is this a two pole brushless? I purchased three of these to build my tricopter and three of the turnigy 20 amp esc's and am having a power issue. are these incompatBle? using a kkmulticopter v5.5 board flashed tricopter 2.3.
i appreciate the feedback buck not getting power to the board when i dont have any props on it to begin with i dont think that would matter. I think the turnigy 20 amp esc only work with two pole motors and best i can tell these which are wound over 12 magnets are either 6 or 4 pole so there is no power loop back to the board that and they all have bec' on each esc so no good but thanks for trying to help. appreciate it....
a 2 pole motor works the same as a 22 pole, a 4 pole, 6pole, ect...
It just means it has more than what is needed if it is more than 2 poles. If it was the amount of poles that was causing your problem it would mean you have a defective motor
I am trying to lift off my UAV with 7.4V and its weighs about 1 kg.. only a slight displacement is observed at full throttle. Do i need to vhange the voltage to 11.1V?
Hey prashanth, im sorry to burst your bubble. But you have chosen the wrong motor entirely. This motor is not capable of such high thrust. Even on 3 cells lipo it wont be enough. For that kind of weight of a plane , and if you want to run 2 cell lipo. I reccomend a high KV motor, such as the Turnigy 4400 kv 450 heli brushless motor. With a good 55 ampESC such as the turnigy 55 amp trust ESC. And a high C discharge lipo, such as Turnigy Nano Tech 25- 50 C 2 cell lipo. And a 7X5 APC prop. Trust me, this setup is light weight and will get you the thrust to fly comfortably. Hope this helps Buddy.
Bought 4 of these motors recently. Have yet to run them, but I would like to point out that 3 out of the 4 we bought do NOT have symmetric mounting holes. This lead to the motors not lining up with their frames. Picture: *******bit.ly/11VTIBG
Can't comment on the quality of the motors in action, but 3/4 is not a good ratio...
Pls help me ı* m new in this job.my question is: ı* have an project a 700 gram cylindirical payload must descent the ground under 10 m/s velocity.ı* have to use two propeller which rotate the opposite sides.which motors and accesories ı* should use.
Good motor for a good price. * Shane they should have came with two. Also just so you all know a motor mount that's compatible for this motor and is sold on this site is
Alloy BL Motor Mount for 28mm Motor (2pcs/set)
Remember to get the propeller adaptor
Hope this helps
yeah thats another thing i was worrying about, how to attach the propellers. at the moment ive just jammed them on there(they fit prity tight) so i hope they stay on. how are you suppose to attach them??
I have this motors (4 for Quadrocopter) and 4 speed contollers (30A BlueSeries Brushless Speed Controller). Can I use 12V from power supply unit or I must use 11.1V only from this power?
No-load current is 0.55A at 7.4 volts. Just measured it using multimeter.
Nothing except for motor is supplied. Still, the quality is good. Not muh vepoxy around magnets, but they are fixed in slots in aluminium cap anyways.
Thrust is completely dependent on which propeller you use. But here are some equations that should help: Power=Current(A)*Voltage(V) and Power = Thrust*Velocity so if it is being used on an airplane and you know the speed you are flying at, and the power you used, you can back out the thrust.
i have a question for you...this motor has something to fit on the frame...like prop adapter or that plate which make the connection between engine and frame...or i need to buy all this staffs?
Hello,
I just finished building a hex with these 2725 motors and they work just fine. I was a little put off by the motor wire diameter, but the overall build quality is good considering the price. 2 out of 6 motors have noisy bearings, and one motor was missing the retaining clip that keeps the housing in place. I am running 8x4.5 props and hobbywing pentium 18A ESCs. It will hover at just under 1/2 throttle. It weights 1,806 grams with all FPV equipment on board. I have not had a chance to put the watt meter on the unit, but I hope to do so soon. Safe flight time is about three minutes and a few seconds on a 2200mAh 3S, or longer without the FPV weight.
Yes,this should be fine,the Plush 18amp can handle bursts of up to 22amps so if you are close to the 17amp limit on start up it may go over for a brief time but will then settle down to within limits.
I have a quad frame,measures about 2ft. across. What motors would work well with this.Should all motors rotate same direction or 2 one way, 2 the other, probably dumb question, but new to this hobby. Thanks
sorry bud but you are wrong. I suppose using a multirotor you could put a motor on each side but this would only make it the same as having a 4 bladed prop on your motor and therefore less stable. usually having more props will make a multirotor more stable, but this rule only works if each prop is driven by its own independent and stabilized motor.
The double motor mount on quad is great if upper motor and lower motor of the same arm are set in counter rotating mode. This configuration is perfect to cancel gyroscopic torque during motors acceleration. this give more stability.
The Chinese let the costumer beta test their products. Any day now, someone will chime in with what props/battery combinations will produce the best thrust/current draw. I was going to order 4 of them, but I decided to wait until we get real numbers on performance.
BOUGHT 4 OF THESE MOTORS 1 KEPT ON STOPPING THOUGHT IT WAS THE ESC BUT NO PUT THE MOTOR UNDER LOAD BY ITS SELF NOW IT DOES NOT GO AT ALL. WIRING IS POOR ONLY 3 WIRES PER LEAD ? JUST HOLDS SOLDER
Tried out HKs warranty I have no answer after three weeks . I think the problem is they don't know the difference between Platinum and lead started buying from E bay again even the little Guys there know they have to look after there good customers ?After hundreds of orders and thousands of Dollars your just one of the mob.
I also bought 4 motors and 1 kept stopping. It turns out that I didn't notice that one of them was a 1000KV until after the motor burned up!!! Someone who filled my order SCEWED up and put the wrong motor in!

Very nice motor although I couldn't slide the shaft through without fear of damaging it. It would need a thin firewall for attaching it behind the propeller.
