The KV rating is also related to the stator rotor pole counts. While V2 has a lesser count, so it has to travel more quickly to achieve the synchronous speed. Thus increases the KV rating with reduced torque. But in this case, V1 and V2 are different in magnet arrangements and so the V arrangement of V2 compensates for the reduced diameter and pole pairs. V1 is providing less kV rating with better torque in straight magnet arrangements and increased diameter and reduced copper. So in my understanding, V1 will be cheaper and V2 will be expensive and with improved performance.
@@de-bodgery Yes. And it has the original QS design we can see in other models. From flat magnets arrangements to V shape, which has a far better concentrated field than the flat arrangement. Winding is more thicker with higher Parallel paths et.... And also as you mentioned they improved a lot.
If you still have Nuc measure inductance with LR detect on assembled motor, it is not very accurate to measure with no rotor since magnetic path is open. There are two inductances on rotor and interesting how much mtpa profit v2 will have
Have you noticed any difference between the 1200 w TP 128 and the 1800 watt version? I'm talking about weight, number of magnets and stator poles, lamination thickness, wire diameter and number of turns.
Not sure why you posted this in the QS165 video. TP128 comes in 1600w and 1800w versions...not sure what a 1200w version is so I can't speak about that. 1800w version has a taller stator than the 1600w version and longer magnets. Otherwise they are the same. They also come in 3 Kv's so turn counts can be different too.
You are talking about winding resistance an awful lot but you have yet to mention lamination thickness or wire awg in regards to skin effect. What is up with that?
I have seen a couple of other motors that are 6 phase like this is. I've been wondering about those advantages if any myself. This feels like a short cut to me for this specific motor to get more amperage. Other motors with 6 phases, they are intended to be run by dual controllers. I'm not a motor expert! I hope that some people that are will weigh in and tell why this is good or bad because I don't know!
@@vasilisk8944 Interesting! I've seen 6 phase motors and used one as you know. This would be the first time I ran into both sets of phases wired together.

v2 outperforms v1

I'll be doing this with a VESC 100-250 soon.
بالتوفيق اخي العزيز

Feel free to make suggestions.
Can you do a KO motor?
Sure can! Meant to get to the measurements video tonight for the FSPEC, but ran out of time due to other things.
It's a process of discovery for all of us, keep up the good work. Electrically speaking, is there any advantage by going with parallel WYE?

Car motor on Nissan Leaf also dual wye, i tink it is just a way to optimise winding

@@de-bodgery well i guess chinese finally reachin some korean/japanese technologies :D
@@vasilisk8944 China copies everything...that's probably all they did.
