meepmeepmayer Posted January 17, 2019 Share Posted January 17, 2019 (edited) According to @EcoDrift's comment on the disassembly video, the mosfets used in the Nikola are called HY3712P and the package seems to be called TO-220. Someone more knowledgable must tell us what that means and how they compare to the TO-247 and the old Tesla level mosfets. Max current seems to be 170A but I really don't know how to properly interpret the data sheet I found: https://datasheet.lcsc.com/szlcsc/HUAYI-HY3712B_C330371.pdf Credit goes to @eddiemoy for asking about the mosfets first Edited January 17, 2019 by meepmeepmayer clarification 2 1 Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted January 17, 2019 Share Posted January 17, 2019 Anyone know the Tesla and MSX mosfet designations? Not the package names? Trying to find data sheets to compare to. Found 200A rated/nominal/continuous and 600A max for the MSX ones - compared to 170A rated/585A max (???) on the Nikola ones - but not sure if these numbers are correct. If they are, it's not such a big downgrade as it may seem. 3 Quote Link to comment Share on other sites More sharing options...

No, just smaller ones compared to the MSX (there's nothing new in the video compared to the extensive photo disassembly article). But there seem to be 12 (screws in the middle of the board, just like the MSX board which only seems to have different mosfets but is otherwise the same) . I believe the 6 might be the MCM5 (3p instead of 6p battery = half the current = half the mosfets, maybe?) or maybe thast's just a rumor, never seen a picture of an MCM5 board. So basically a 15% downgrade from the MSX, which isn't that bad. (Hardware downgrade, they seem to have a new motor control algorithm so that will do something.)

If they are, it's not such a big downgrade as it may seem. the mosfets look to be pretty significant. i know the mosfets are used to switch current to the different phases in the motor to simulate a 3 phase motor. not sure if they are used in parallel. if they are nothing to really worry about. that 6x 170amps or 1020amps.

They look so small compared to the TO-247 huge blocks, but if they're good (someone knowledgable please tell us), I'm happy with that. Now if the wheel was smaller and cheaper, it would be the perfect 16 incher spec-wise. 1 Quote Link to comment Share on other sites More sharing options...

Ohh at first I thought you were putting in a bid to @Jason McNeil on that test KS18XL demo unit... Until it hit me that you count in us$ and that might be a little high price to pay, unless you had it signed Approved by The Marty wheelman in gold. Since he is famous.

"Only" 10% difference is in line with the diode of evil in your MSX. So both wheels seem to have the same range under normal circumstances. Chooch-used, indeed.

I wondered at first if Marty had somehow spent $20k on wheels. Not quite there yet... or is he? - To stay on topic: I'm sure the next wheel will be a Gotway again. It's called Nikola (or Nicola? Nicole? Something like that.). 1 1 Quote Link to comment Share on other sites More sharing options...
