Farfle
100 kW
Hello all! I have an exciting project to share with you!
So, Farasis purchased the DP1E (the zoomy portland-made carbon fiber track car that Luke, myself and a handfull of others raced at refuel last year)
Anywho, right now Its got a crappy Remy HVH250 that makes a super lame 100KW and needs a really dumb 300 volt battery to get said lame power. So, leveraging some already amazing motors, I am making a six-wide 75-7.
The stock 75-7s are 6 turns of 24 paralell strands of 18Awg.
This motor will be a 75-42 by zero's nomenclature and because its six stators wide, i am keeping the same Kv and reducing the turn count to a single turn. One turn of 144 paralleled strands, which will be divvied up into 6 24 strand groups each going to its own 420A controller. This should result in about 300hp to the shaft and not at lethal voltages. it just takes 2.4 KA to do it, which is a simple thing to do instead of designing in three times the failure points in BMS's and such.
Today, I got the stator lamination stacks removed from six 75-7s. We used an end mill to score the cases until they fractured open (Surprised me first go-round, they must be a pretty good press-fit), then we pried them open and they pulled right out.
