Feature → Business Impact → Application: Shaft Ground provides a dedicated grounding path for motor shafts, reducing stray currents and bearing wear, which translates to lower maintenance costs and longer motor life in continuous-duty applications. By aligning with a TEFC enclosure and a 56C frame, installation is straightforward on standard 56C motors and compatible drive systems, delivering predictable performance in conveyors and pumps. This accessory supports 208-230/460 V, 60 Hz, three-phase operation, enabling seamless use across global facilities while maintaining compliance with industry standards. The compact 0.5 HP configuration minimizes space while maximizing reliability, helping OEMs and maintenance teams meet uptime targets. In practice, engineers appreciate the direct mounting options (C-face, foot-mounted) and the clear wiring guidance, which reduces commissioning time and startup risk. The solution also aligns with NEMA B design class, ensuring predictable torque and efficiency alignment with existing motor stacks, reducing retrofit headaches in retrofits and expansions. In real-world plants, shaft grounding translates into measurable EMI reduction and bearing protection, supporting longer lubrication intervals and reduced noise in equipment such as fans, pumps, and material-handling hardware. Teams can stock a standard part with worldwide availability, improving procurement predictability and total cost of ownership over time.

FAQs
The Shaft Ground is designed for 56C frame motors with C-face mounting and a foot-mounted base option. Mounting is straightforward on TEFC enclosures, and wiring follows standard grounding practices to connect the shaft grounding path to the motor frame. Ensure the motor is de-energized, align the shaft ground component with the hub, and secure with the appropriate fasteners. This minimizes installation risk and supports quick commissioning in new builds or retrofit projects.
This accessory is designed for 3-phase operation at 60 Hz with a voltage rating of 208–230/460 V. The motor it pairs with is rated at 0.5 HP, 1770 RPM, and uses a 56C frame with TEFC enclosure. With a shaft diameter of 0.63 in, the grounding accessory integrates cleanly into standard Baldor-ABB motor assemblies, ensuring compatibility across common industrial drives and protections.
Yes. The product carries CSA, CSA EEV, and UR certification approvals, and aligns with NEMA design standards. This combination supports regulatory compliance in North American facilities and jibes with typical OEM and end-user QA requirements, reducing qualification time for new machinery or expansions.
Shaft grounding reduces stray currents that accelerate bearing wear and can worsen EMI. By stabilizing electrical paths, it extends bearing life, lowers lubrication and maintenance costs, and improves operational uptime. The result is less unplanned downtime, lower total cost of ownership, and more predictable performance for conveyors, pumps, and fans.
The C-face mounting and 56C frame compatibility enable straightforward integration with standard Baldor-ABB motors. It supports both foot-mounted bases and horizontal mounting configurations, and its TEFC enclosure suits harsh environments. Whether upgrading a legacy line or configuring a new plant, the Shaft Ground fits into typical motor stacks with minimal rework and rapid commissioning.
