Automatic detection system for winding of two-phase stepping motor

Abstract

The utility model relates to the technical field of two-phase stepping motors, in particular to an automatic winding detection system of a two-phase stepping motor, which comprises an output shaft of the two-phase stepping motor, a winding detection device used for detecting a winding is arranged outside the output shaft, and the winding detection device comprises a detection assembly, an alarm assembly and a controller. The detection assembly comprises a detection disc, a detection abutting block, a displacement block and a displacement sensor, three sets of sliding displacement grooves are formed in the detection disc, the displacement block is slidably located in the sliding displacement grooves, the detection abutting block is of an arc-shaped structure with the concave inner wall and the convex outer wall, the detection abutting block is located in the detection disc, and the outer wall of the detection abutting block is connected with the end of the displacement block; the displacement sensor is located at the bottom of the displacement block in each sliding displacement groove; according to the winding automatic detection system, real-time monitoring and fault alarm of the state of the motor winding are realized in a mechanical and electronic combined mode, and the problems of short circuit, open circuit or insulation damage of the winding can be effectively detected.
