Default RE: Which chinese factories make various brushless motor brands?



ORIGINAL: rosnik About Motrolfly motors the interesting thing , getting them in ..comparison .. to all standard B/less motors,
is exactly the fact that they got larger diameter and the shorter in length rotors.
This .. improve torque and one bit penalize consumption. More torque , mean that Motrolfly motors can flip larger props.

Worth noting: Torque 4016T/500 (280g) is EXACT SAME motor as: Hacker A40-10 L V2, Kv 500, 10T =Turnigy SK3 4250-500kv, 10T =PA Thrust 50, 487Kvsee: http://www.rcuniverse.com/forum/fb.asp?m=11428699



-Above RCG thread says: Motrolflys are extremely popular
many run the Motrolfly 4315-480Kv with 16" props.
The Motrolfly runs very cool compared to others
These Hacker and Torque motors are often used with 14", 15" props -however they have a higher Kv.
The Hacker A40-14 L , Kv 355, 14T -has a lower Kv, and will swing a larger prop ...

-Hacker is a good motor, but they like Motrolfly better (this link name, which is blocked by RCU -is FG )

AS FAR AS MOTOR TORQUE IS CONCERNED:
Hacker publicity / marketing / hot airALWAYS states:
"... The Hacker ... A- *** ... ... This 14 pole, Outrunner design creates MASSIVE TORQUE, therefore larger direct drive props can be used without the need for a gearbox ..."
e.g. https://www.aero-model.com/8_67_887/...-10L%20V2.html



-Perhaps Hacker motors really WOULD create "MASSIVE TORQUE"-if they had a design like Motrolfly, with a larger diam and shorter length stator ...
