ohh myy god :)))) u are a genius i love u soooo much . I watched so many videos about FOC control and other bs but the sinusoidal explanation really made the difference . Thx again , not all heroes wear capes :)
im confused as to why its not able to go any faster? is this a limitation of how fast the arduino can go through all the steps? because i feel like it should be able to that within a fraction of a second. Otherwise this was a great video and ill definitely be building something similar in the near future!
Thank you very much for sharing ! I have a little question sir ! If you want to build an 3 phase inverter and you already use the maximum switching frequency for your microcontroller and still only get a sine wave of 50Hz but want say 400Hz for the Motor to get at it´s maximum speed do I have cut down the resolution in the sine wave pattern then ? Because you don´t have to use 255 steps.
Hey sir, i want to turn my 3phase bldc into a servo for my robotic arm, can tell me which one of the videos i should watch I’m really confused by all the videos
Great video. Seems like you could get away with only 3 PWM outputs, since only drive one of the two transistors per H bridge at a time (plus a digital enable to select which of the 2 transistors to drive), unless I am missing something? Also, it appears that this example is driving the coils at max voltage (or at least high enough to overcome the load torque) - my understanding is that the typical feedback allows you to drive a BLDCM with less voltage so as to reduce power and heat in the motor, right?
yeah i imagine this would get very hot as you dont have the inductive reactance from the high relative between the stator and rotor that the motor was designed to have

Some wear shorts
This was very informative! Thank you!❤
Thanks for explaining Ian!
Thank you, congratulations from Brazil.
This is a goldmine yet to be discovered
Thank you a lot.
This information was very usefull for me.

Have a question how to make it closed loop?

Have you done it yet? Can you guide me because I also want to do this project. Thank you
Where can we find a copy of your code?
Do you have a link for the motors?

hey, did you manage to do this ?
