13. A method of operating a motor, the method comprising steps of
providing an electric system coupled with the motor, the electric system including parallel inverter legs, wherein the parallel inverter legs are part of a coil-integrated inverter system having a distributed inverter system, wherein the distributed inverter system includes a first plurality of inverter legs and a second plurality of inverter legs, wherein the first plurality of inverter legs is at an angular displacement angle relative to the second plurality of inverter legs;
subjecting the motor to a first interleaving angle when the electric system is under a first condition; and
subjecting the motor to a second interleaving angle different from the first interleaving angle when the electric system is under a second condition;
wherein the steps of subjecting the motor to the first interleaving angle and subjecting the motor to the second interleaving angle occur within continuous operation of the electric system and the motor.
