Abstract

The invention provides an angle measurement method, system and device of a motor and a computer readable storage medium. The angle measurement method of the motor comprises the steps that a digital signal used for calculating the measurement angle of a motor rotor relative to the position of a magnetic angle sensor is acquired; according to the digital signal, calculating a measurement angle ''of the motor rotor relative to the position of a magnetic angle sensor, and comparing the measurement angle with a reference value of the angle so as to judge whether the measurement angle needs to be calibrated or not; if yes, calibrating the measurement angle on the basis of adding a calibration factor; and if not, returning to the step of acquiring the digital signal for calculating the measurement angle of the motor rotor relative to the position of the magnetic angle sensor. The rotating angle of the rotating shaft of the motor can be accurately measured, and the operation of the motor is accurately controlled.

Description

technical field [0001] The invention belongs to the technical field of motor measurement, and relates to a measurement method and system, in particular to a motor angle measurement method, system, device and computer-readable storage medium. Background technique [0002] At present, the angle measurement sensor devices used in high-precision permanent magnet synchronous servo motors on the market include rotary potentiometers, photoelectric encoders and magnetic encoders. Due to their high cost, rotary potentiometers are generally used in aerospace and military industries. The large-scale popularization of the application has a restrictive effect. Due to the limitation of the size of the code disc and the processing technology of the photoelectric encoder, the higher the accuracy of the grating, the corresponding photoelectric encoder is also very expensive, and the industrial use accuracy is generally not high; the magnetic encoder method Because the technology adopted by e...
