The patented RE3000 shaft grounding system is designed to mount onto 56 c-face applications such as resolvers or tachometers. In its standard form, it does not mount directly to the motor. If there is a need to mount this system directly onto the motor, then other custom systems are available. This system requires about 1 inch of axial clearance and the tachometer or resolver must be connected to the motor shaft with a conductive coupling.
