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 invention relates to a stepping motor control method and device and a storage medium, and belongs to the technical field of stepping motor control. The method comprises: obtaining the regional operation step number of a stepping motor in an effective induction region of a position induction module when the stepping motor operates to the effective induction region of the position induction module, determining the current operation step number of the stepping motor operating to the target rotation angle based on the area operation step number, and controlling a stepping motor to operate based on the operation step number so as to enable the stepping motor to operate to a target rotation angle. The problem that the position determination result of an existing stepping motor is inaccuratecan be solved. The stepping motor is controlled to operate by considering the operation step number of the stepping motor in the effective induction area, so that the accuracy of the position determination result of the stepping motor can be improved, and the control precision of the stepping motor is improved.

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...
