Hi Guys,
 I have a Turnigy Bell 2409 1600 KV motor and HK 25A ESC. Two month ago when i bought the motor and ESC, when I connect them and connect the battery,the motor produced a loud long beep and started to work.But few days ago when I connected the ESC to the motor and connected the battery, no beep was produced and also the ESC was getting very hot after few seconds.But when I go close to the motor some beep sounds were heard.But the motor didn't work at all. :banghead: So please help me :help:

Have you tried a different motor with this esc?
Are you able to rotate the motor shaft with hand, i mean is it free?

Yes. The shaft is free.

Check if the wiring of motor is all right. 3 wires which come out of coiling of motor sometime break down due to stretching of wire. In this case motor sometimes make little sound but doesn't work.

They are all right.

Try different ESC and motor combination.
Then we can see if problem is in motor or ESC.

I dont have more ESC or motor

Please help

Try setting throttle range for ESC. It works for me sometime when motor is not responding

The ESC is not programmable

Where did you buy ESC? Can you post the link?

You should be able to set throttle range with this ESC. Read the reviews of this ESC on above link. Procedure is given there. Give it a try.

Thanks a lot Spitfire.I will try and tell you later

Another problem after throttle ranging.

Also the motor and ESC gets hot.
Please help :help: :help: :help: :help:

please

If your motor and ESC are good then this can happen because of three reasons:
Lose connection/solder between motor and esc.
Wires/connectors on the motor are getting short.
Something stuck in the motor.

1. How have you soldered the bullet connectors? Have you removed the coating(golden coating) of the wires and then connected ?
2. Heatshring usually hides if there is loose soldering, just remove the heatshrink and check again.

Connections are OK

How are you sure about that, put up some details? Seeing that video of yours every one is going to ask you this question.

I have just now opwned the heat shrink and saw.

do u notice your bullet connectors also ...they are exposed and have high chances of getting short any burning your esc....you have to insulate they using heat shrink tube ..never leave them exposed

ok

 :o Not good!
Ved be very careful, dont leave any connections open. This is very dangerous, ESC's and batteries burn like diwali fireworks, Annar to be specific.

Wonder if the damage due to short circuit is already done :(  It was a bad idea to leave connectors like that, at least a layer of any type of tape would have afforded some protection.

While taking the video,I have covered them with a cello tape.

may be the esc is short circut already , try another

I still feel that one of your connection to the motor is bad.
Do this; take out one motor connector and try again, if motor stops moving then re connect and take out other connector. Out of the three there will be one connector which will have no effect when disconnected. Resolder everything again on that wire.

ok

Today Vedant had come to my house to test the motor.
We found that some of the wirings in the motor had broken.
when we connected the motor and esc and the battery the esc got very very hot,and finally was in flames and burnt in front of us!

RIP esc

Please Guys

Please what ???

Damn!! RIPESC. But why did you connect it when you knew it had broken wiring ???

We found it later.

Ok! so whats the plan now. I guess you'll have to buy new motor and ESC, it wont be a good idea to risk another ESC on a broken motor.

Yes. I am going to buy a new motor and ESC

This is definately a connector problem! Just wish i had seen this earlier.
The exact same thing happened to me - i removed bullet connectors on all 3 wires and soldered directly to ESc and it worked fine. Remember if the motor wriggles ONE OR MORE WIRES ARE NOT GETTING POWER!!!

My video is the same as yours :(

yes they are right, touching up of any 2 of the 3 wires of motor when the circuit is on, can lead to a bad damage of "esc". moreover if lipos are connected this might result in fire.....
plz be safe.........
