Description

Technical Field

[0001] The utility model belongs to the technical field of stepper motors, and provides an axial series controllable motor which can improve the operating stability of client load equipment, reduce the labor intensity of production line assembly at the production end, and improve the production line assembly efficiency at the production end. Background Art

[0002] A stepper motor is a micro motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. Its characteristic is that it rotates a fixed angle when each electrical pulse is input, thereby achieving precise position control. For example, it is used in technical fields such as security monitoring and air conditioning blade swing that require angle control.

[0003] See attached Figure 1 The existing stepper motor generally comprises a housing (1), a winding assembly (2) and an output shaft assembly (3) located in the inner cavity of the housing (1), a cover plate (5) located at the top end of the housing (1), an output shaft (4) of the output shaft assembly (3) extending out of the cover plate (5), wherein an upper claw pole (6) located on the winding assembly (2) is connected to a gear plate (7), and the winding assembly (2) is electrically connected to a drive controller fixed on the outer wall of the housing (1) through a wire. The axial string of a motor of this type of structure is composed of the thickness of the winding assembly, the thickness of the upper claw pole, the thickness of the cover plate, the height of the output shaft and the height of the sleeve. Since the tension of the enameled wire of the winding assembly during winding will affect the thickness of the skeleton, and excessive tension will cause serious deformation of the skeleton, thereby affecting the axial string. Since the thickness of the winding assembly has a great influence on the tension of the enameled wire during winding, and the tension of the enameled wire is uncontrollable, the axial string is uncontrollable. The uncontrollable axial string makes it difficult to assemble the production line at the production end, and the operation stability of the client load equipment is poor. Utility Model Content

[0007] In order to improve the assembly and positioning properties, in the above solution, further, the shapes and sizes of the convex hull and the cutout match each other.

[0008] In order to improve the assembly performance and the rotation performance of the output shaft, in the above scheme, further, a shaft sleeve is provided between the output shaft of the output shaft assembly and the cover plate.
