Description

technical field [0001] The invention belongs to a method and a device for implementing an electronic gear by using an electric transmission control system instead of a mechanical transmission chain, in particular to a device and a method for realizing the electronic gear function of a Switched Reluctance Motor (SRM for short). Background technique [0002] Gears are widely used in machinery, metallurgy, papermaking, and other industrial sectors due to their accurate transmission ratio, large transmission power, and stable transmission. However, in some application fields, gear transmission has defects such as large transmission error and difficulty in realizing distributed transmission ("Research and Application of Electronic Gear Box System", 2001.3 "Mechanical Design and Manufacturing Engineering"). For example, in the printing field, due to the transmission shaft The distortion and gear gap will affect the tension and overprint of the printing machine, which will directly...
