Motor grounding seal
A shaft seal assembly is disclosed having a stator including a main body and axial and radial projections therefrom. The rotor may be radially extended to encompass the axial and radial projections from said stator. A passageway formed between the radial projection of stator and rotor results in an...

| description | A shaft seal assembly is disclosed having a stator including a main body and axial and radial projections therefrom. The rotor may be radially extended to encompass the axial and radial projections from said stator. A passageway formed between the radial projection of stator and rotor results in an axial passageway having its opening facing rearwardly from the rotor and away from the source of impinging coolant and/or contaminant. A concentric circumferential receptor groove in the stator facing the housing allows insertion of a conductive insert for transmission of electrostatic charge away from the shaft through the shaft seal assembly to the housing and ground. The receptor groove is opposite the axial passageway and provides for both a substantially lower contaminant environment and improved engagement with the conductive insert. |
