As i have said in the past the sensor takes no part in the turbo function ,The sensor is there to know what position the rotor is at any given time thats all mainly only good for take off which means start up torque .Anyone thats tells you otherwise are misinformed .
Two reasons only that a motor should cog on take off and conitnue cogging one is that the sensor cable is damaged or the sensor unit within the motor also known as an encoder .There are 3 types of encoders .Led,disk and hall sensor.The other reason is shorted mosfets could be phase a or b or c it all depends.If the motors starts to cog like stutter its because the sensors dont know where the rotor is positioned to actually apply the 100% power to whatever phase so it guesses and thats when you get the stutter.cogging caused mainly by a sensor being out of action .Thats when the esc will realise this problem and swap to a sensorless mode without the sensor cable being plugged in .sensorless mode does not mean less power just means the esc will apply 100% to two phases instead of one to make sure it knows where the rotor is stationed at that time of start up torque .
I hope this info helps you guys out .
