Turnigy Aerodrive SK3 - 6354-245kv Brushless Outrunner Motor
Turnigy SK3 Motors are the next leap forward in motor quality and design. We instructed the engineers to source the best quality magnets, bearings and materials available to them and develop a motor that would not only rival, but surpass the quality of many leading motor manufactures on the market today.
The result is an efficient, high caliber motor using quality double shielded bearings, sintered Neodymium magnets and a string wound stator ensuring an accurate and consistent winding each and every time.
The Turnigy SK3 motors are suited to modelers who are seeking a quality brushless motor without compromise.
I've bougth this motor since few months ago, never use it, only a test on bench, with good results, yesterday was the first day at field with the my new plane, unfortunately the motor back home with magnets unglued, and bearing hearing bad, so i think that it's garbage engine. I'll try to repair but with AXI motor never had passed. Finally lower price same to lower quality.!! This is my experience. Thanks to all
I have big problems with this engine in usage with Superbrian 100A on 8S Lipo Akku with 2blade 22" x 12" or 20"x12"
By the first test mode the engine destroyed itself by seperating the magnets. After repair i started additional test modes with an other ESC Setup, unfortunately without success.
Ich habe große Probleme mit diesen Motor in Verwendung mit Superbrain 100 A an 8S Lipo Akku mit 2blade 22" x 12" oder 20" x 12"
http://www.hobbyking.com/hobbyking/store/images/ em_cry.gifDer Motor hat sich beim ersten Testlauf von selbst zershttp://www.hobbyking.com/hobbyking/store/images/ em_cry.giftört indem sich die Magneten gelöst haben.
Nach der Reparatur erfolgten weiter Testläufe mit anderem ESC Setup, aber leider ohne Erfolg.http://www.hobbyking.com/hobbyking/store/imag es/em_cry.gif
How can i calculate the turningmoment in NewtonMeters for this Motor?
Kown is the radius from the shaft with 4mm and the Max. Input Power of around 2kW.
But this is not the Power on the driveshaft.
So what do you think, how can i calculate the turningmoment ?
I need an 250Kv motor to power my P-40 1700m and 250Kv are hard to find in 50mm motors.I know it will be needed some surgery in the "motor room" but it will work. I ask if, due to timing and other factor it can be run om 6S.I think yes.Does anybody has experiency on this configuration to clear the doughts?
Help well come.
Yes this motor can run on 6S. However prop size will be very large (over 18" diameter for a 2blade) and efficiency may be slightly lower. I doubt such a large prop would fit, even if a 4blade prop is chosen. Secondary a high pitched prop would be required to reach sufficient pitch-speed for comfortable flying (for instance a 19x16 2blade minimum). A motor with a kv of ~400kv should me more suitable, depending on the max prop size you can use.
Tks, Gerben, I got some experiency with props and as far as my accuracy goes, the original prop for this p-40 is 16,5 x 17 x 3 and this motor will fit ok with good eff. The fell the motor will run 1/2 power, good for efficiency. I'll pay 3.5 Oz, 100g pennalty only.
My motor 6354-245Kv arrived and I got: Stator diam = 50mm, height 20mm, idlle current 1.42A at 11.23V, resistence 36 mOhm, 28.6 percent more than advised.
Runs very smooth and looks sound. 12 tooth 14 mags. I was looking for a motor this size but 18 tooth 20 mags.
Chister, this motor should be able to fly a 7kg model comfortably. Which motor is "best" is depends on the type of model/flying (a Piper Cub needs a different drive compared to a Mustang) and the max prop size the model will allow. For this motor on 10S expext a prop of about 17x10 (depending on batteries and specific lipo, always measure your drive system prior to flying with a Watt-Meter).
I bougth this motor since few months ago, and until today hasnot fixed to none plane, but I've made a bench test, to know how many Amps it eat, so with a APC e20X13, it need abt 55 amps, with and APC 18x8 it taken 43 Amps, on full. May be this information will help you.
