Hobbyking 3A Single Cell ESC - Brushed Micro Motors
The Hobbyking 3A Single Cell Brushed Motor Speed Controller is designed for single lithium battery driven micro RC model applications. It is extremely light and is the perfect choice for indoor ultra micro airplane and helicopters. Due to the continuous 3A current capability, it is the perfect choice of wide range brushed motors. The ESC also features built in battery low voltage cut-off and high throttle start up protection, to ensure the safe operation. There is no integrated BEC circuit as this ESC works with a single cell Lipoly, RX power is therefore supplied at 1s voltage.
Specifications: Net Weight: 0.4g Weight with wires: 1.6g Dimensions: 11.5 x 8.6 x 4mm Voltage Range: 2.6~5.5v Low Voltage Cut Off: 2.75v Max Continous Current: 3A Max Surge Current: 5A (3 seconds)
I just thought of something else: Does this ESC support reverse ??? O.o I'm planning to make a micro scale RC car, and I'm looking for a small brushed ESC.
Hobbyking 3A Single Cell Brushed Motor Speed Controller - what are the three types of connector used by this ESC - is there a battery in the Hobbyking range that plugs directly into it?
thanks.
Help! Too many choices. I am new to car ESCs so don't know which one to choose. I have a motorized platform with 24V 2A motors (pretty sure they are brushless). What do I need to control them and which program card? Thank you in advance.
Thanks Arun but I am pretty sure the motors are brushless and I was told not to use a brushed ESC. Also, the voltage has to be 6C for closer to the 24V range. All the ESC I have found so far are 2C or 3C.
2 connectors only. They look to be ordinary DC motors in a sealed shell. I am looking to operate them forward and reverse so was told to go with a car ESC. Problem is they are 24 V motors and running them at 12V or less does not work well.
Richard as they are 24v motor you can go with a 4-6 supportable brushed esc and make a try with a 6s cell or with two 3s cell..
Better option will be choosing a brushless motor and esc from here, will be under budget and powerfull than your brushed.
Hope this helped
Arun, that IS what I am trying to find out ... WHICH ESC will handle 24V. The website does not seem to be able to let me search for that so I am asking anyone with experience with these products to identify a specific ESC that I can use.
Do you know which ESC will handle 24V ?
Hi Richard, mostly all Power Mosfets cant handle that high voltage, but i.e. IRL2203N will do. If you can read german somehow, search for nessel electronic : togro brushed esc kit. But thats not cheap but well known german quality.
Sorry to say that Hk dosn't sell any brushed esc which can handle 24V..
The one you can do is Check any other website for a 6s capable brushed esc. If you want to make your own one..
give you your mail id will mail you some details.
Michael I dont think all mosfets can handle 24v..
Every mosfets has its own capacity, If so why we need different valued esc's? one is enough na? and And even though if the mosfets are capable of taking a 24v it cant Raise to the max current the motor can produce thus it will get fried.. :)
What is the proper receiver to use with this or the gp-6 combo micro motor. I understand that the regular 6 ch receiver weighting 35 grams isn't a good idea. Does HK há*s a receiver to work with these micro systems ?
So if you move your stick from zero throttle to max instantly, the motor takes less then half a second to reach full speed? I have some brushless ESCs here and the spinup time is atrociously bad.
Do these have a fast response time to throttle? I have had a few small ESCs that unfortunately have a ridiculously slow spin-up time. I need a fast ESC for a micro quad.
fast enough to not notice any lag on my micros. i can verify that they will run at 3A. (twin PZ p51 with GWS5030, 1.4A draw each)
these will last a very long time.
I understand ESC has a Molex 1.25 servo connector to the RX, but it's not clear to me which connectors are used for the battery and motor. Can anyone provide details or post link to adapters? Many thanks.
this plugs right in to the R415 and there is a 'jst to 1.25' adaptor to go from a 'standard' 2.54mm pitch to this plug in the servos and parts catagory.
It should work with any receiver that has a Molex 1.25 servo connector. If you don't mind splicing or soldering, you could certainly get it to work with any receiver. Or, if you are trying to get this to work with a receiver that has JR connectors, you can get an adapter plug to do the trick right here www.link
Hi, I need small micro BRUSHED ESC for toys, but with REVERSE (CAR/tank/construction vehicles... perhaps micro boats).. I see none at all. Does it exist? Perhaps, would HobbyKing offer at least some?
does not exist, yet.
best bet is to get a standard size analog servo and use as Dbacon says. i have done this for micro boats using HXT900 servo (slow putt putt boats)
HEY DBACON,
Servo boards dont work - they wont push past 1.5 continueous! tried servos from 1.9g to 30g servo. SERVO BOARDS DO NOT WORK AS ESC. Extensive testing....
Also mosfets are not cheap, available or easy to come by locally! the smallest mosfets here locally cost 17.95!!!! Not worth it to make your own out of servo boards!
Would a three motor set-up conected to one ESC work,as long as combined amp draw didn't exceed ESC's limits? Motors are wired in parallel and one has polarity reversed for counter rotation.
Yes, it will work as long as you wire everything correctly and the combined amp draw doesn't exeed the ESC's limit. You will need a bigger battery though because you have three motors insted of one.
Follow-up to question on 1/05/12: Could the problem be with the high throttle start up protection of this esc and I'm not getting it "bound" properly.My Tx is old but works with my other planes.
Using this esc with ZX Technology R4J Rx/Futaba Skyport6 Tx and lazystik's wiring dicription. The servos work fine but no throttle or sometimes motors go to full speed when bat is connected.
yes, ive dont this many times. you need the right plug, or you could cut off esc motor plug and motor plug, twist together and hold in place with heat shrink tubing. no soldering. as long as you secure the wires, should never come loose. (i do this alot, never had a failure)
This is a joke guys... Strip apart a 2 dollar micro servo and take the motor control unit, desolder or use the motor in the servo and run that as your ESC. Put the servo motor on the throttle channel and trim the channel so it's 128-255 in its pulses so that motor spins one way.
Or you can solder a fixed 100k or 10k resistor depending on the original servo pot values. Then you have a fixed 0-100% using the servo motor controllers as your ESC. Don't be wasting your 10 bucks. Just my twin cents.
Don't worry bro, DIY is Learn by trial process... Yeah I tested this today and I didn't even needed to solder a resistor, just simply short the pot wires (2 out of the three) and your gold. Yeah the gear box and motor with the prop and this ESC which sells for 24 bucks is not worth it... IMO the parts together should only cost 5 bucks. Servo, motor and gearbox. Anyways it isnt even that powerful. 12-18 grams of thrust. We're talking minuscule negligible.
i have not used every servo, but i have use 10 gram servo as ESC, and they suck for planes. the throtttle is too choppy.
this unit probly only has 200 step resolution, but feels very smooth in the air.
its a very good product and will last a long time
Hi The General. I have tested many servo boards as speed controllers and it works just barely and in very limited applications. You need a 20g plus servo board to run a single 6mm gb. Can't imagine what size board you'd need to run a 8.5mm gb! 9g servo boards wont push your 6mm micro motors to potential. Better for led or actuators, but for running coreless motors its not a good option.
SERVO BOARDS AS ESC DONT WORK. 1S it wont push past 1.5a ~ 2s you will fry the boards even on 3s rated boards. Dont multiple boards none work like a regular esc!
After reading lazystik's response, is he right by saying that the thicker black and red wires on the end of the ESC are the ones that go to the motor? If so that would explain why my motor runs constantly and uncontrolably. the connector on the other end fits the 1s lipo's perfectly. why would hobbyking produce something so confusing?
I also wonder why would someone does something such confusing but for those who are planning to buy this controller I confirm the wiring as described by lazystick. I have just completed re-soldering of the connectors and it works! Hooray
Thank you lazystick
What type of plugs are on this? I am guessing the battery plug is the same as on the small 1s cells such as the Turnigy nanotech 160mAh, but what type is the plug that goes to the receiver? Is it compatible with the 1.25 Molex on the new HK Micro DSM2 receiver? HK, how about being specific about plugs on any such items as this? Photos are not really enough, as a lot of the plugs look similar.
This is a esc for brushed motors using a 1S lipo battery. The black, red & white wires are to your throttle channel. On the same end of the pc board are a heavy red & black wire going to your lipo. On the other end of the pc board are 2 thinner red & black wires going to your brushed motor.
Gracias hermano, me sacaste un gran dolor de cabeza.
Yo tambien comore ese ESC y no logre hacerlo funcionar. Gracias a tu comentario, logre que funcione, es cierto lo que dijeron que es confuso.
Yo compre el combo(motor, ESC y beteria) y la ficha que debe ir al motor coincide con la batria.
Gracias otra vez.
Saludos-
I have tryed, does work perfectly. Wiring as following: wires on the left - to motor tick wires on the right - battery three together wires - to receiver: black is negative, red is positive, orange is control. Thick wires I have unsoldered - obsolete: Power comes from receiver.
I use with HK-6DF with respective receiver. It starts almost at full throttle and cannot rev it down. Any ideas what the problem is? Any manuals for this?
Not worth the price...Why? It's just an esc no ubec or anything.... For like almost 10 bucks? I desoldered the wires it came with cuz they useless and I don't use them plugs...

Have a few of these, using with GPS-6, GPS-7 and GPS-8 motor gearbox setups, very smooth control. It would be nice if there was just bare wire for the battery connectors though, the connector supplied is useless and I just cut them off.
