Hardware hack a BLDC as an AC servo motor

[@nostamine2567]

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 :)

Some wear shorts

Thanks for explaining Ian!

This was very informative! Thank you!❤

This is a goldmine yet to be discovered

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.

Where can we find a copy of your code?

[@viktorfreeman3607]

Thank you a lot. This information was very usefull for me.

Have a question how to make it closed loop?

Thank you, congratulations from Brazil.

Do you have a link for the motors?

[@samuel-br.man__3571]

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

[@atVo-vj7em]

Have you done it yet? Can you guide me because I also want to do this project. Thank you

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?

[@Gragoon]

hey, did you manage to do this ?

[@justinc2633]

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
