Abstract

The invention discloses a driving circuiting of a stepping motor. A current detection sensor is used for conducting zero crossing detection on the current of the stepping motor; then, the number of times the current value at a zero crossing point of the stepping point exceeds a preset value is counted in an accumulation mode through an accumulating counter; accordingly, a controller of the stepping motor can judge whether the stepping motor has rotation blocking or loses efficacy according to the number of times the current value at the zero crossing point of the stepping point exceeds the preset value and preset conditions. State inspection of the stepping motor can be realized without a position sensor which is used in the prior art and increases the cost, so that the problem of high cost in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a single-chip microcomputer, a driving circuit of a stepping motor, a driving chip and a driving method. Background technique [0002] In the prior art, for the drive control of the stepper motor, the position sensor is usually used to detect its position, so as to reflect whether it has abnormal conditions such as stalling or motor failure, but the position sensor used makes the entire drive circuit The design cost is greatly increased, which is not conducive to the development and application of the entire system. Contents of the invention [0003] In view of this, the present invention provides a single-chip microcomputer, a driving circuit of a stepping motor, a driving chip and a driving method to solve the problem of high cost in the prior art. [0004] In order to achieve the above purpose, the proposed scheme is as follows: [0005] A drive circuit for a steppin...
