9n6p yyy


Good afternoon, a friend asked to rewind the motor for the boat (Skorpion 22 16, 9N6P) was reeled
Classical circuit AБВ AБВ AБВ

I want to try AБВ / AБВ / AБВ (YYY)

Tell me how to connect the leads of the coils correctly.
Or tell me which circuit is better to use for this motor configuration
Thank you in advance.

Hi
I think you are speaking of a Scorpion HKII 2216-xxx
Yes it is a 9N6P
YYY (all three phases in parallel) is a config providing a high Kv
The original is D (all in serial , delta connecting)
if 12 turns Kv = 3350 rpm/V
* the first way to get your desired Kv is to change the number of turns, keeping D (all serial) connecting
You can use the freeware "turn calculator"
What is your desired Kv (rpm/V)

Thank you so much for your prompt response, yes, the Scorpion HKII 2216-12 motor, but already rewound by someone.
It is not possible to measure KV, the winding is destroyed, I counted 7 turns by heart, comrade claims
Before the breakdown, the KV was 3400.
I need to reel 2850 - 3000 kv
You will have to make a test winding with a thin wire.
I will try D and YYY, measure the resistance, and then decide which circuit to use.
Only I don't know how to connect the end of the coils at YYY, if it's not difficult, please tell me
Information from the manufacturer
Specifications [HK-2216-12]
Stator Diameter 22.0 mm (0.87 in)
Stator Thickness 16.0 mm (0.63 in)
No. of Stator Arms 9
Magnet Poles 6
Motor Wind 12 Turn Delta
Motor Wire 12-Strand 0.21mm
Motor Kv 3350 RPM / Volt
It turns out 12 turns per slot.
With D 7 turns per slot, KV should be 5742
It turns out for D, KV about 2850 you need 14 turns per slot.
Most likely YYY has many turns and the wire will turn out to be very thin, you need to use the original D

Hi MSER
If you want Kv around 2900 rpm/V
Try to stay D
Number of turns = 12 x 3350 / 2900 = rounded to 14 you are right
wire try first (temporary coil) a diam to fill the slot at maximum with 14 turns
---
for info about YYY
First connect three coils "A" (or B or C) in // , respect A_in ; A_out
... then connect in star

Thank you, I'm starting to wind the test winding D, 14 turns

I made a test winding D of 14 turns per tooth, got a strange result KV 1722 (emeter switched to 6 magnets)
It turns out that I uncoiled the motor and 7 turns were wound on the tooth (I counted carefully), the friend said that before the KV winding broke, it was 3400.
It turns out 7 * 3400/14 = 1700
What I got when winding D 14 turns.
For KV 2850 - 3000 8 turns must be wound.
From all of the above, one thing is not clear, the factory winding of this motor is 12 turns per tooth and KV = 3350, the numbers in my head do not converge.
And I still did not understand the connection diagram YYY (First, connect three coils "A" (or B or C) to //, observe A_in; A_out
... then connect to the star)
If possible more information ...
Thanks.

Hi MSER
Maybe for Scorpion stock HK 2216 the windings are 12 conductors per slot (6 turns per turn) ?
I have never dismantled one

About YYY
Very easy to understand
Consider 3 coils "A" there are 6 ends A_1_in, A_1_out, A_2_in, A_2_out, A_3_in, A_3_out
paralleling means :
connect // A_1_in, A_2_in, A_3_in --> A_in
connect // A_1_out, A_2_out, A_3_out --> A_out
same for 6 ends B and 6 ends C leading to B_in, B_out and C_in, C_out
Then connect Y the 6 //ends
pigtail = A_out, B_out, C_out (or all _in)

Thank you so much, I will try.
I will let you know the result.

Wound D, 8 turns, per tooth, wire diameter 0.75mm
V = 10.93
A = 1.6
PRM = 31720
Wt = 17
kv = 2902
Ω = 0.040
Thanks for the help

Hi
I suppose it is Rm = 0.040 ohm (40 milliohm)

Good afternoon yeah
Rm = 0,040 Ом (40 milliohm)
I would like to have less winding resistance.
It remains to balance the rotor and put it on the boat
