Hello friends,
I am still on journey of homemade PSOC based Hall BLDC motor driver here:
endless-sphere.com
Now I am testing with many motors and faced that timing issue that some motors turn better to one direction and not good turning at other direction. As they don't have neutral timing I can understand this effect.
While searching I saw that some motor drivers can change timing at hardware/software side, seperately from motor side. My all motors are hall sensored motors and I need to use them at also lower speeds for mobile robots so BEMF methods not solving my issue, I need to find solution with hall sensors...
How Can I add some "degree delay" to neutralize hall signals? I guess I need to make some phase shift but I couldn't find/understand alghoritm... My plan is using motors at both directions at same speed and some power levels.
I read that some drivers making with sensing RPM or adding direct delays but how.. :/
Edit: for future readers, this page also has good info on problem: Timing advance. Sensor-less vs sensored

My Brushless Design for Hall Effect Type Motors, Looking for Suggestions
Hello friends, I'm very new to the forum, but I wanted to contribute a little and share the project's changelog and get your valuable friends' ideas. I design mostly brushed motor drivers, controllers for years and trying brushless motor designs, that design is my 4th attempt and at every...
