Embodiment Construction

[0042] The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0043] First, some terms involved in this application are explained.

[0044] Position sensing component: used to determine the rotational position of the stepping motor based on whether the sensing signal is received.

[0045] In one example, the position sensing component is a Hall sensing component, and the sensing signal is a magnetic signal; the Hall sensing component includes a magnetic signal sensing part and a magnetic component, and the magnetic signal sensing part is used for the effective sensing A magnetic signal emitted by the magnetic component is induced in the region.

[0046] Wherein, the effective sensing area refers to: the range of the position sensing component from the...

Abstract

The application relates to a stepping motor control method, device and storage medium, belonging to the field of stepping motor control technology, the method includes: when the stepping motor runs to the effective sensing area of ​​the position sensing component, obtain the The number of regional running steps in the effective sensing area of ​​the component; based on the number of regional running steps, determine the current running steps for the stepper motor to run to the target rotation angle; control the operation of the stepping motor based on the current running steps, so that the stepping motor Run to the target rotation angle; it can solve the problem of inaccurate determination of the position of the existing stepper motor; because the stepper motor operation is controlled by considering the number of steps of the stepper motor in the effective sensing area, the stepper motor can be improved. The position of the motor determines the accuracy of the results, thereby improving the control accuracy of the stepper motor.

Description

technical field [0001] The present application relates to a stepping motor control method, device and storage medium, belonging to the technical field of stepping motor control. Background technique [0002] Stepper motor is an open-loop control motor that converts electrical pulse signals into angular displacement or linear displacement. It is the main executive element in modern digital program control systems and is widely used. For example: used in hair dryers, fans and other electronic equipment. [0003] In order to determine the running position of the stepping motor, a position sensing component (such as a Hall sensing component) is usually installed on the stepping motor, and the position of the stepping motor is determined through the sensing signal received by the position sensing component. [0004] In a typical position determination method of a stepper motor, a Hall sensor is installed on the stepper motor, and a magnet is installed at a fixed position opposit...
