Abstract

The invention provides a direct current compensation method for a stepping motor and a circuit. The method comprises the following steps: acquiring a driving signal of the stepping motor; performing spectral analysis on the driving signal to obtain a spectral analysis value so as to determine a current direct-current component amplitude in the spectral analysis value; and if the current direct current component amplitude is not the initial value, determining a target direct current compensation value based on the relationship between the current direct current component amplitude and the direct current component front amplitude so as to compensate the phase amplitude stored in a sine table based on the target direct current compensation value. According to the invention, the problem that the motor is jammed due to phase distortion at a commutation point when the motor moves at a low speed is solved.

Description

technical field [0001] The invention relates to the field of motor drive, in particular to a DC compensation method and circuit for a stepping motor. Background technique [0002] A stepper motor is an open-loop control motor that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by the load. The influence of changes, when the stepper driver receives a pulse signal, it will drive the stepper motor to rotate a fixed angle in the set direction, called "step angle", and its rotation is to run step by step at a fixed angle Yes, the angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; at the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, so as to...
