Abstract

A control method for calibrating step motor connected to a controller and a load device includes outputting a control signal from controller to step motor according to a target displacement and a reference parameter, driving the load device, generating the second reference parameter according to the actual displacement, the first reference parameter, and the difference between actual and target displacements, and updating the first reference parameter.

Description

technical field

[0001] The present invention provides a method and device for controlling a stepping motor, in particular a method for calibrating a stepping motor and related devices. Background technique

[0002] Because of its very simple control mechanism, stepping motors have been widely used in various control systems to control the speed, displacement, and direction of a loading device. Stepper motors do not contain brushes, which drive the rotation of the rotor through the constant switching of the magnetic field of the poles on the stator. Therefore, the difference between a stepper motor and a general motor is that when the step The stepper motor does not rotate periodically when it inputs the power supply, that is, the stepper motor is a motor-mechanical device controlled by a digital signal. Whenever a digital pulse signal is input, the stepper motor will rotate a fixed Angle, also known as stepping angle (stepping angle). Since the stepping motor can directly ...
