My career has nothing to do with auto repair/engineering but I've watched several of your videos just because you're a great teacher. Thanks for putting out these college-level demos on KZread!

The machined dots on each planet are only for assembly purposes. It you don't line them up they won't go together. If that wasn't enough trouble, the tooth flanks of the large and small gears of each planet must be timed to each other also. If not, one planet takes most of the torque and the other two just clack around in the backlash. Compound planetary gear drives like this are also used in wind turbines as speed increasers too. Please continue to post stuff. I eat it up, if you haven't guessed by now.

A mechanic who stops learning after finish apprenticeship, will be a useless mechanic long before retirement. Any mechanic - like any trades person or any professional - needs to keep up with changes in their field, and this motor technology is just one of those changes. Institutions like Weber State can provide that training in specific areas to mechanics to stay current - a whole new generation is not needed.

This car has one pedal driving and the lights come on without stepping on the brake pedal, so where would you start if the brake lights don't work or randomly flash? I am a skilled tradesperson, my Dad owned a service station and I grew up fixing cars, I have several college degrees, and I have worked at Chrysler, and now Ford for 40 years, I have spent a lifetime building cars, repairing cars, and making hot rod cars, and if I was 25 years younger I guess I could be a KZread star dropping LS1 engines into G-body cars but learning to work on this car is going to be a process for me and many other will not want to, and thousands of mechanics will struggle, be unable to get training and retire.

Transmissions became automatic and later electronically controlled, disk brakes replaced drums, emission control systems were added, electronic engine management systems replaced carburetors, independent suspensions replaced beam axles, and many other changes have been made in cars without making entire generations of mechanics obsolete... although many of them whined and predicted the end of the world with each change. Most of the vehicle (suspension, brakes, steering, body) is the same whether the vehicle is driven by a gasoline engine or an electric motor.

In the inverter current rating discussion starting @32:33, there appears to be confusion between motor current and battery current. The inverters are rated in amps RMS of AC current supplied by the inverter to the motor, while the fuses are presumably in the DC link (circuit) between the battery and the inverter input (note the DC voltage rating). Those currents can be very different, especially at low motor speed where low voltage is needed, so the same power in the DC link and in the motor can be a much higher current at a much lower voltage in the motor, compared to the relatively constant high voltage in the DC link.

That's awesome. Thanks for showing us. It wasn't obvious to me that it would need to be timed. But yeah that makes sense given the reduction is happening :) I love it. And I love that it can be sourced! I wasn't very impressed with the mach-E overall, but I do like this drive train/inverter setup. Castings are nice looking too. Seems like a very compact robust, and serviceable system. Makes me really happy. Love your videos as always.

very smart and impressive diff/gear reduction system. almost all the forces generated by the gear reduction is contained within the rotating assembly it self rather then having a 2nd or a 3rd axle that the casing would have suport. And for a manufacturing stand point you only have 1 axle with 3 precision bearing surfaces that has to be machined in the case.
