generate your own commutation table part 2 - motor drive

dec 20 but that's not quite right many times motors are able to rotate even using one or two wrong sequences so determining the right commutation sequence is very important to get efficient control we also previously covered a method to generate the commutation table based on three-phase motor back emf

commutation techniques for three phase brushless dc motors ti

today i would like to discuss various commutation methods for 3-phase bldc motors in a 3-phase bldc motor system there are 3/2 h-bridges used to control the current being delivered to the phases of the motor there are 6 different commutation cycles per electrical cycle to move the rotor between 2 poles for a 4-pole
