Mach-E rear motor teardown by Sandy Munro

[SteveJo]

Gotta luv Sandy, engineer and epidemiologist extraordinaire... "Covid's coming back so tip those cahiers ."

Munro does not understand inverter design for EMC, that's clear.

Ford will be making their own motors and powertrains:

I watched it and found it interesting. But really, saying there are over 500 parts when they are laminated in one part is pretty ridiculous. Sandy is like a grumpy muppet, continually complaining about fasteners, and dissing other engineers who are not there to explain to him why they did what they did.

But, I still enjoy seeing the teardown.

Cool video that I found from the link above, showing Ford assembly (not Borg Warner) of F-150 motors https://media.ford.com/content/fordmedia/fna/us/en/permalink.html?VideoId=6255799100001

Sorry, I see Bong Wannen

I saw Bong Warmer

I'm surprised either of you saw anything clearly through all the smoke after that Bong. ?

That's funny. I didn't see any guys dropping screws into the wrong place like Sandy said is happening. They must be hiding this. It simply cannot be that Sandy has a wild hair you know where and is referencing 30 year old manufacturing processes and things he has no clue about. After all, everything should be held together with clips. Unless it has a Tesla logo on it.

Now, I've finally lost all respect for Munro.

He has to know (or SHOULD know) that the MOSFET array had to have been installed to the board in his hand BEFORE being fastened to the assembly. The MOSFETs would then simply slide into place in the heat sink.

I can tell by watching a video that its obvious.

The fact that he pretends that this is made in the most difficult way possible leads me to think he's not the wizard he thinks he is, or he's making Ford look bad on purpose.

Either way, he should be striped of any of the credibility that he's got left.

Don't confuse poor Sandy with that electronical stuff ?

Interesting, they don't stamp their own logo or brand on their own product? This could be a normal thing in the automotive industry, have no idea

Its typical for whomever pays for the tools to support their contracted orders to put their logo in the tool (die cast mold in this case) so that suppliers can't use that tool to build parts for someone else or even sell aftermarket parts out the back door without Ford's lawyers noticing. OEMs also don't like to advertise their supplier's names if they can avoid it.

Screw dropping doesn't happen because they have plexiglass covers that must be pulled down first (with sensors to make sure you use them) that only have openings exactly where the required fasteners go for that station. Lots of different types of fastener heads (another thing Sandy hates) are used specifically to prevent bolts from being installed in the wrong place because the automated screw guns will only have one specific socket for each specific bolt location. Having different boxes of screws at different stations doesn't slow anyone down because they each have exactly what they need for their job.

I think Sandy must have left Ford before Henry Ford made the assembly line because he acts like one person is building the entire car by his/herself with just a tool box and a box of parts.

If Munro were to actually have input into the design of an electric vehicle, it would have the bare minimum amount of fasteners, all delicate high voltage connections in the electronics would be friction/pressure fit with no permanent mechanical connections, the dedicated oil cooling system would be reduced or eliminated "because VW did it," and all manufacturing processes would be designed according to Sandy's non-applicable, 30+year out of date education and professional experience. I'm happy to have extra fasteners, welding, and other "unnecessary" components that confuse Sandy since they all make the vehicle better for the customer. His comments are all related to making the cars cheaper to produce, not to improve customer experience or performance.

And will it run after he puts it back together. There’s no way an automotive engineer is an expert in everything. I enjoy watching the tear downs but can tell where expertise and opinion overlap.

I'm coming to the view these video's are junk and almost useless.

I'm really hoping Prof Kelly of Weber State gets hold of a MachE (Ford u listening) and does his painstaking teardown. He takes a year or two to do one though. And know you are listening to a professional. None of this shoot from the hip nonsense, every piece of info has been checked and cleared. And it is a thoroughly enjoyable compared to these. Not only that goes through the entire reverse process too. I have learned so much from his videos.... esp. reassembling the car till it is operational. Every bolt is torqued down to spec and perfectly redone.

Anyone with a spare MachE can donate it to him as well.

I think it will be even more entertaining to watch the videos where they try to put it back together again.

Not sure if you're joking or not but apparently they never put these cars back together. Parts are auctioned off at some point. Dibs on the 15.5" display btw... ?

True, Sandy may be out of his comfort level with electric motors moving cars.

The thing to keep in mind about his videos, whether they're about the MME, the id4, or the Ford Lightning (someday), is that these are all Infomercials. They're designed to sell his services and reports on the cars and little more. Yes, he does try to crowdsource the purchases of new vehicles, but the videos are intended to pique curiosity and drive corporate customers to the real, and very detailed reports. Want to know what those say? You can buy it, just as Ford, Tesla, and anyone else can. They are quite pricey though.

I used to work for a company that wrote those benchmark reports. I'm not sure his commentary will help to sell his services... I sure hope he has an EE on staff.

True.
Except when said supplier has more brand recognition. (Cummins, Allison, Brembo, B&O etc)
Borg Warner is probably a toss up.
Has Ford announced where they are getting the Lightning motors? I know it isn't the Magna E-Beam. I think those are likely going to the last mile van bodies if I remember correctly...
