Mustang Mach-E GT Motor Details

See the Marvelous Motors of the Ford Mustang Mach-E GT. These motors are more powerful than Tesla Model 3 and Y motors. The front and rear GT motors are identical, with a few minor differences. See how to set the timing on a compound planetary gear set! This video is the sixth in a series about the Mustang Mach-E GT.

QUESTIONS FOR TEACHERS
1. What type of motor is used in the front drive unit?
2. What type of motor is used in the rear drive unit?

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 YouTube!

[dangerdavefreestyle]

Your complexion is looking better Mr. Kelley, I hope you continue churning out these videos for many more years because they are golden.

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.

Kudos to Ford and Borg Warner for donating the motors. Another great video. Thanks

This is the USA at its best: a manufacturer donating a current piece of kit to a uni, the uni putting out a video explaining all the stuff on the Internet for everybody to see and learn. Thank you!

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.

You are the protagonist of the best free online automotive school. I like your smile along with the new technology.
Thanks also to Ford for this donation.
Mach-E has a starting price of 61, 000 Euros, including all taxes in my country!!!
God help !
Many thanks !

With instructors like yourself, I foresee Weber State being very successful in its endeavors to teach about electric vehicles. Wonderful series.

[Kebekwoodcraft]

As a retired ford mechanic for about 25 years from Quebec, am still interested in learning probably same as my time the exact diagnostic is the key of a good mechanic, I really enjoyed your video thanks ☺️

[kjkromm]

A whole new generation of mechanics is going to be needed.

[heater]

Wow, what a wonderfully compact unit. Motors, sun and planet gears, differential, inverter and all. Thanks for the. literally, insight into that unit and the great explanation.

[Maltanx]

Thank you Professor!
It's a bit sad to know this will be the last video on the Mustang-E GT.
I'll wait eagerly for the next series of videos!

Audi e-tron is also using compound planetary gear set for the co-axial variant

This channel and Munro Live are the best technical EV channels. Thank you Prof. Kelly.

[mackebest]

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.

[TheDisgruntledMechanic]

Great end to my day! Another Weber Auto video! Thanks Prof. Kelly!

[Stefan_Dahn]

37:10 "three phase training" caused a smile due to the double meaning in this matter. Thanks Prof. Kelly. 👍😁👍

[chandpriyankara]

Thank you.. this is the only channel I've enabled notifications... not a mechanic, but I enjoys how you clarify with reasoning for each steps.

[Mach-EzorGT]

This is the only way I ever want to see the motors for my Mach-E GT! Thanks!

[elainecurrie]

Regarding timing planetary's. The Model T (1909 to 1927) transmission gears have to be timed when assembling so that the set will go together.
