I know this video is getting old but I had a quick question. Are there motor control approaches that invert the current of a pole pair as the magnet passes over top in order to add a repulsive force in addition to the attractive force from the next pole pair?
Bldc stators can be stacked and wound with thicker conductors to create more current. Multiple stators can be aranged to create as much torque as we need.
Ya know, I've been working as an Electrical Engineer for 12 years and I actually had to look up what BLDC stands for. Sometime we get a little too acronym crazy in this industry. What exactly is the point of shortening a two syllable word like brushless to a two syllable acronym like "BL"?
Hi Nikola. Magnetic encoders and resolvers are more robust and reliable. Optical encoders are typically made of a code disk with a pattern on it, LED, and photoreceptors. Infrared light from LED is shined through the code disk and unique combination of photoreceptors is illuminated to identify a given position of shaft. Optical encoders with this kind of construction give very high resolution but their assembly is complex and does not sit well with vibrating and noisy environments. In general Magnetic and Inductive encoders (like resolvers) will be more immune (although lower resolution) as compared to general optical encoder. If you have other questions, feel free to ask the experts in the E2E community: e2e.ti.com/support/sensor/
okay that is a 3-phase BLDC motor but i want to know that how single phase BLDC motor will be work with hall sensor ?? i am student of electrical engineer and my final year project is related to it so if you would help me on this i would be thankful to you sir !!

As he said the coil creates a magnetic field (B) and is proportional to K - Permeability constant (sometimes they put a specific material inside of the coil to increment this constant and get a bigger magnetic field ) N - is the number of loops of the coil I - is the current Sorry about my english.
Thank you very much, is annoying there is absolutely no clear info how a computer fan works on google, I've never would of thought that all motors are AC current devices, I always thought that an electric motor was just a coil and a magnet and you just put energy to that and rotates, when I have to repair a laptop CPU fan now i understand how complex it is. To this day all the designs out there are extremely difficult that you may think just a 2-stroke gasoline engine is simpler. Complex designs may sound okay but for practical uses or mass production they are not an option, a design of a device that is put to work into the economy must have the less parts possible the less complexity possible, if not, that economy is going to deficit. To keep the equilibrium in the thermodynamics system is so delicate that every machine that is designed to have a sustainable economy in the world must be reduced at minimum.
Sounds like an interesting project! Our experts in the E2E maybe able to provide advice, or you can search for help here: e2e.ti.com/support/applications/motor_drivers/

Awesome crystal clear communication. I really appreciate!
Thank you so much. The video is extremely helpful!
Very helpful video! Thanks!
Well presented easy to understand and future oriented video.
Straightforward and simple comment, Gerard. And I'm in total agreement with it.
Thank you very much
Thank you teacher
Very important video
I know this video is getting old but I had a quick question. Are there motor control approaches that invert the current of a pole pair as the magnet passes over top in order to add a repulsive force in addition to the attractive force from the next pole pair?
Where is the video for the sensorless BLDC motor operation?
could you please explain the types of bldc motor -inrunner and outrunner
AWESOME

Spin permanent magnets around stator cores. I have inversion contacts for your application.
Thanks

keystoneclimber It's shorter to write
Could you please give us example why does optical encoder ( especially absolute ) has got low reliability?

0:30 Can you explain this equation?B=KNI
As he said the coil creates a magnetic field (B) and is proportional to
K - Permeability constant (sometimes they put a specific material inside of the coil to increment this constant and get a bigger magnetic field )
N - is the number of loops of the coil
I - is the current
Sorry about my english.
Thank you
@@henriquegapo1287 Your English is fine... Brilliant explanation!
@@henriquegapo1287 Thank you, just the equation I was trying to find since time I was in school many years ago.

yes u r first who is now y motors is running u r first even u can ask any the electric engineer can't answer u
Very useful
I also posted some bldc motor project pls see
Hiii how i start hoverboard motor without using hall sensor plz help
