RE: Which chinese factories make various brushless motor brands?

COMPARISON OF THE DIFFERENT BRAND MOTORS MADE AT THE SUNRAY TECHNOLOGY FACTORY

INDOOR-SIZE MOTORS (21mm and 28mm diameter)
(listed in order of weight, ascending Kv, and number of turns-descending), (LP =LiPolice)
(For Turnigy SK3: Stated "Can length" is 1 to 3mm longer than stator length; and can be used to identify stator length of each motor;
"2118" -size motor has 1705 stator; "2122" motor has 1709 stator; "2822" motor has 2205 stator )

15g, 16g
(these motors have a 1705 stator -i.e. stator is 17mm diam, 5mm length)

SunRay 1705-1825Kv 14T, 16g=LP-1705/14T-1825KV=Infinite A1705-1800, 14T=HYPERION Z1705-14T 1800 KV=Foxy C1705/14 1825 Kv

Gens ACE Mars BL2118-2050KV, 16T, 16.5g(-with Kv 2050, would expect less turns than 16T ?)

SunRay 1705-2275Kv 11T=Turnigy SK3 2118-2250kv, 11T=LP-1705/11T-2275KV =Infinite A1705-2250, 11T=HYPERION Z1705-11T 2250 KV

Hacker 15g, A10-15 S, Kv 2320, ?15T, 12pole, D21 L21=FURY SA-10-15S / 2320Kv, ?15T, 15g=~Turnigy SK3 2118-2250kv, 11T=~LP-1705/11T-2275KV =~Infinite A1705-2250, 11T=~HYPERION Z1705-11T 2250 KV

Turnigy SK3 2118-2750kv, 9T

Hacker 15g, A10-12 S, Kv 2900, ?12T, 12pole, D21 L21=Fury-SA-10 ?12S / 2900Kv, 12T

Turnigy SK3 2118-3100kv, 8T

(Note: These 15g, 16g motors are listed in order of Kv. However, in this small section, quoted number of turns does not completely correlate with Kv -as it does for ALL other motors listed, up to 60-size motors. -I suspect theHacker A10-15 Sis actually an 11T motor, and that the Hacker A10-12 S is probably more like an 8T or 9T motor ...)

20g
(these motors have 1709 stator)

Hacker 20g, A10-13L, Kv 1200, 13T, 12pole, D21 L25

Hacker 20g, A10-9L, Kv 1700, 9T, 12pole, D21 L25=FURY SA-10-9L-1700 Kv, 9T =~SunRay 1709-1580Kv 9T=~Turnigy SK3 2122-1570kv=~LP-1709/9T-1580KV=~Infinite A1709-1500, 9T=HYPERION Z1709-9T 1500 KV=Foxy C1709/09 1580 Kv=APACHE APM10-9T, Kv1700=Gens ACE Mars BL2122-1580KV, 9T

(NOTE:Hacker A10-9 Lhas a quoted Kv 1700; However, other identical motors with the same 1709 stator and 9T, quote Kv 1500 (Hyperion); Kv 1580 (LiPolice LP); Kv 1580 (Gens Ace)
DriveCalc shows that for these small motors, the measured Kv may actually be about 100 different from the Kv quoted by the brander / retailer.
For instance, DriveCalc shows that the LiPolice Z1705-11T 2250 KV has a measured Kv of 2461 rpm /V -200 more than the quoted manuf Kv;
It seems highly likely that the actual Kv for the Hacker / Fury A10-9 L is more like 1600;and also that Kv of the Infinite / Hyperion1709 9T will be more like 1600 -this will make the Kv's of all these motors very similar )

Turnigy SK3 - 2122-1800kv, 8T
