Abstract
A method for correcting an angle sensor is applied to a step motor including an angle sensor, where the angle sensor rotates with the step motor, and the method for correcting an angle sensor includes the following steps: rotating the step motor by a preset angle to a first position; reading a first voltage of the angle sensor when the angle sensor is rotated to the first position; determining whether the first voltage deviates from a preset voltage curve; if yes, recording a first offset of the first voltage relative to the preset voltage curve; and compensating for a sensing angle of the angle sensor according to the first offset. A device for correcting an angle sensor is further provided.
