Servo Motor Sizing Basics Part2 - Technical

[@michaelfiander1866]

Excellent video speaking as someone who has never used a servo motor before

[@davidmikesell6851]

@Eli Grobin: Yaskawa is here defining "pitch" as rev/inch, instead of the (much more common) inch/rev or mm/rev. With this definition, a higher "pitch" does give you a finer thread ball screw. Their definition of pitch was confusing for me also. At 2:28, I was expecting to see the pitch term P in the numerator.

[@YaskawaAmerica]

It is possible that he is referring to ball screw lead instead of pitch. The friction torque units appear correct in LBFF-in. Here is more information on lead versus pitch. hwww.thomsonlinear.com/en/support/tips/what-is-the-difference-between-pitch-and-lead-when-referring-to-a-screw#:~:text=for%20e%2Dcommerce.-,What%20is%20the%20difference%20between%20pitch%20and%20lead%20when%20referring,ball%20screws%20are%20typically%20specified.

Thanks for your voluntary to teaching

[@adolfkarthick6912]

Thank you my friend its very useful for a machine designers and please upload the more videos like this

[@sasasasa711]

Please do a tuning and set up video on rack and pinion gantry load tuning with 2 motors for y axis

[@ДенисВоробьев-щ3ч]

Very clear and useful. Thank you very much.

When you reference the change in pitch around 6:50, what are the units of pitch? Your example references a larger pitch but then shows a finer thread ball screw, and this confuses me. I would think going from pitch of 1.5 mm to pitch of 1.0 mm would decrease the effect of the linear components inertia on the total inertia.

👍🙂very nice

Topz excellent learnt alot

I didn't see "t (sub m)" defined in Motion profile! What is this variable?

[@YaskawaAmerica]

The tm is the time required to complete the motion profile, excluding the dwell time. In the example from the catalog, it is labeled as feeding time. Here is a link from our Yaskawa Solution Center: solutioncenter.yaskawa.com/selfservice/viewdocument.do?noCount=true&externalId=DMSD-MotionProductEngineering-YEA-KAEPS80000042-YEA-KAEPS80000042Kpdf&sliceId=pdfPage_393&noCount=true&isLoadPublishedVer=&docType=kc&docTypeID=DT_MARKETINGDOCUMENTS_1&stateId=2830&cmd=displayKC&dialogID=147806&ViewedDocsListHelper=com.kanisa.apps.common.BaseViewedDocsListHelperImpl&openedFromSearchResults=true

Thanks

[@pedrocasillas9412]

Excuse me Sir, why is the gravitational acceleration included in the rotational inertia equation? min 8:17

[@YaskawaAmerica]

It is all about unit conversion. US Customary Units are implied in this case. Gravitational acceleration is included at 6:30 to convert weight to mass. At 8:17, to be consistent, the assumed units are also weight per cubic volume (for example lb/ft^3). We might have made this more clear by expressing the term as ρ/g. Hope this helps.
