I am still curious as to how a brushless ESC works? I get the switching power supply bit, I more interested in how a standard brushless ESC can control the varuious styles of motors with differing poles and running at different speeds and still effectively control the motor, most are listed as sensorless but they must be using some type of feedback, yes? I have found several articles on the web on how the various brushless motors work but nothing on their speed controls.
