ABB 7BA44-0001-4554 Shaft Ground Motors - 500HP
Part Number: 7BA44-0001-4554
Quick Summary
Shaft Ground Motors deliver rugged power transmission for demanding industrial applications like conveyors and heavy-duty pumps. This ABB solution helps minimize downtime and maintenance costs by delivering reliable grounding and robust electrical performance. In the face of stray shaft currents, bearing wear, and grounding faults, a shaft-grounded configuration can dramatically extend motor life. Depending on configuration, these motors can meet common certifications such as CE and SIL, with IP-rated enclosures where required. For procurement efficiency, these motors are stocked across regional warehouses with 0 day lead time, enabling faster projects and consistent performance. This combination of reliability, availability, and global support translates into lower total cost of ownership for OEMs and end users alike.

FAQs
Start with verifying the 449TCZ mounting pattern and shaft alignment per OEM guidelines. Connect the three-phase power and ensure proper grounding of the shaft-grounding path. Use appropriate drive compatibility (VFDs or soft starters) and follow enclosure IP rating requirements for your environment. Confirm mounting hardware integrity and rotate the shaft to check for smooth operation before commissioning.
Key specs include 500HP output, 1780RPM, 3-phase power, and a 6-60Hz operating range, all within the 449TCZ frame. Assess service factor, efficiency under load, thermal rise, and bearing life under your duty cycle. Also confirm lead time, stock availability, and compatibility with your drive system to ensure predictable performance.
Yes, the Shaft Ground design is intended to improve grounding reliability and reduce electrical noise, which benefits conveyors and pumps in challenging settings. For harsh environments, specify IP-rated enclosures and ensure proper cooling; align the motor with your drive profile to maintain torque and speed under peak loads without overheating.
Certification availability depends on the installed configuration. Typical options may include CE marking and SIL compliance, with IP-rated variants where required. When ordering, confirm the exact regulatory requirements for your facility and region, and request a certificate of conformity if needed for your ISO or internal quality programs.
Expect improved uptime due to robust grounding and reduced electrical wear, which lowers maintenance frequency and costs. The motor’s stock-by-region availability and low minimum order quantity support faster replacements, reducing downtime. Warranty terms and easy sourcing contribute to lower total cost of ownership over the motor’s service life.
