Default Rewinding a brushless motor for nano cpx

Wondering which type of winding is the most efficient. Wye or delta.

If I rewind 2 brushless motors for 16000kv, one for using Wye winding and the other for using Delta winding. Which motor will be more efficient?

Neither is particularly more efficient per se, they're just different.

I think for such a high Kv it would be best to go for Delta because Delta has a higher kV for a given number of turns. Thus you could go with a slightly thicker wire, allowing for (probably) more efficiency and/or power.

Not sure how my knowledge relates to these small motors. But in the "Big Brother World":


Delta wound motors are used for low speed and high torque situations. If you operate these motors at maximum speed, they build up heat very quickly. And use a lot of current.


Wye wound motors are the most common. And have more torque in the middle of the speed curve. They handle the higher speed easier than deltas. Don't build up as much heat. And use less current.


In my field, we use a few Wye/Delta Motors for starting heavy loads. We start the load in Delta for higher torque and lower current (although still quite high considering the load). And then switching to Wye to lower the current and continue the run at greater speeds.
