The invention relates to the field of linear motor control, and discloses a motor verification method and system for a linear motor system, and a storage medium, and the method comprises the following steps: injecting excitation current into a motor, carrying out the open-loop motion control of an excitation current, carrying out the first current excitation, and locking to an initial excitation electrical angle m; current excitation is carried out again according to the excitation electrical angle n to judge the relation between motor operation and the grating ruler feedback direction; current excitation continues, whether the polar distance of the motor is matched with the grating ruler feedback resolution parameter or not is judged according to the error of the given motor electric angle increment motion and the actual grating ruler feedback change angle amount, and verification is completed. According to the scheme, whether the electrical angle direction is the same as the feedback direction of the grating ruler or not and whether the polar distance of the linear motor is matched with the feedback resolution parameter of the grating ruler or not are judged, verification only needs to be carried out when a linear motor control system is built for the first time, and the dangers of motor galloping, stalling, damage and burning are effectively avoided.
