NEU 1515 2050 2d or 2200 1y

[Margeibel]

Reading the posts I see a lot of people running NEU 2200 1y motor. Can someone explain the difference between 2050 2d and the 22001y. I looking to put one of thoughts motors in a Genesis. I have 180 esc 4s and 5s batteries. Upgraded strut, flex cable and shaft 3/16. Working on some re enforcing the body. Looking for speed in the 50s.

The biggest difference you would notice is the Kv. The 2050 will swing a slightly larger prop, the 2200 will spin a slightly smaller prop faster. Here is what the motor maker Aveox had to say about the two different winds. Read carefully, he is mostly talking about the advantages of building the two different motors, not the difference in performance. I'd get the 1Y motor.

At Aveox, we have essentially deemed the Deltas as secondary to Wye winds in any application, except where a very high degree of uniformity in both directions is very important. Things like robots that move in both directions equally put up with the efficiency losses. Since the motors are very insensitive to timing changes (unlike the Wye winds), you don't have great performance in one direction, and poor in another(without adjusting the timing). You have good performance in both. (but it is not worth the losses in a model)"

So basically the Wye will spool up faster and reach its top RPM a bit faster than the Delta wound motor. The Delta wound motor also consume more amperage than the Wye motor. If you want a hi-torque motor, the Wye-wind will let you do it with few turns. If you want speed, the Delta motor will let you do it without having to use difficult, thick wire or mess with parallel strands.

I am not understanding that, can someone translate that into newbee English. Thanks

I think it was a typo. Im sure the end part is worded backwards

As Fluid has underlined in his post: this is from the motor maker's point of view. The Y motor has a better 0-60 performance ( more torque in a given kv or turns---some makers rate their motor with turns instead of kv) , the D motor is good with uniformed speed in both directions without the need to have timing complexities. The wire gauge and parallel strands are the windings in the stator.
You can think of this as two internal combustion engines with the same/similar displacement but tuned for different purposes. One has 0-60 as priority, the other one is a high rpm screamer.
Having used a Leopard 4082 2000kv D motor, I now prefer Y motor. I have a Neu 15151y in my Mean Machine and a Castle-Neu 15151y, love them both.
I have read this many times and this is how I come to understand this paragraph, and also my observation with the motors I have . I hope I am right or at least partially correct. Never is my intention to steer anybody wrong. Let's see if my head is on the chopping block come morning!

The D wind also has much higher Ripple current back to the ESC, not good.

Thanks I got it now.

Higher Ripple Current I did not not know that thanks.

Obvioiusly you have not compared many similar motors. Apples to apples - my 1527/1D (2300 Kv) has less ripple than my 1527/0.5Y (2500 Kv) does. Generalized statements comparing the draw of two winds are often not completely accurate - that's why I didn't give one to the OP. I haven't tested the OP's motors so I don't know.....

I've run the D's and the Y's in heat racing and trials. IMHO if your is boat set up well, any difference in amp draw and ripple is negligible for the majority of boaters. I pick a motor based on the kv that I'm targeting. Like Jay said, the KV is the most important difference between the two motors you are looking at and you will have to prop accordingly. Oh... and don't forget the D winds like very low timing while most Y's somewhere around 10-15 degrees.

Jay, my source was Steve Nue in 2004, the key to the conversation may have been - at the same amps. I was looking at SAW at the time. There were papers on the internet showing the coil effect of the delta winds.
