I’m pretty sure you have to fire at least 4 igbts simultaneously and shortly there after all 6 to recreate the three phase sine wave relation ship due to winding the stator in delta. Energizing 1 phase will put the other two phases in series and in parallel with the energized phase…Right?

My first experience with a brushless DC motor came in 1978 when I built a floppy disc controller. The head positioning mechanism was driven by a brushless DC motor called a stepper motor. I can step the motor at a constant rate, or I could step the motor with acceleration, negative or positive. Steppers are marvelous devices that can accomplish things you couldn't do with a standard DC motor. For instance, you could hold the motor in a very specific position over a given track, and you can't do that with a standard DC motor. If you energize one coil it will lock the head in place and it will not move in or out.

I really enjoy things like this. You have a great way of explaining things. Back when I was growing up we did not have the internet most definitely did not have computers. None of that stopped me from learning on how things work. At that time radio shack was a great place to find things that helped you to learn about electronics. They had different type of electrical kits that you put together and it explains what each part did. Every year they used to come out with a catalog and from that I could find different components and build things from scratch. As I was getting older my attention turned to other places. For a very long time I never messed around with electronics. All that changed about 10 years ago. I broke my back and I started looking for things I could do to keep me occupied and I made my way back to electronics. Of course everything is completely different than it was when I were growing up. I really enjoy your videos I have been a subscriber for a good bit of time and always enjoy watching new videos. Looking forward for watching your next video.

I made tooling to wind them on my two pole powered winder. 70% time reduction for high voltage windings but not faster for low voltage because of cycle time resetting the stator on it vs horizontal vice tooling.

Amazing, and far superior to the larger, brushed motors in my other drones. Conversions to E-bikes are one of the best ways to learn the concepts of brushless motors. Of course, dealing with DIY robots, these motors have their uses, along with their cousins the servo motors. I have been playing around with these things for years, but when someone asks me to explain whats going on inside, I can never do it properly. You have been a great help to me, and thank you.

I first came across them, as rack mounted fans that featured diminutive size compared to commutator designs in a location where synchronous motors could not have worked due to a lack of an A/C supply. You provided a description that was both wonderfully clear and devoid of any complexity. Essentially, the motor is always playing-chase-my-tail with the alternating fields generated by the different phases. I found it a fascinating use of techniques allowing relatively simply implementations.

I was in automation/motion control and did applications in everything from manufacturing of knives, wood paneling to assembling of planes to candies. I miss it but once you're 40, you're out, and there's very little manufacturing anymore. Everything was custom and new when I was involved, now new is outsourcing to Shenzhen instead of Malaysia.

Great video, but this topic considers only one type of control algorithm, sensor less 6-step which has some disadvantages. This algorithm is the most basic and closely emulates the mechanical commutator. Sensored Direct Torque Control and Field Oriented Control are the methods of choice for professional motor applications. They don't have problems at zero RPM. I would have cut out the whole section about the interface between the motor controller and the controlling device. 1-2ms PWM is only used in the RC hobby. And even that is obsolete now, replaced with more advanced protocols like OneShot and Dshot. Motor controllers in other applications (eBikes, EVs, industry) will use analog voltages or digital communication over RS232, RS485, CANbus, etc)

@@jarkstt control over a "BLDC" can get quite advanced. So the controllers should be optimized for a specific job. Odrive uses BLDC motors with tight positional control in a closed loop (feedback from a high resolution encoder. The interface for that is similar to stepper motor controllers since the target application is CNC. EV's on the other hand do not need tight positional control, instead the throttle controls the torque of the motor, which indirectly controls the velocity of the vehicle, it's a second-order system with the pilot or driver being the thing that closes the loop (driving). This application requires the motor operate in all 4 quadrants (spins both ways, and with regenerative braking) With FOC you specify the desired torque and the controller adjusts the current in the phases to maintain generated field 90° ahead of the rotor and uses a PI control loop to regulate the current to achieve desired torque. Then optionally another control loop governs this whole system to regulate speed. This works until the motor reaches a speed where the back EMF equals or exceeds the supply voltage. Then the requested torque can no longer be achieved since it would require either higher voltage or field weakening, which some BLDCs can do by increasing the space between the rotor magnets and stator, common on the solar car motors. Another method of field weakening to increase max speed is to change the angle of the stator field so as to cancel out some of the flux from the permanent magnets, but this consumes more power and is inefficient.

@@MrXjoeharperx my point is to generalize the video on BLDC control rather than focus on a cheap obsolete technology and its interface from Ali express or Amazon that used to be used for a specific RC hobby 10 years ago and is not really relevant anymore.

Fantastic video. Epicly so. I watched and paused and rewound every few seconds, so I could absorb as much as possible. I'm generally familiar, even having build a small motor as a child, but this video is flawless. I watch most videos in 1.5-2.0 speed. Not this one. Thanks for stuffing it full of info.

Great video! I'm curious about one thing, though-- as the magnetic field rotates due to the constant pushing and pulling of polarity, is there a difference between the pushing vs. the pulling force? Just wondering if one is stronger than the other or if the speed of rotation renders any difference to be negligible...
@bartomiej9807
@bartomiej9807 2 жыл бұрын
If the currency is the same (which should be at this moment) and distance is the same (which is basic requirement for creating an engine) there should be no difference in force between push and pull forces as they are just reactions to the same physical values but with opposite vector of the force. Correct me if I'm wrong :)

The motors only work on pulling forces of magnetic North South pairs, not repulsion of magnetic north north or SS. The Flux of the tooth/magnet pairs form a closed magnetic circuit with each other via back iron and airgap coupling.

Finally someone has said it clearly that the wire in the coil is insulation-coated. For a long time it had been a mystery to me why the current wouldn't travel the shortest way through the coil. Why do most of tutorials say 'just wind some wire into a coil, and you'll get a nice electric magnet' , assuming such important things as coating the wire are not worth mentioning?

It needs to be stated that the copper winding wire must be lacquered to insulate it. In a graphic you can't see whether it's insulated or not.
