Low cost brushless direct current motors are becoming more prevalent, especially from the hobby remote control community. These motors often have the required high-torque density; however, they also have significant torque ripple. This video and accompanying paper presents a low cost method for anticogging, the compensation of cogging torque.
I will be referencing this paper in my MSME thesis. Thank you!
Basically this anticogging technique comes down to fine grained torque control individualized to each motor's unique torque ripples vs just assuming a standard sinusoidal torque ripple for all motors
so..smoother operation, less vibration, no jello in flight video and better servo resolution. is power consumption higher with anti-cogging on? Is this tech going to be available for manufacturers to implement? Great work, we want.
how exactly was torque, current, and position measured? What setup was used? Wouldn't current readings be useless.
Great work!
Great work!
good work man
How to feedback motor's position at real time?
Wonderfull! Now do it again without the absolute position encoding.
Very Cool!
big up
Now if you could get this tech into some cheap hobby brushless controllers maybe the brushless wltoys cars would run better :P
you should start selling cheap gimbals and other things :D
It's pure software, you could apply it to your existing brushless sensored motor if you can mess with the controller. Think of it like microstepping a stepper without the loss in torque

Do you know what are hardware and software he use to get rid of the ripple
Please tell me it will mean the world to me
Inspiring job, congratulations !
Nice explanation!
