@Chickenbreadlp
@Chickenbreadlp 6 років тому
I once programmed an Arduino to function as a very basic ESC. It couldn't start the Motor on it's own and changing the motor speed while the motor was spinning caused the motor to stop. But as long as you start the motor by hand and don't change the speed, it works. That was for a school project where we were supposed to build a DC motor, while many failed, and some didn't really fulfill the task, I had to overdone it ^^'
@erlendse
@erlendse 6 років тому
Neat. The issue is fidning motor position. You can use the voltage created in the coils, but it won't do the start so you will have to step it up to run-able speed. The other common option is having sensors in the motor to tell the position, and use them to determine what step to use.

@the0844
@the0844 6 років тому
I'm not entirely sure that this is how a sensorless brushless ESC works. Commercial units read the back-EMF induced in each of the coils to determine the position of the rotor and turn on the correct phases. Speed control is achieved via PWM modulation of such phases and not by arbitrarily speeding up the phase switching.

@MichelPASTOR
@MichelPASTOR 6 років тому
More fun but be aware that it will probably cost you more in parts if you do it yourself rather than buying an off-the-shelf ESC. Don't do it only to save money because it will cost you a lot more time and at best won't save much money. Having said that it is a very interesting and educational project worth doing for sure.

Great Video! you can even 3d print a frame instead of using wood also would you please condider talking about SimonK firmware, BLHeli Firmware and other popular firmwares for ESCs? im constantly burning my escs , my guess is the BEC is causing some kind of short within the ESC and burning it, but this is a great video eagerly looking forward to the second part!
@PetruSfecles13
@PetruSfecles13 6 років тому
How much current are you using? How big is the filter cap on the ESC?
@simtubes
@simtubes 6 років тому
Well, what is burning? The BEC supply and rest of the ESC are typically separate circuits. There is usually a separate regulator for the microcontroller, which is sometimes shared with the relatively low current gate drive supply where applicable. FET failures can happen for all sorts of reasons (external oscillator stopping from moisture, excessive body diode conduction, no external pull-offs to deal with MCU resets, etc), many of which can be secondary failures.
@jamesmcfarland8975
@jamesmcfarland8975 6 років тому
You probably need higher Amperage ESCs
@Afzal1995
@Afzal1995 6 років тому
Thank you guys for the suggestions I should have given a little more information, so I use the cc3d FC, best way to power it is with ESC via BEC, the ESCs are 30A SimonK and the battery is 3s lipo 3000mah 35c, everytime the ESC with which I power the quad blows out (in my case ESC 1,which is front left in an X configuration quad) I dunno what to do, I will try to order a new batch of ESCs and then supplying power to FC via PDB directly (my PDB has a voltage converter IC on board), hoping this to solve the problem, as other wise when I opened the ESC only 1 MOSFET was burned, this could have been the voltage convertor or BEC too, as it's burned so badly I can't read what's written on the package.

@PetruSfecles13
@PetruSfecles13 6 років тому
In a nutshell, when we talk about MOSFET transistors it's a technique to obtain a higher voltage level than your supply voltage. In order to correctly drive the gate of a N channel MOSFET placed in a high side topology you will need to provide a gate drive higher than supply voltage.

The gist of the difference is simple. A DC motor is just an AC motor with a controller/commutator. In other words all motors are AC internally in the sense that without a changing field it's impossible to create motion.

GreatScott! If one would want to nitpick electronic would be a little more correct. I guess it's the same like the difference between electrical and electronic engineering. Electronics is more about the working of the semiconductors, controllers,... And electrical more about power distribution, high voltage, etc. Not that they both don't have an overlap. But there is a difference, albeit a small one. Not that it actually matters that much.
