FAQs
When planning installation, verify mounting compatibility with a 447TC frame, confirm 3PH electrical supply, and align the shaft properly to avoid vibration. Use standard mounting hardware and ensure grounded connections meet safety requirements. With 0-day lead time stock, consider pre-assembly checks to minimize commissioning delays. Coordinate with electrical and controls teams to confirm shaft alignment tolerances and to plan for variable frequency drive setup and fault diagnosis readiness.
Key performance specs include 250HP output, 1785RPM nominal speed, 3-phase power, and operation across 6-60Hz, enabling flexible drives on varied grids. The 447TC frame supports easy retrofits with common gearboxes, while the A441 designation ensures component consistency. This combination delivers high startup torque, smooth acceleration, and reliable long-term operation in demanding conveyor and pump applications.
Certification details vary by region and supplier. For applications requiring IP protection, CE compliance, or SIL safety ratings, confirm with the distributor for the specific configuration and regional approvals. ABB-based solutions typically align with standard industry safety practices when specified.
Lead time is listed as 0 day, with stock maintained at multiple warehouses including USABB014EXPU, GBINS001EXPU, SGIND004EXPU, and EGAUT001EXPU. This distribution enables rapid quoting, faster procurement, and reduced project downtime for critical line upgrades.
Shaft-ground motors provide a dedicated grounding path that minimizes stray voltages and electrical noise, improving sensor accuracy and reducing arc risk. This design supports safer startup sequences, easier diagnostics, and enhanced protection for downstream drive systems in automated lines.
