The path in red is a capacitively coupled current from the stator to the rotor through the air gap, with a return path through the motor bearings and ultimately to the drive ground. Current may flow through the motor bearing if the shaft is bonded to the frame (through bearing ball contact) at the instant the dV/dt transition occurs in the CMV.
