Abstract

A method for improving the acceleration and deceleration characteristics of step motor features that the torque of step motor is incremental or decremental in step mode, so quickly accelerating or decelerating.

Description

technical field [0001] The present invention relates to a method for improving the acceleration and deceleration characteristics, and in particular to a method for improving the acceleration and deceleration characteristics of a stepping motor Background technique [0002] With the continuous evolution of electronic research and development technology, driven by stronger and faster functions, consumer electronic products are constantly introducing new ones. As far as scanners are concerned, they are not only designed towards the trend of light, thin, short and small, but also more Focus on high-resolution and high-speed scanning requirements. In the scanning system, the optical scanning module using optical imaging architecture and image capture technology is the most common scanning tool. Generally, the flatbed scanner on the market has an optical scanning module that moves along the scanning direction to scan The documents on the light-transmitting platform are scanned, a...
