Sorry, I missed this.
In the RC community the word cogging is used, and it's a misnomer. It refers to a non-sensored motor being able to start due to the static load being too high. These ESCs generally chase through the phases and assume the motor starts then measure back EMF to com mutate after. If the motor was sensored and properly communicated through this time it'd be capable of starting.
The actually definition of cogging is the torque ripple from the specific arrangement of the magnets.
