Problems solved by technology
[0004] However, the high and low levels cannot truly reflect the stability of the Hall signal of the motor. Therefore, the detection method based on the high and low levels will make the detection of the Hall signal of the motor inaccurate and cannot guarantee the stability of the Hall signal of the motor.

The invention provides a method, device and equipment for detecting motor hall signals and a storage medium and relates to the technical field of motor drive. The method comprises the steps of sampling a signal in each cycle in motor hall signals according to preset sampling time to obtain voltage values of multiple sampling points in each cycle, wherein the preset sampling time is preset time ofone signal change edge; determining whether the signal change edge in each cycle in the motor hall signals is qualified or not according to the voltage values of the plurality of sampling points and apreset voltage range, wherein the preset voltage range is a preset voltage change range of the signal change edge; if the signal change edge in one cycle in the motor hall signals is not qualified, determining that the motor hall signals are not qualified; and if the signal change edges in continuous multiple cycles in the motor hall signals all are qualified, determining that the motor hall signals are qualified. Compared with the prior art, the method has the advantage that the accuracy of judging the stability of the hall signals is improved.
Description
technical field [0001] The present application relates to the technical field of motor drive, and in particular, to a detection method, device, equipment and storage medium of a Hall signal of a motor. Background technique [0002] As a common device in the field of drive control, the motor can usually be commutated according to the drive of the motor Hall signal. During the commutation process, if the Hall signal of the motor is unstable, it will affect the performance of the entire system, thereby reducing the service life of the motor and the reliability of the drive system, and restricting its application in high-precision and high-stability applications. [0003] In order to ensure the stability of the Hall signal of the motor, it is necessary to conduct a qualification test on the Hall signal of the motor to determine whether the Hall signal of the motor is qualified. At present, the tool for single-chip square wave detection can determine whether the Hall signal of t...
