hi to members

plz help me yaar, i have moss with A 2212 / 1000 kv, battery is 1000 mAH/11.1V, 20 amp ESC, futaba 6EXAP with R146iP receiver

when the battery is connected to ESC the Beep sound comes from motor 

i m not gatting the point that why the beep sound comes from motor?

i have changed all the setup even the motor was canged but the same result

guys i have gone mad 

can any help me plz 

nehu

Hey can you post some pics of the motor and the ESC.
And make sure what's beeping, motor/ESC? 

Hi Nebutech

You have to set your throttle to idle when you connect your battery to your esc. Even if you have a little throttle up, the esc will just enter into programming mode. If you have a throttle trim, trim it all the way down. Did my suggestion work?

Since you mentioned that you are using a Futaba 6EXAP, the first thing you want to verify is that you have set channel 3 (throttle) to "reverse" in the "REVR" menu.

Otherwise, the ESC would detect it as full throttle (even though the throttle stick is at the lowest position), and the ESC would either refuse to arm or go into programming mode (depending on the ESC brand/model).

hi

jerryazhakathu:-    as u said yes the throtter is at idle speed

me-my-parts :- as i said the MOTOR is Beeping in a code style like some type of signal .  sorry for the pic dude my cam is not working.

anwarbhai :- yes i have set the channel 3 (throtter) at reverse

but as i said same result the MOTOR beeps

setup is
motor is RCFORALL A2212/12 1000kv
ESC is dys 20 amp

thanks to all for ur reply

Never heard of "beeps" coming from the motor. 

Do you mean some kind of "whirring sound" from the motor, or actual "beeps" that are possibly coming from the ESC ?  You have to confirm the source of the sound before any resolution can be arrived at.

the beep sound is coming the motor because the ESC is sending programming signals to the motor(I havent seen any airplane ESC's making any kinda beeps or sounds by it self)... I have had the same issue with a 50A HK ESC because there was no BEC. It stopped beeping once I added a BEC.

I don't understand how  a motor can make beeps But an ESC could make beeps because it could have a micro speaker in its circuitry to assist the user when programming the ESC by giving audible confirmation.

Hello Mr. Rao

Try feeling the motor while beeping or hold the motor close to you. Motor works as a buzzer. I am surprised many of the people didnt know about this. If you look at the below manual and many of the manuals, you can see it says, "hear a beep from the motor".

Look at " How to use your new ESC" section in the below manual
"

www.fmadirect.com/support_docs/item_1268.pdf

 The throttle channel on the Tx  could be  in reverse .
ESC's  will not allow a motor to start when the  throttle channel is on reverse.
So this is warning that the throttle is on reverse.

Be careful  to ensure min throttle when you reverse the  the channel on the Tx  otherwise you would have the motor on full throttle when you reverse the channel.

and please follow this  RESET/ START UP procedure  to ensure right minimum and maximum  settings.

You are right, I stand corrected.  I am also surprised that I never looked at it from this angle so far, even though I have held the motor sometimes when it being armed, but did not feel it as the buzzer. Since I have heard even elaborate "tunes" (like old songs) while using some brands of ESCs, I was under the impression that the tones are made by a small buzzer on the ESC itself.

BTW, there is no reference like "hear a beep FROM THE MOTOR" in the manual you posted, or the various ones I have come across so far.  That easily added to the misunderstanding.

Nehu -

As I suggested earlier, and as Sai is suggesting now, it sounds like a case of the ESC detecting high throttle when it is powered up.  Although you said you have reversed channel "3", there seems to be something simple that you are missing. So confirm the following also.

1.  Make sure there is no "trim" and "digital trim" on the throttle channel.  To be sure, try clearing the model in the transmitter, or try doing the setup on another "clean" model selection.

2.  Make sure your connections are correct. The throttle should be on channel 3 (it is easy to notice on the R146ip where the channels are numbered), and make sure the connector is not reversed (the signal wire, which is the "lightest colored wire, usually white", should be towards the middle of the receiver, ie, towards the printed number "3")

3.  Make sure your throttle is at idle speed / lowest position.

Have you tried whether the motor works after the beeps??

The motor gives a confirmation tone stating that everything is connected properly and that it is armed and ready to go!! You are probably referring to those beeps..

Sorry, Jerry. But the motor CANNOT "beep". It is from the ESC, for certain. If you have read the above in a manual, it is very likely an error due to  poor translation.

OK... that makes me feel not alone, yet confused 

See the "crude speaker" reference in this thread : http://www.wattflyer.com/forums/showthread.php?t=22370

There are many such references elsewhere, like :

I am trying to rack my brain as to how it could be physically possible for a motor to generate "beeps". A buzz maybe.

Beeps are single tones. To generate such sound you need some sort of diaphragm to move "air". The only "movable" part in a motor is the rotor. Beats me how that could do this.

I guess "a beep is just a well behaved buzz"    Sorry, I couldn't help make that comment

Very clearly states that all Castle Creations Speed controllers feature: "AUDIBLE ARMING SIGNAL" (amongst others).

Still inconclusive as to what really generates the tone/beep/buzz 

This *could* also mean that the ESC generates the signal that causes the motor to "emit" the sound !

May be this is the clincher

"It is in fact the motor coil oscillating that you can hear."

Yep, I am a total convert !

http://www2.wattflyer.com/forums/showthread.php?t=11584  (the whole thread is about this)

Anyways, yet another thing learnt on the forum

And for Nehu, it looks like he mistook the initial beeps of the ESC/motor as a "problem", while it is normal and to be ignored.  There is no mention by him that the beeps are continuous, and we all ignored the "elementary, Watson" part

In an outer runner motor the coils cannot and do not move. Wonder how they "oscillate"?

I would like to clarify that I admit that I could be wrong, but there seems no logical explanation yet offered for it.

Maybe I will try and obtain a dud ESC and dissect it for research !

Judging by the last link from wattflyer.com (and the links from there), I think there is a lot more to how sound can be generated than the diaphragm method we are all familiar with.

And I felt the same initially, total disbelief and surprise at how something so close to home was totally missed !

thanks to all

anwarbhai as jerryazhakathu  provided the .pdf file for the beep sound generated by motor is of programming the ESC

i got the point that the beep is of ESC for programming it.

thanks to all

i m happy that my Tx and Rx is ok thanks to u all and god

and special thanks to jerryazhakathu

now i m trying to program the ESC

Sushil bhai - Looks like me, you and a whole bunch of other people are surprised with this.

Here is Castle Creations themselves being more specific about who makes the beep. On the second page of the document below, they say "The Phoenix will beep the motor to indicate that it is armed".  There is a similar reference in page 3 also.
