AI Thread Summary
To calculate the driven load inertia for regenerative braking, the equation WK2s = WK2m + (WK2L / GR2) is used, where WK2m is the motor rotor inertia and GR2 is the gear ratio. The motor rotor inertia is given as 2.872 lb/ft^2, and the gear ratio is 52:1. To find the driven load inertia (WK2L), rearranging the equation is necessary. Resources like hpwizard.com may provide additional insights into calculating rotational inertia. Understanding these components is crucial for accurately determining the total system inertia in regenerative braking systems.

Hey, how do you calculate the driven load inertia that you need to calculate the total system inertia. I know the motor rotor inertia is 2.872 lb/ft^2 and the Gear Ratio is 52:1 but I can't seem to figure out how to get the driven load inertia for the equation:

WK2s = WK2m + (WK2L / GR2)

Where:
WK2s = total system inertia
WK2m = motor rotor inertia
WK2L = driven load inertia
GR2 = gear ratio (defined as motor revolutions/driven load
revolutions)

Can anyone shed some light on this for me? It would be greatly appreciated.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
