Rewinding bldc motor. Post by: prabal276 on July 24, 2018, 04:41:58 PM There is a very detailed thread on rewinding. Contains every detail. Please search it.
The motor wouldn't have been damaged by a simple fall. Motors are very robust. A ESC can't damage a motor at all. Have you checked for a broken connection using a multimeter ? (continuity feautre) Regards Title: Re: ESC fried & new motor got problem. Rewinding bldc motor. Post by: prabal276 on July 24, 2018, 04:54:02 PM This is the thread:

I have checked continuity and beep sound comes. This means continuity is okay. kaante ne voltage regulator ki ek pin ko microcontroller se attached ho gaya tha... isliye bol raha hu ... ki esc ne motor kharab kardi.

I checked as you said. And result is fumes comes from motor. :banghead: Title: Re: ESC fried & new motor got problem. Rewinding bldc motor. Post by: prabal276 on July 24, 2018, 05:04:50 PM That motor is damaged too. Maybe some wires inside are shorting. Have you checked the ABC leads for a short?
You may have to tear the black Heatsink. Title: Re: ESC fried & new motor got problem. Rewinding bldc motor. Post by: taksh on July 24, 2018, 05:09:13 PM @prabal276
ESC was old only 4-5 times used and motor was new. I just unpacked and fitted in my quad to go for flying. heat shrink is same as comes with plastic case. bhai dittu motor same hai yaar.. kuch nhi hai baas chal nhi rahi. Title: Re: ESC fried & new motor got problem. Rewinding bldc motor. Post by: prabal276 on July 24, 2018, 05:13:38 PM I asked you to check under the heatshrink if there is any short due to unwanted bending of wires.
If you don't find anything then better get a new motor. They are dirt cheap anyways. Title: Re: ESC fried & new motor got problem. Rewinding bldc motor. Post by: taksh on July 24, 2018, 05:18:45 PM @prabal276

Aggr motor thik ho jaye tho plane ka liya tho work karegi heee.. quad ka liya dusri aur nayi motor karidh lunga All thing is okay with motor but i don't know what happened to motor. but I want to send motor to someone who can check motor & can fix the motor.

Remember rayofhope? He may still have some 2212 motors and ESCs Regards Title: Re: ESC fried & new motor got problem. Rewinding bldc motor. Post by: prabal276 on July 24, 2018, 08:19:01 PM Oh yes!
A great suggestion! I just couldn't remember the name. I was going to suggest rayofhope as well. Now I found his name. Title: Re: ESC fried & new motor got problem. Rewinding bldc motor. Post by: taksh on July 25, 2018, 05:48:06 AM @K K Iyer Sir
Rayofhope is selling motor and esc? Title: Re: ESC fried & new motor got problem. Rewinding bldc motor. Post by: prabal276 on July 25, 2018, 06:30:21 AM There is this person with handle @ rayofhope on this forum.
He had bought BLDC motors, 30 amp Escs in wholesale to start a venture. Due to unforeseen circumstances, he can't continue that venture anymore. He was selling the motors a lot cheaper than on the market. Buy from him. Title: Re: ESC fried & new motor got problem. Rewinding bldc motor. Post by: taksh on July 25, 2018, 06:43:42 AM @prabal276
Okay. I am trying to contact rayofhope. |
