This is the sensor socket:
isnt the NTC the temp wire?

Dont know if the winding plays a huge role in our application but i might be wrong
maybe anyone can confirm this?
As far as the KVs are fitting your setup it should be fine.
Ive heard tht D winds can run hotter under very high end setups (RC Cars 170MPH builds) but im not sure if this is really a thing

Certainly looks like a temperature sensor wire. I only know I explicitly asked about getting temp sensors and they told me they could only add hall sensors and that was after checking with the factory. Have you been dealing with the US distributor?

no im located in europe so i ordered them from germany.
Ill check my motors as soon as they arrive and post a pic of the sensor plug.
except you dont get temp readings its not affecting a smooth startup am i right?

I think it would only affect startup if you were using a VESC-based ESC and using VSS which I believe relies on the temperature sensor.

I also shared that image you posted above with the US distributor and asked them to confirm.

ok yeah would be good to know thx man!!
Xlx2 has an adjustable shut down feature for motor temp. I will work with or without.

From more reading I’ve done trying to learn about RC motor applications, it seems like Y wind might be a more reliable option for us pushing max power. Not positive but it seems like the general consensus.

The 5694 SSS motors are Delta wound.
56112 2028castle are Wye wound
Delta motors make more power per copper and iron mass.
Copied off the interwebs:
For a wye wound motor as compared to a delta wound motor, presuming each phase resistance is the same, between any two phases, a delta wound motor has 1/3 the resistance as compared to the wye . The wye-wound has higher resistance and higher inductance, better for drives with lower switching frequencies.

Delta or wye make the same power. Motor km is independent of the winding
Being practical it makes sense to state wye can produce more power because when powered it’s just one circuit and delta is two and those two will likely not be balanced as the windings won’t be identical and have stray voltages between them which is a loss. In theory they should be the same but in practice it’s hard to get the delta circuits the same inductance and voltage
1/3rd the winding resistance will be a different kv but same km.
Motors aren’t wound delta or wye, they’re terminated wye or delta.

so i think in our applications its not affecting the performance of a board if o have D or Y winded motors. right?
Not really. Although wye are often said to run smoother and maybe have less cogging at low speed

yepp which then again is irrelevant when you sensor them

so i think after all this research being done it really doensnt matter too much which winding you take especially when you took sensored motors

different windings do effect the “winding factor” which is the magnetic circuit and some are more efficient but delta or wye isnt the winding and is the termination.

Watts is the same for same Delta vs wye on the same winding count. , more amps using a lower voltage with delta to get there
Different Kv for the same number of turns on delta vs wye
You need to compare the same Kv motor, for example 4TW is 800 Kv and is rated at 220 A
7TD is 850 Kv and 243 A
Is not the same due to the Kv not being exactly the same

Does the termination affect core saturation at all? Since spreading the magnetic field across more iron could plausibly let the total torque increase.
