Hi all, I am fresh mechanical design engineer. I have some questions regarding the electrical components and wiring issues in mechanical design: (1) For an electromechanical system, how serious will motor influence the electronic components and wiring in terms of creating electromagnetic noise to electrical signal? What are the methods to reduce the noise? (2) How will vibration and shock affect the life and performance of electronic components? (3) In a robotic system involving rotating parts, what is the best arrangement for wiring to permit a wide range of motion? Thanks a lot for your comments and advise. Any suggestion on further reference books and websites is much appreciated.
