Do you recommend a common-mode choke between the Everest power stage and the motor being driven? If so, do you have guidance on part selection?

Yes, a common-mode choke between the Everest Series power stage and motor being driven is recommended if EMIs are a concern, or if the system is in the presence of large electromagnetic fields. It is also recommended to place the common-mode choke as close as possible to the servo drive.

For part selection, if the current is not high, PCB mounted 3 phase common-mode chokes are strongly encouraged. Choose a common-mode choke part that offers 10ths of ohms of impedance, between 20 MHz and 100 MHz. LAIRD technologies has part numbers that work pretty well with our servo drives.
