ABB 7BA44-8366-3520 Shaft Ground Motors - 300HP
Part Number: 7BA44-8366-3520
Quick Summary
Shaft Ground Motors by ABB provide rugged, high-power rotation for demanding industrial drives like conveyors and processing lines. Uptime challenges from grounding faults, EMI, and misalignment can derail schedules; these motors are designed to minimize those interruptions and keep lines running. In deployments across heavy industries, customers look for CE, UL, and IP-rated protection to meet safety and environmental requirements, and this model aligns with those expectations. The combination of robust mechanical performance and reliable electrical design translates to lower maintenance costs and longer service intervals. With stock in multiple warehouses and 0-day lead times, ABB enables faster project execution and predictable total cost of ownership for US and global manufacturing customers.

FAQs
Ensure proper mounting to a rigid base, verify correct alignment with driven equipment, and use appropriate grounding practices to minimize EMI. The unit is designed for compatibility with standard motor controls and can leverage existing VFDs for smooth acceleration, reducing mechanical stress during startup.
The 3PH 60Hz rating at 1190RPM makes it compatible with most industrial VFDs and drives. Use properly rated VFDs to manage start‑up torque and speed control, and ensure cooling and wiring meet electrical codes for high‑power applications.
Yes. The 300HP rating provides strong starting torque and sustained output for demanding conveyors and pumps. With a 1190RPM speed, it supports moderate-speed applications while maintaining efficient energy use and reliable control with standard drive systems.
Industry deployments typically require CE and IP-rated protection, with UL recognition where applicable. While the product data confirms origin and compliance expectations, confirm exact certification scope with your ABB distributor for your region and application.
ROI derives from reduced downtime due to lower grounding faults and EMI, improved drive efficiency, and longer maintenance intervals. Combined with 0-day lead times and strong regional stocking, project timelines shorten and total cost of ownership improves for continuous operations.
