Problems solved by technology

Although the subdivision control technology is the main control method that can effectively reduce the vibration and noise of the stepper motor during operation, the biggest disadvantage is that it needs to be solved by adding a subdivision drive circuit, which increases its hardware overhead cost.

Abstract

The invention discloses a precision-location stepping motor for a micro-stepping instrument, which comprises a shell upper cover (1), a shell lower cover (2), a permanent magnet rotor (3), a primary transmission gear set driven wheel (5), a secondary transmission gear set driving wheel (6), a primary transmission gear set driven wheel rotary shaft (7), a secondary transmission gear set driven wheel (8), a three-level transmission gear set driving wheel (9), a three-level transmission gear set driven wheel (11), a pointer drive shaft (12), an excitation winding coil XA (13), an excitation winding coil XB (14), a coil pin A (15), a coil pin B (16), a coil pin C (17), coil pin D (18), a stator iron core body (19) and the like. The reduction ratio of a three-level reduction gear system is 720:1, and the minimum location resolution is 0.0833 degrees; and the invention realizes micro-stepping rotation on the aspect of structure, does not need an extra drive circuit when in use and is a stepping motor for the instrument ,which has precision location and can enable a point to smoothly move.

Description

technical field [0001] The invention relates to a stepping motor for precision positioning micro-step meters, which is mainly used for pointer driving and precise positioning of various automobile digital instruments and industrial control pointer instruments. Background technique [0002] The traditional mechanical electromagnetic pointer instrument uses an analog method for signal processing, and the moving magnetic coil method outputs the pointer signal. Due to the fragile damping parts such as hairsprings, there are disadvantages such as poor accuracy and high failure rate. Compared with the traditional electromagnetic instrument, the stepper motor instrument adopts a new pointer stepping drive method, which completely abandons the analog working principle of using electromagnetic torque to drive the pointer, and is a new type of digital instrument with microcomputer control. It integrates detection, judgment, information processing and control functions. It has self-tes...
