motor control, the method comprising: driving a motor (30) by means of an electric adjusting board (20) to rotate step-wise by using a preset electric angle; acquiring encoder data of each step point; performing linearization calibration on the encoder data by using a linear interpolation method to obtain linearized data of a mechanical angle, which may improve the calibration efficiency and accuracy of the magnetic encoder.
