Hello All, I am looking for a white paper (searched here and did not find) on the subject of pros and cons of Planetary gearboxes over Spur gearboxes. Does anyone here have an idea where I could find such an animal? I thank you all for your time and efforts Fritz

PNachtwey, I do understand that these parameters are to limit the physical system. I am interested on how to calculate the 3 separate oves. Thankk you again... especially fro the 2 pages.

I was under the impression that X or D are position/ displacement, after looking at the equation I do thinkit to be displacement/ position

Hello all, PNachtwey, Thank you for those equations. Please tell me wht the p(t) term is. I believe that v(t) is velocity with respect to time and that a(t) is acceleration with respect to time. Is this correct? Fritz P.S. I am so very gratefule to all for their posts and willingness to share.

Pnachtwey, I do not follow you. I am looking for the way to calculate these... I have found some more rticles and now I am a little further along. I believe that what I am asked to find is a first order and a third order motion profile. And from these I must derive the max accelerations... Is...

HEllo, this brings up some more questions: What is the maximum acceleration calculation for a S-Curve profile? What is the maximum acceleration calculation for a trapezoidal profile? What is the maximum acceleration calculation for a triangular profile? Its been 15 years since I have had to...

Hmmmm I tried to upload an image detailsing what I am trying to convey...

Hello All! Thanks for reading and chiming in on this little question of mine. PNachtwey, are you Peter Nachtwey on PLCS.net? If so I read a psot of yours that is helping me get to the bottom of where I am going with my question. The ultimate goal is to compare the s-curve to the trapezoidal...

Thank you for the response. From what I gather from the servo amplifier user manual the acc/dec of both types of "curves" can be programmed for any particular move. The "angle" is determined by the parameters of acc/dec. What I would like to know since both types (s-curve/sinusoidal and...

Hello All, why would one choose one over the other? I know that a sinusoidal has less "jerk" than a trapezoidal, but what other factors are there? Thank you

Thank you all for your input and suggestions. I think that I should / will start with the P.E. exam. Is there a study guide available? The reasons for my interest initially in the BSEE vs BSEET is whilst searching fro other employment, I saw a feew requests directly stating "We seek BSEE and...

Hello all I would like to earn my BSEE. I hvae been working under the BSEET since 1993 and would like to make that change. I live in Chicago illinois and would like to hear some thoughts and suggestion, if you would be so kind. I thank you for your time and effort. Fritz
