Electronic components consideration in mechanical design

[sotkoon]

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.

Hello!

As a scientist with expertise in electromechanical systems, I am happy to address your questions.

(1) The motor can have a significant impact on electronic components and wiring in terms of creating electromagnetic noise. This noise can interfere with the electrical signal and potentially lead to malfunctions or failures in the system. To reduce this noise, shielding can be used to block the electromagnetic waves, and filters can be installed to suppress the unwanted frequencies. Proper grounding and routing of wires can also help to minimize noise.

(2) Vibration and shock can greatly affect the life and performance of electronic components. Excessive vibration can cause physical damage to the components, while shock can lead to malfunction or failure. To mitigate these effects, it is important to choose electronic components that are designed to withstand vibrations and shocks, and to properly secure and isolate them within the system.

(3) In a robotic system with rotating parts, the best arrangement for wiring would be to use flexible and durable cables that can withstand repeated motion. Cable carriers or cable tracks can also be used to guide and protect the wires. Additionally, it is important to consider the length and routing of the wires to prevent tangling or strain on the connections.

For further reading, I recommend the book "Electromechanical Systems and Devices" by Sergey Edward Lyshevski. Additionally, websites such as IEEE Spectrum and Electronic Design can provide valuable information on electromechanical design. I hope this helps and best of luck in your work!
