Got an old brushed motor laying around and want to put it to good use? The Turnigy brushed ESC is an excellent speed controller with a linear throttle curve, Lipoly/NiMh ready and programmable braking.
The break function can be turn on/off by the jumper
Battery type can be chosen by a jumper
For Lipo the threshold for each cell is 3.0v, less than the threshold ESC will gradually reduce the output power
PWM frequency is 2KHz
Over heat protection over 110C
Throttle signal loss for 1sec will gradually reduce the output power, after 2sec completely cut-off
Hi Arlindo. The actual difference exactly is that this ESC is for old brushed motors. The function is entirely the same but the design is different.
You can actually use this on Cars/Boats and rc planes that still uses brushed motors.
Yes, but depending on the turns of the motor you will be using, and depending on what type of connection.
1: If you plan to connect in parallel I strongly suggest to use only 2X 540 size motor * 27turns each but not lower than a 23turn motor. In parallel connection, the motors will run FASTER but battery will last SHORTER than a single motor.
2: If you plan to connect the motors in SERIES, you can run as low as a 19turns each motor and maybe 4 motors at maximum. In series connection motors will run SLOWER and battery last the same as a single motor.
Dongskie Hello, thank you very much, very kind! But I did not understand what you mean for 27 turns 23 turns etc.. I have many types of brushed motors taken from helicopters. Is there a way to calculate the amps to the motors? thanks
Hi Nicola: Turns in a motor refers to the windings inside the armature, or the gold wires you can see inside the spinning part.
What type/size of motor do you plan to use this ESC? Give me at least a size so we can approximate.
Dongskie Hello, here are the measures of the engines that I have: - 27 mm x 15 mm x 20 mm has not the round section but two flat faces. - 25 mm x 32 mm round - 32 mm x 24 mm - 32 mm x 15 mm x 20 mm has not the round section but two flat faces. - 37 mm x 27 mm. I wanted to ask one more thing kindly, you can use v-tail system of two motors to vary the speed with two esc? So, instead of connect 2 servos, connect two motors, type coaxial helicopter or boat. thanks for your time! greetings nik
The motor sizes you mentioned are relatively small and are easily handled by this ESC, I don't see any issues will arise if ever you run 2-4 motors in parallel, more so in series. With regards to your question, Yes, but I think you will need to connect the 2 ESC on different channels to control then independently of use the Transmitter's Mix properties to control them at the same time.
Dongskie Hello, I asked if I could connect 2 motors device for V-TAIL against rotating coaxial helicopter, to give the sense of right and left, that helicopter turn on itself to variations of the two RPMs. Or boat with 2 motors to turn to the right and left, Peer example, you can do with v-tail? thanks P.S. then you can connect 4 small motors on 20A esc? or even larger? thanks, you're very kind
Dongskie, one last thing. based on your experience what do you think would be better concerning to use and future application to buy a mode1 or mode 2 transmitter. i initially have chosen a mode 1 but now i think of the option of mode2. i would appreciate if you provide me any help on that/your opinion. thank you
Mode 1 Throttle at right stick / Mode 2 Throttle at left stick. Well it really depends where you find it convenient for you, I for example have been used to Mode 2 Throttle at Left Stick during my 2 channel car days and have grown accustomed to it, if I were to use a Mode 1 I would probably crash my car or plane LOL. Long ago Mode 1 was issued in USA and Mode 2 was issued to Asian Countries and now both are offered worldwide.
Dongkie: i am thinking of purchasing this ESC and the HK 2.4 6chv2 radio system along with couple of servos. since you know the battery i am using and the motor i was wondering if they are gonna work all together. but i think they right?
Hi DOngskie, since i am new in RC modelling i am curious about a few things i hope you might help me.
first escs work as digital potentiometers right? and the 3 colored wire (BEC mode) is used to power up the receiver and the servos i am connecting to it right? and the one of those three cables is the logic to trigger the ESC (potentiometer) like how servos work. right? therefore, assuming all the above i plug my motor to the esc, the esc to reciever and all motors to reciever and my model boat will work assuming again that the reciever and servos work at 5Volt minimum and all together do not draw more that 1Amp current???
Hi Chris! I don't know how to explain it exactly but yes it works like how a potentiometer works, but not exactly lowering the voltage. * This is how I understand how an ESC works, the voltage is intermittently applied to the motor like a pulse, pulse speed is varied via PWM frequency or Pulse Width Modulation frequency. If I am correct, the PWM freq is very high at low speeds thus you hear a whining noise in the motor when you start it because the voltage is cut at very high rate, then the PWN becomes low at high speed and delivers an almost single pulse giving the full voltage and full speed.
The BEC is entirely independent from the motor AMP rating, the BEC provides constant voltage and amperage to your RX and servos, the quantity and size of servo can affect your BEC's performance, over demand can cause your ESC to lose power or "brownouts".
Quote: "and all motors to reciever and my model boat will work" - I assume you meant Motors to ESC??
first take out the prop.
1. Connect the ESC to the throttle channel of the receiver.
2. put the throttle stick to maximum position, Turn on the TX
3. Now connect the ESC to the battery
4. Now throttle stick to minimum position.
This should calibate throttle end point.
It worked here.
Thomas, I've tested it so far on my car with the engine off and was reading 13.3 volts and it hasn't burned out yet. After I get the circuit bugs worked out I'll put it through the paces with the engine running and approx 14.6 volts and we'll see how it goes.
No, cutoff will take effect when the battery voltage reaches 9v it doesn't measure each cells voltage individually. the combined voltage of your example is 9.3v so in this case your battery would be damaged.
I think it would - from what I could figure out, without knowing exactly which motor you are using, the 600 motor would draw at a maximum 28A. You wouldn't be running it at that current all the time, so I would consider it inside of the burst envelope.
I just ordered one of these to drive a 12 volt 10 amp pump in an automotive application (my real car not an r/c car). Cars sometimes see as much as 14.5 volts peak when the alternator is running and charging. Will this burn up this unit or will it be ok?
It would be difficult to know without knowing exactly which components are on the circuit board. A fully charged 3S lipo would be 12.6V, and 10S NiMH could have a terminal voltage of 15.0V fully charged - I would suspect that there would be some safety margin built into the components they are using, and it would likely work.
it has no reverse, but i use it in a car and it works just fine
39 thumbs up!
Compre 4 de estos, los 4 funcionan muy bien, son mas pequeos de lo que me esperaba lo cual esta muy bien ya que use uno de ellos en un Striker y no hay mucho espacio, la respuesta de estos esc es muy buena y del precio, pues simplemente insuperable...

great little piece of kit at a price that you cant say no to, I connected this to a hot can motor and ran it up to a 30amp draw for 5 mins and it didnt even get warm, Im very impressed at this price

I am very satisfied with this speed controller, very good quality for small price. I give 5 stars!!

Most of my planes are actually brushless however, recently I decided to use stock can motors for a project. Of course, I needed a speed controller for brushed motors so I went looking around for a decent ESC around 30A. I happened to visit HobbyCity and found the Eagle 30A Brushed ESC and figured for the price, it is defiantly worth trying. My gamble paid off big dividends as the speed controller works great! Wish I had purchased most of my electronics from HC.

Excelent product for the price...just $7.5
It comes with the option to turn break on and off with just a jumper. Also suitable for Nimh and Lipo with also just a jumper.
My Super-Cub motor is pulling only 16amps so can't test the limits to the rated 30amps.
