I think it's more the esc's software/hardware to detecting rpm/rotor position which causes cogging... because, even if the motor is spinning at say 60rpm, there will be a voltage generated, albeit, small potential. It's just up to the tech of the controller to be able to 'see' this potential, past all the other electrical noise, w/e.
