"Nettet17. des. 2024 · The process in which reversal of current from one direction to another during the period when a coil is short-circuited by a brush without any sparking is called 'Commutation'. The short-circuited period of the coil with the brush is very short order of 0.0005 to 0.002 sec, it is termed as 'Commutation Period'. " - Linear motor commutation
