Shaft Grounding Kits

M3 with shaft grounding brush. Click here to view the Instruction Sheet.

Shaft grounding is one of those options that can save you thousands of dollars of motor maintenance by eliminating or minimizing bearing failures due to shaft currents passing through the bearing to ground. The shaft grounding brush is used to provide those shaft currents with a low resistance path to ground. By providing this path, you also protect the bearings on connected equipment like tachometers. These brushes offer a reduction in the cost of protection since no special insulated bearings are needed on the motor and no special insulated couplings are needed for connected accessories. 

The option is especially attractive since no changes to the motor shaft are required. The grounding brush is an integral part of the encoder. A wire lug is included for a grounding cable which should be attached to ground at the other end to complete the installation. That's it! Maintenance is a breeze as well since the brush holder is mounted on the outboard side of the encoder where you have easy access. A cleanout port is included to permit routine maintenance and brush replacement as needed.

If you happen to have a motor that does not require an encoder, but still could use a grounding brush, we can offer you a special version of the M3 Universal Encoder with the shaft grounding option and no encoder electronics. Call or email us for details.

Shaft Grounding is available on the M3 and M4 Universal Encoders as well as the SMARTach^TM digital pulse generators. See the PDFs of the instruction sheets for specific applications. If you have any questions, feel free to email us for more information or application assistance.
