Electronic cams can be used in various fields such as automobile manufacturing, metallurgy, mechanical processing, textiles, printing, food packaging, water conservancy and hydropower. To For example, in mechanical processing, it is of course the easiest to use electronic cams to replace bulky mechanical cams. Replace the mechanical cam on the motor shaft with a resolver for position feedback, and send the signal of the electronic cam to the controller to realize all the functions of the original mechanical cam. There is no doubt that the system using electronic cams has higher machining accuracy and flexibility, and can greatly improve production efficiency.
