A system for providing electric motor control to a plurality of motor loads. The system comprises a plurality of motor controllers that are configurable into different arrangements of motor controllers. The system further comprises a central controller that is operable to individually set a phase and/or frequency of respective PWM carrier signals for the motor controllers, wherein the central controller is configured to set the phase and/or frequency of the PWM carrier signals for the motor controllers within a respective arrangement of motor controllers differently depending on the configuration of the motor controllers within the arrangement.
