Common mode currents commonly occur from noise spikes created by the

PWM switching frequency of the drive. The use of a ferrite or iron-powder core

toroid places common mode impedance in the line between the motor and the

drive. The use of a common mode choke on the motor leads increases signal

integrity of encoder outputs and associated I/O signals. The following is a list of

toroidal and ferrite cores used to make common mode chokes:
