SmartKnob with BLDC

Hey,
This is challenging one. For now I’m using GB36-1 but it has one problem, actually two:

  • small shaft hole of only 5.7mm which forced me to use brass 5.5mm pipe as screen support.
  • diametrical magnets are sacre and only one I was able to find was 12x8x3 mm magnet.

Cogging is problem too, much better option would be GB2208 but shaft hole is only 4.7mm and if I use 4.5mm brass tube I won’t be able to fit in 8x 22AWG wires.

also it’s expensive motor.

T-Motor has other gimball motors with bigger shaft for similar price but it is nearly impossible to find diametrical magnet that would fit it.

I will see how I get on with GB36-1 after tuning and post results and CAD files.

As I said I wanted this motor as it has decent torque.

My alternative would be GL30 but these are 50USD +
