What are the Methods of Improving Commutation?Commutation definitionCommutation is the process of reversing the current in the coil to keep the motor running efficiently.There are three main methods of improving commutation. Resistance commutation E.M.F. commutation Compensating windingsResistance CommutationIn this method of commutation we use high electrical resistance brushes for getting spark less commutation. This can be obtained by replacing low resistance copper brushes with high resistan
