A lot will depend on your application. In some instances earthing the motor frame can help to reduce EMI noise generated by the motor. This most will effect the equipment around the motor and not necesarily the motor itself. Also, earthing the frame is mainly done for safety reasons. In...
If you were to use a 200mF cap you would experience around a 10V ripple at 300A load current. 100mF cap will provide approximatly a 20V ripple. You will never get "perfect" DC. The larger the capacitance you use, the less ripple effects you will get, but in the end it all depends on how much...
The size of the capacitor (and/or inductor) that you would use will largly be dependant upon the current draw. What kind of current does the machine draw?
Thanks for the info. I'll look into both of these and see where I end up. To be honest I never would have thought to get an assistant who could specialize in a particular area so that I could completly off-load a section of my work load.
Any ideas on how to avoid people reviewing the design...
I am currently looking after the development of an engineering team in a fairly new medical design and manufacturing company. Included in my responsibilities are complete electrical/electronic design, production and assembly line setup, process and procedure creation, partial mechanical design...
