AEGIS Shaft Grounding Rings give VFD-produced shaft currents a
low-impedance path from the motor shaft to the motor frame. But the
motor must also be properly grounded: there must also be a
low-impedance path from frame to ground...
AEGIS High-Frequency Ground Straps (HFGS) are specially engineered
to provide a low-impedance path for high-frequency currents from
the motor frame to ground, in accordance with several major motor
and drive manufacturers' recommendations....
Together, AEGIS Shaft Grounding Rings and HFGS ensure that
potentially destructive VFD-produced high-frequency currents have a
safe path from the motor shaft to the frame, and then from frame to
