I got to myself 3 phase DC brushless motor! Now i am trying to control it! So i made this ciruit! ----> http://www.mpoweruk.com/images/BLDCControl.gif <---- So i tried with 9 volt battery but battery got really hot. I tried to put some resistors (47 Ohm) but then it didn't turn. What should i do???
What should i do???
Chuck the 9V battery in the bin and get a supply rated for your motor.
(and turn your keyboard over and give it a good shake - looks like your '?' key is sticking on something)
English is not my native language! "Chuck the 9V battery in the bin and get a supply rated for your motor." <--- What does it mean? I tried with 5 volts, motor won't turn, i tried with 9 volts, battery got hot. And actually i can't fing a datasheet for my motor! I got this motor ---> 3650 3930kv 4p Sensorless Brushless Motor for 1/10 RC Racing Car Truck for sale online | eBay
The problem is not the voltage but the current. A standard 9V battery will only be able to deliver about 400mA.
You need a power supply that can deliver more amps

That's a block diagram - what actual circuit are you using?
What motor?
9V battery? Not a PP3 sized one suitable only for powering radios? No use whatsoever if so.

Chuck - to throw
bin - waste disposal holder.
To chuck in the bin - to throw away the battery because it is useless for what you want to do.
Hi,
try this for specs.
How are you controlling the what looks like an IGBT bridge.
