RE: Which chinese factories make various brushless motor brands?

Updated version:
DIFFERENT NAMING SYSTEMS FOR BRUSHLESS MOTORS:
Here are some of the most common naming systems, or naming conventions, used for brushless motors:

1. STATOR SIZE
The stator of an outrunner brushless motor is the central non-rotating part, which is radially arranged, and which is wound with a given number of turns of copper wire. The outer can with magnets mounted on its internal face, rotates around this stator. Stator arms (also called "stator slots") are always in multiples of three -whereas motor magnets (also called "magnet poles") are always in mutiples of two.
Many manufacturers and distributors name their motors with respect to stator size; For instance AXI, Scorpion, Emax, Pulso, Suppo, Motrolfly and also some motors made in the SunRay Technology factory (e.g. Z-series Hyperion, LiPolice, Foxy, OK Hobby Infinite, -to name a few) are all named this way. Worth noting that Pulso motors are basically a copy of AXI motors, use the same stator-size naming system, and are sold in the USA (with small modifications) as Innov8tive Cobra motors. The O.S. motor naming system has a part which uses length of the stator (see later).
e.g. The AXI 2203/52 motor, has a stator which is 22mm diameter, 3mm in length, and is wound with 52 turns of wire.
The AXI 4130/16 motor, has a stator which is 41mm diam, 30mm length, and is wound with 16 turns of wire.
The Scorpion SII-3020-890Kv motor, has a stator which is 30mm diam, 20mm length; it has a Kv of 890 (-and is wound with 10 turns of wire =10T ).
The Z-Hyperion / LiPolice / Foxy / OK Hobby Infinite 2213/20T motor has a stator which is 22mm diam, 13mm length, and is wound with 20 turns of wire.
The Suppo A2820-6 motor has a stator which is 28mm diam, 20mm length, and is wound with 6 turns of wire.

2. EXTERNAL DIMENSION
Some manufacturers name their motors with respect to their external dimensions, usually outer diameter and length.
XYH (i.e. EMP), most Turnigy, Saite, Dualsky,and many other brands, name their motors this way. (-Worth noting that XYH (EMP) motors are sold under dozens of brand names -including Turnigy "standard" and Turnigy "Aerodrive XPSK" -and mostly all these brands also use this external-dimension naming convention for these motors).
Also worth noting that the Gens Ace range of motors, and also the Turnigy SK3 range of motors -even though they are both manufactured by the SunRay Technology factory, and therefore almost identical to Hacker and Torque and Hyperion motors -they use the external dimension naming system to describe their motors
e.g. The XYH N2830/13 motor is 28mm external diam, 30mm long, and has 13 turns of wire (its stator size is 22mm diam, 13mm length -same as a "2213" motor on stator-size).
The XYH N5055/07 motor is 50mm external diam, 55mm long, and has 7 turns of wire (its stator size is 40mm diam, 25 mm length -same as a "4025" motor on stator-size -see http://www.rcgroups.com/forums/showthread.php?t=1724518 ) (This motor was also sold as the old "TGY AerodriveXp SK 50-55" motor and can also be found as an "EMP 5055" motor or "N5055" motor on eBay).
(Worth noting: that some 5055-size motors have a 4030 stator,rather than a 4025 stator ... -for instance, the Turnigy SK3 5055 motors have a 4030 stator, however these motors are actually 59mm long ... -so should really be called a "5060" motor on basis of external dimensions )
The Turnigy SK3 3542-1000kv motor, is ~35 to 37mm external diam, ~42mm long (has 12 turns of wire) (its stator size is 30mm diam, 20mm length -same as a "3020" motor on stator-size). (It is the exact same motor, internally,as: Hyperion Z3019-12T, LiPolice / OKHobby Infinite / Foxy3020/12T-970KV and Hacker A30-12 L V2).

3. THE HACKER MOTOR NAMING SYSTEM 
Hacker motors aremade together with Extreme Flight Torque and Z-Hyperion motors, in the SunRay Technology factory. They are identical internally and also in specs to Torqueand Z-Hyperion motors, and also to the other motor brands made by the SunRay Technology factory. They have a slightly different external can appearance to Torque,Z-Hyperion and the other motor brands -thisis just cosmetic, and the external can shape and colour has no relation to motor performance.
Hacker uses a different and seemingly unique naming system. The first number reflects power level: "20" motors seem to refer to roughly an I.C. 20-size power level, "30" motors refer to I.C. 30-size in power level; whereas "50" refers to I.C. 50-size power level, etc etc.
The second number in the Hacker naming system, refers to the number of turns (winds) of wire on the stator. The final letter in the Hacker name, refers to the length of the motor -either S, M, or L (small, medium, large) (or: short, medium, long).
(Note: Keda motors are basically -poor-quality -copies of Hacker motors, and since they are copies, they also copy and use the same Hacker naming system ).
For instance, the Hacker A10-9L motor, is "10" size, has 9 wire turns, and is "L" -22mm long (its stator size is 17mm diam, 9mm length -same as a "1709" motor on stator-size) (its external size is 21mm diam, 22mm long -same as a "2122" motor on external dimension) (It is the exact same motor as the Hyperion Z1709-09T, LiPolice / OK Hobby Infinite / Foxy1709/9T-1580KV and Turnigy SK3 2122-1570kv, 9T).
The Hacker A30-12-L-V2 motor, is "30" size, has 12 wire turns, and is "L" -42mm long (its stator size is 30mm diam, 20mm length -same as a "3020" motor on stator-size) (its external size is ~35mm diam, ~42mm long -same as a "3542" motor on external dimension) (It is the exact same motor as the Hyperion Z3019-12T, LiPolice / OK Hobby Infinite / Foxy3020/12T-970KV and Turnigy SK3 3542-1000kv, 12T).
The Hacker A50-16-S-V2 motor, is "50" size, has 16 wire turns, and is "S" -52mm long (its stator size is 40mm diam, 25mm length -same as a "4025" motor on stator-size) (its external size is ~50mm diam, ~50mm long -so about the same as a "5050" motor on external dimension) (It is the exact same motor as Hyperion Z4025 16T, LiPolice / OK Hobby Infinite / Foxy 4025 /16T-385KV).

4. THE O.S. MOTOR NAMING SYSTEM
The O.S range of motors also appear to be made in the SunRay Technology factory.
O.S. uses another motor naming system, which combinesmotor external diameter and stator (i.e. magnet) length. The first number refers to motor external diameter inmm, and the second number refers to stator (magnet) length in mm. It has some similarity to the Himax naming system (see below).
For instance, the O.S. OMA-3815 motor is 38mm external diameter, and has a stator (magnet) length of 15mm. It is 38mm long, has a weight of 130g and has 16 turns (its stator size is 30mm diam, 14 to 15mm length -same as a "3014" motor on stator-size); (its external size is ~38mm diam, ~36 to 38mm long -so about same as a "3838" or "3836" motor on external dimension); (It is a similar motor to: Hacker A30-16 M V2, Turnigy SK3 3536-1050kv,Hyperion Z3013-16T andLiPolice / OK Hobby Infinite / Foxy 3014/16T-972KV).
The O.S. OMA-5025 motor is 50mm external diameter, and has a stator (magnet) length of 25mm. It is 58mm long, has a weight of 400g. (its stator size is 40mm diam, 25mm length -same as a "4025" motor on stator-size); (its external size is 50mm diam, ~55 to 58mm long -so about same as a "5055" motor on external dimension); (It is a similar motor to Hacker A50-16 S V2, Hyperion Z4025 16T, and LiPolice / OK Hobby Infinite / Foxy4025 /16T-385KV).

5. E-FLITE MOTOR NAMING SYSTEM
E-Flite name their motors directly, with respect to their equivalent I.C. power level. E-Flite motors are all made by the ChinaHimark factory, in China -they are all ChinaHimark "C-Type" motors.
E-Flite motors have identical specs to the "TACON" outrunner motors sold by Hobbypartz.com (The TACON motors have a different external can and colour -this is just cosmetic) and so it appears that TACON motors will also be made by the ChinaHimark factory.
For instance, the E-Flite Power 10 motor is 35mm diam, 43mm longand has a Kv 1100 (its stator size is 28 to 30mm diam, 20mm length -same as a "2820" or about "3020" motor on stator-size) (its external size is ~35mm diam, ~42mm long -same as a "3542" motor on motor external dimension). (It appears to be the same motor as theTacon "Big Foot 10"2820 1100Kv and Turnigy G10 EasyMatch 1100kv).
The E-Flite Power 46 motor is 50mm diam, 55mm long and has a Kv 670 (its stator size is 40mm diam, 20mm length -same as a "4020"motor on stator-size) (its external size is ~50mm diam, ~55mm long -so same as a "5055" motor on external dimension) (It appears to be the same motor as the Tacon "Big Foot 46"4020 670Kv and Turnigy G46 EasyMatch 670kv).
Turnigy "EasyMatch" G-series motors also use the same power naming system as E-Flite, relating the motors to their equivalent I.C. power level. The Turnigy "EasyMatch" motors are probably also made by the ChinaHimark factory, in China, and appear to be identical to E-Flite motors.

6. HIMAX / HIMARK MOTOR NAMING SYSTEM 
HiMax (also called "HiMaxx" and "HiMark") motors are also manufactured by the ChinaHimark factory, in China. They are distributed in the USA and in Europe by the Maxxprod company, and are sold in Europe as Multiplex Himax, TopModel XPower, and JP Energ C-type motors -these brands are all the same motors. These motors all use a different naming system, which is a hybrid of other systems already mentioned. The first number in the name shows the diameter of the motor, and the second number shows the length of the stator. The third number after the dash, shows the number of turns for each motor.
For instance, the Himax/XPower C2812-26 is 28mm external diam, has a stator of 12mm length, and has 26 wire turns and a Kv 900(its stator size is 22mm diam, 12mm length -same as a "2212" or about "2213" motor on stator-size) (its external size is ~28mm diam, ~30mm long -same as a ~"2830" motor on external dimension) ( -This is the same motor as the E-Flite Park 400, 920Kv motor).
The Himax/XPower C5020/14 is 50mm diam, has a stator of 20mm length, and has 14 wire turns and a Kv 670(its stator size is 40mm diam, 20mm length -same as a "4020" motor on stator-size) (its external size is 50mm diam, 55mm long -same as a "5055" motor on external dimension) ( -This is the same motor as the E-Flite Power 46 670Kv; and also same motor as: Turnigy G46 EasyMatch 670kv; (-theseare a similar, but not identical motor,to theTacon "Big Foot 46"4020 670Kv motor -because Tacon motors are made by the XYH-EMP factory, are identical to Exceed-RC "Monster Power" motors ... ).

7. TORQUE MOTOR NAMING SYSTEM
Extreme Flight "Torque" motors are, of course, made together with Hacker and Z-Hyperion motors, and other motor brands, in the SunRay Technology factory. They are identical internally and also in specs to Hacker, Z-Hyperion and other brand motors. They have a different external can appearance to Hacker and Z-Hyperion, which is just cosmetic, and the external can has no relation to motor performance.
The naming system for Torque motors is confusing, and gives relatively little useful information about the motor. Some Torquemotors are named with reference only to number of turns and Kv; Other motors are named with reference to approximate stator diameter, as well as number of motor turns and Kv.
For instance, the Torque 20T/1030 motor has 20 wire turns and a Kv of 1030. It has a weight of ~55g, external diam of 28mm and length of 30mm (its stator size is 22mm diam, 13mm length -same as a "2213" motor on stator-size) (its external size is 28mm diam, 30mm long -same as a "2830" motor on external dimension). ( -It is the exact same motor as: Hacker A20-20-L-EVO, Kv 1022, 20T;OKHobby Infinite/ LiPolice / Foxy 2213-1080Kv 20T; andTurnigy SK3 2830-1020kv, 20T)
The Torque 2814T/820 motor: the 1st number is "28" -actually it has a stator diam of 30mm; It has 14 wire turns, Kv of 820, weight of ~143g, external diam of 35mm and length of 42mm (its stator size is 30mm diam, 20mm length -same as a "3020" motor on stator-size) (its external size is ~35mm diam, ~42mm long -same as a "3542" motor on external dimension). ( -It is the exactsame motor as: Hacker A30-14-L-V2, Kv 800, 14TandTurnigy SK3 3542-800Kv 14T)
The Torque 2812T/720 -also has stator diam of 30mm, but with 25mm length; It has 12 wire turns, Kv of 720, and aheavier weight of ~177g, external diam of 35mm and length of 48mm (its stator size is 30mm diam, 25mm length -same as a "3025" motor on stator-size) (its external size is ~35mm diam, ~48mm long -same as a "3548" motor on external dimension). ( -It is the exact same motor as: Hacker A30-12 XL V2, Kv 700; LiPolice /OKHobby Infinite/ Foxy 3025-770Kv 12T; andTurnigy SK3 3548-700kv, 12T ).

8. PJS MOTOR NAMING SYSTEM
PJS brushless outrunner motors are named very simply, according to the amount of static thrust that they are capable of producing. Of course, in practise the amount of thrust depends critically on the prop used, and number of Li-Po's used -so it is not necessarily a useful or accurate naming system.
e.g. The PJS 3D 300 SFR motor, is for indoor models. It produces 300g of static thrust; It is heavy by the standards of today -weight 36.5g; Kv 1210; external diam 32, length 45mm.
The PJS 3D 1500 motor, is for park flyers. It produces 1500g of static thrust; Weight 131g; Kv 765; external diam 40, length 45mm.
The PJS 3D 3000 motor, is suitable for 50-size models e.g. the Sebart Angel 50. It produces 3000g of static thrust; Weight 345g; Kv 496; external diam 53, length 46mm.
PJS produce a very large range of motors, from small 36g motors -up to very large 1,550g monster motors using 30 inch props which produce up to 18kg static thrust - see http://www.pjs.cz/index.php?cPath=1&...=2a&page=1

9. MEGA MOTOR NAMING SYSTEM
Mega outrunner motors have a naming system which is a little different to others. Some motors are named with reference to the older brushed motors. Other larger motors are named with reference to stator size and number of turns.
e.g. The Mega RC 600/10/8 motor: is equivalent to a 600-size brushed motor; the 2nd number "10" shows a stator length of 10mm, the 3rd number "8" shows it has 8 turns. Weight 85g, Kv 1695, diam 36mm, length 35mm (its stator size will be 30mm diam, 10mm length -same as a "3010" motor on stator-size) (its external size is ~36mm diam, ~35mm long -same as a "3536" motor on external dimension).
The Mega RC 41/30/15 motor: 1st number shows stator diam 41mm; 2nd number "30" shows a stator length of 30mm, the 3rd number "15" shows it has 15 turns. Weight 499g, Kv 410, diam 49.3mm, length 52mm (its stator size is 41mm diam, 30mm length -same as a "4130" motor, or ~4030, on stator-size) (its external size is ~50mm diam, ~52mm long -same as a "5052" or a ~"5055" motor on external dimension).

10. MVVS MOTOR NAMING SYSTEM 
MVVS uses a different motor naming system to that of any other company. Each outrunner motor is designated with a 1st single number, signfying size of the stator, and the Kv. A list of the motor numbers is shown below, showing the stator size that this number refers to.
e.g. The MVVS 2,0/1120 has a stator diam 26mm, length 9mm, and Kv 1120. Weight 87g, external diam 36mm, length 31mm (-same as a "2609" motor on stator-size) (-same as a "3630" motor on external dimension).
The MVVS 8.0/680 has a stator diam 36mm, length 20mm, and Kv 680. Weight 223g, external diam 44mm, length 46mm (-same as a "3620" motor on stator-size) (-same as a "4446" or ~"4250" motor on external dimension).
For MVVS motors:
